2019–2026 GMC Sierra 1500 Upgrades, Ranked: 4 Mods for MultiPro and CarbonPro Trucks, in Order
Four upgrades for the T1 Sierra 1500, ranked in the order most owners should buy them. This truck's order is shaped by a six-function MultiPro tailgate, an optional CarbonPro composite bed that many covers exclude, a factory-lifted AT4, and Denali trims that may already have the steps you were about to buy.
- Check the bed material first. RPO E3Z means CarbonPro: standard covers exclude it, and no rack page in our guide lists it.
- MultiPro works with covers and racks. A closed folding cover can hold the inner gate shut; a retractable leaves it free.
- Trim doesn't change the floor or the rocker points. Seats and rear storage decide liners; cab and bed length decide steps.
- Look before buying steps or a hitch. GMC lists factory assist steps on the Denali, and our data lists a Class IV, 2 in receiver.
- Two Limiteds, two rules. The 2019 Sierra 1500 Limited is the old body; the 2022 Limited kept the earlier interior and the same floor.
Sierra 1500 upgrades in priority order
Each step links to a full fit-checked guide for the 2019–2026 GMC Sierra 1500.
Floor liners first: one floor under every trim, and the lowest price here
Floor liners lead on the Sierra because they cost the least and their fit has nothing to do with the bed, the tailgate or the badge. Our guide found that Denali, AT4, AT4X, Elevation, SLT and SLE Crew Cabs share one T1 cab floor, and that the 2022 refresh left it alone. Two things decide fit instead. The first is the front seats: Pro and many SLE trucks have a bench, while SLT, AT4 and Denali trucks have buckets and a console. The second is under the rear cushion, where a Crew Cab has carpeted storage, a molded plastic box or nothing. Husky's 94021 and 3W's set are listed for carpeted storage; Falafa's is cut for the box. Prices on the guide's picks run about $90–$130 for OMAC's Sierra-specific TPE set, about $100–$170 for Falafa and 3W, about $160–$230 for Husky's WeatherBeater and about $200–$260 for TuxMat, which runs up the sidewalls. The trade-off is coverage against containment: TuxMat covers more carpet, and Husky's deeper walls hold more slush. Every pick is a Crew Cab set, so Double Cab owners need their own rear piece.
Skip it if: You already run a molded Crew Cab set that matches your seats and rear storage and locks onto the driver-side retention posts.
Our best coverage: TuxMat Custom Car Mats 1st & 2nd row ($200–$260)
Compare all 5 floor mats & liners picks →Tonneau cover second: where CarbonPro and MultiPro both decide the part
A tonneau cover takes second place because it does the most for the bed, and because it's the purchase where the Sierra's two special features can cost you a return. Start with the bed material, not the length. A truck with RPO code E3Z has the CarbonPro composite bed, and BAK, Retrax, TruXedo and Tyger all exclude it from their standard short-bed parts. CarbonPro owners need a part that names it: Extang's Trifecta 2.0 92459 at about $450–$520, TruXedo's Sentry 1574301 at about $1,130, BAKFlip MX4 448135 at about $1,250 or RetraxONE MX 60488 at about $1,600. Steel beds share covers with the Silverado, from the Gator EFX at about $599 to UnderCover's painted Elite LX at about $2,250. Then think about the MultiPro tailgate. Every cover in our guide works with it, but a closed folding cover can hold the inner gate shut, so owners who use the step daily are better served by a retractable. Published load ratings run from 200 lb on the RetraxONE to 500 lb on the Elite LX; soft covers have none. Factory side storage boxes rule these covers out. If a bed rack is likely, read slot four before paying.
Skip it if: You haul loads taller than the bed rails most days, or the bed has GM's factory side storage boxes.
Our best for carbonpro beds: BAKFlip MX4 Hard Folding Tonneau Cover 448135 ($1,250)
Compare all 6 tonneau covers picks →Running boards third: first see what GMC already bolted on
Running boards rank third because a full-size 4x4 is a climb for every passenger, and on the Sierra the answer depends on trim more than any other upgrade here. GMC's 2026 pages list a 2 in factory lift on the AT4 and AT4X, which raises the step-in further, and chrome wheel-to-wheel assist steps on the Denali. So look at the rocker before you shop: aftermarket boards replace factory steps, they don't add to them. On trucks without steps, the mounting points are the same across trims, Silverado parts fit, and most kits bolt on without drilling. Three things can still go wrong. Every pick in our guide is a Crew Cab part. The 2019 Sierra 1500 Limited is the old body, and Westin excludes it by name. Wheel-to-wheel bars are sold by bed length, and Westin's 5 ft 5 in and 6 ft 5 in labels don't match GMC's bed names, so use its fit tool. Prices run about $150–$220 for 6 in boards from RHOBRA or OEDRO, about $300–$450 for Westin's polished PRO TRAXX 5, about $450–$600 for Go Rhino's galvanized RB20 and about $450–$700 for Westin's wheel-to-wheel bars. The cost is side clearance, which matters most on an AT4X.
Skip it if: Your Denali or AT4 already has factory assist steps you like, or it's an AT4X headed for rocks.
Our best wheel-to-wheel (short bed): Westin 21-534680 PRO TRAXX 5 Wheel-to-Wheel Nerf Bars Stainless ($450–$650)
Compare all 6 running boards & steps picks →Bed rack last: easy on a steel bed, a written question on CarbonPro
The bed rack comes last because the fewest owners need one and it carries the highest price on this page. For a tent camper it may still be the purchase that matters most, so read the rank as 'after the basics'. On a steel bed the Sierra is an easy truck: it shares stake pockets and bed lengths with the Silverado, and Putco, GoRack, Adarac and BackRack name both trucks. A CarbonPro bed is another matter. None of the rack pages our guide read lists the composite bed, so every pick needs the maker's approval in writing. Bed length comes next: the GoRack is a short-bed part only, Putco sells 5 ft 8 in and 6 ft 6 in versions of the Venture TEC, and Adarac and Yakima cover the long bed. Prices run from about $240 for a BackRack headache rack frame, which carries no tent, to about $693 for the short-bed Adarac, about $799 for Yakima's OutPost HD towers, about $1,090 for the GoRack and about $2,399 for the Venture TEC. Keep tent and gear under the moving rating: 600 lb on the Putco and GoRack, 500 lb on the Adarac and on Yakima's towers on-road. Racks mount ahead of the MultiPro tailgate, so it keeps working.
Skip it if: Nothing you carry is taller than the cab or longer than the bed.
Our best overall: Putco Venture Tec Rack (From $2,398.99)

| Total | About $930–$1,190 | About $1,720–$2,550 | About $2,950–$4,960, with a cover up to the RetraxONE MX |
Towing: what the Sierra already has, and one MultiPro warning
There is no trailer hitch guide for the T1 Sierra on this site, and the stored facts explain why most owners won't miss one. Our vehicle data lists a Class IV hitch with a 2 in receiver and a maximum tow rating of 13,200 lb. GMC's 2026 Sierra 1500 page quotes up to 13,300 lb, and it names the build that gets there: a Double Cab, 2WD, standard-bed truck with the available Duramax 3.0L diesel, the Max Trailering Package and 20 in wheels. Read either number as up to that figure when properly equipped.
Two cautions go with it. Most Sierras aren't that truck, and the figure for yours is on the door-jamb label and in the owner's manual. And we could not confirm from a GMC page that every trim and model year leaves the factory with the receiver fitted, so look under the rear bumper or check your window sticker before you assume. If the receiver is there, an aftermarket hitch adds nothing.
The Sierra adds a caution of its own. GMC's tailgate support page says not to open the MultiPro inner gate with the primary gate open if a hitch ball or trailer is attached, because it will damage the tailgate. A ball mount left in the receiver all year is the usual way that happens. Pull it when you aren't towing, or keep the inner gate latched while the main gate is down.
The towing money is better spent on a ball mount with the right rise or drop, a locking hitch pin and whatever brake control your trailer requires. Tongue weight counts against payload along with passengers, a hard cover, a bed rack and a tent. GMC's 2026 page lists maximum payloads between 1,950 and 2,230 lb depending on cab and bed, and your own sticker may be lower.
Steel or CarbonPro: check the bed before the catalog
The CarbonPro bed is the biggest difference between shopping for a Sierra and shopping for a Silverado. GMC says the carbon-fiber composite box weighs 25 percent less than a steel bed, roughly 60 lb, and resists scratches, dents and corrosion. For accessories, what matters is that its rails and bulkhead differ from the steel bed's, so makers treat it as a separate truck.
Find out which bed you have from the paperwork. RPO code E3Z on the window sticker or the glovebox label means CarbonPro, and CarbonPro Edition trucks carry a fender badge. GM Authority reports it was an AT4 and Denali option, standard on the 2022 Denali Ultimate, and built only as a Crew Cab short bed. A dark spray-in liner on a steel bed can look similar, so don't judge by eye. The last model year is unclear: GM Authority reported in July 2026 that the bed could no longer be ordered on a 2026 Sierra 1500, while GMC's 2026 Denali page still lists it as available. Check the code on any AT4 or Denali.
One more bed option blocks both bed upgrades on steel and composite trucks alike: GM's factory side storage boxes take the rail space that cover clamps and rack uprights need.
| Truck / bed | Tonneau cover | Bed rack | Notes |
|---|---|---|---|
| Crew Cab short bed, CarbonPro (E3Z), 69.9 in floor | CarbonPro parts only: MX4 448135, Sentry 1574301 (listed from 2020), RetraxONE MX 60488, Trifecta 2.0 92459 | No rack page in our guide lists CarbonPro; get the maker's approval in writing and don't drill | Read BAK's CarbonPro install sheet for 448135 first; RealTruck's notes mention drilling |
| Crew Cab short bed, steel, 69.9 in | Any 2019–2026 Silverado/Sierra short-bed part, such as Gator EFX GC14020 or MX4 448130 | Putco Venture TEC 5 ft 8 in, GoRack, BackRack, Yakima towers | Listings print 5 ft 8 in or 5 ft 10 in for the same bed |
| Double or Crew Cab standard bed, steel, 79.4 in | Standard-bed parts, such as MX4 448131 | Putco Venture TEC 6 ft 6 in, Adarac 6.5 ft, Yakima towers | Listings print 6 ft 6 in or 6 ft 7 in |
| Regular Cab long bed, steel, 98.2 in | Long-bed parts, such as MX4 448132 | Adarac 8 ft, Yakima towers | The fewest choices in both categories |
| 2019 Sierra 1500 Limited | 2014–2018 parts, including those labeled 2019 Limited | 2014–2018 parts | Previous-generation body and bed; not covered by these guides |
The MultiPro tailgate with a cover and a rack
GMC lists six functions for the MultiPro tailgate: a conventional gate, a primary gate load stop, an easy-access position that lets you stand closer to the bed, a full-width step, an inner gate load stop and an inner gate work surface. GMC rates the step at 375 lb, counting the person and whatever they're carrying. Its MultiPro article lists the tailgate as standard on SLE, Elevation, SLT, AT4, Denali, AT4X and Denali Ultimate and available on Pro.
None of that changes which tonneau cover fits. Covers seal on top of the tailgate and don't attach to it, so the main gate still drops. What changes is how the inner gate behaves with the cover closed. A folding cover's rear panel can hold the upper section; on the GM-Trucks thread our guide cites, an owner with a soft tri-fold says the top part won't release until the cover is opened. Flipping the rear panel forward first solves it. A retractable avoids it: with the RetraxONE MX, an owner in the same thread notes both gates still work on their own, so you can pull the cover back a couple of feet and use the inner gate as a load stop with the rest of the bed covered.
A bed rack is simpler. Racks mount at the stake pockets or on the rails ahead of the tailgate, and our guide found no MultiPro conflict. Check that rear uprights don't stick out past the tailgate opening, and that a tent or long load hanging off the back stays clear of the inner gate.
AT4, AT4X, Denali and the two Limiteds: what trim really changes
Trim names cause more worry than they deserve on the Sierra. Our guides found one cab floor and one set of rocker mounting points across the range, so a Denali badge in a listing title tells you little. These are the cases where the truck's equipment does change the plan. For the step rows, look at your own truck: GMC changed step equipment by year, and we can't confirm what any single truck was built with.
| Truck | What it has | What changes |
|---|---|---|
| AT4 | 2 in factory lift (GMC 2026 page); bucket seats; CarbonPro was an option | The strongest case for running boards if none are fitted; bucket-seat liners; check for E3Z before any bed part |
| AT4X | The same 2 in lift plus off-road rocker panel protectors (GMC) | Boards cost side clearance, and our guide points trail trucks to rock sliders; on a rack, respect the off-road rating (300 lb Putco and Yakima, 400 lb Adarac) |
| Denali and Denali Ultimate | Chrome wheel-to-wheel assist steps listed for the 2026 Denali; power steps on some trucks (GM Authority); CarbonPro optional, standard on the 2022 Denali Ultimate | Check for steps before ordering boards; check for E3Z; the painted Elite LX is the steel-bed cover that matches the truck |
| Pro and SLE | Front bench on Pro and many SLE trucks; MultiPro available, not standard, on Pro | Bench-specific front liners; ask whether the middle of the floor is covered |
| Double Cab | Shorter rear floor; standard bed | Its own rear liner (Husky's 13211 front pair is listed for Double and Crew Cab); boards must name the Double Cab, and none in our guide do |
| 2019 Sierra 1500 Limited | Previous-generation body, rocker and bed | Buy 2014–2018 parts in every category |
| 2022 Sierra 1500 Limited | Carryover truck with the earlier interior | Same floor; several liner makers list it separately, so match the listing |
Decide the rack before the cover, then install in this order
The bed rack is last on the buying list and first on the deciding list, because the rack you want can rule out the tonneau cover you were about to buy. The pairings our guides could document:
- Roll-up under a stake-pocket rack: Putco says most inside-the-rail roll-up covers work under the Venture TEC, and Agri-Cover lists its ACCESS roll-ups and LOMAX folding covers for the Adarac.
- T-slot cover: RealTruck says the GoRack can mount to a T-slot bed cover, and Retrax sells the PRO XR with T-slot rails, including a CarbonPro version, T-80488.
- Clamp towers: Yakima offers Tonneau Kit 1 for select covers on the OutPost HD and OverHaul HD.
- Headache rack: BackRack sells wide-top and low-profile tonneau hardware kits. RealTruck notes the low-profile kit needs two holes drilled per side, which is one to avoid on a CarbonPro bed.
Two pairings deserve a question first. A one-piece lid like the Elite LX lifts as a single panel, so ask UnderCover before planning any rack around it. And on a MultiPro truck, a folding cover under a rack still sits over the inner gate when closed, which is one more reason rack owners lean toward a roll-up or a retractable.
Then fit things in this order: floor liners (a few minutes), the cover, the rack over it, and running boards whenever they arrive. After the rack is torqued, check the tailgate, the inner gate and the view of the third brake light at the top of the cab, then re-torque after the first drive.
On a tight budget, the first two items do the most. OMAC's liners plus either Extang's CarbonPro-listed Trifecta 2.0 or, on a steel bed, the Gator EFX come to about $540–$730.
What to avoid
Standard short-bed parts on a CarbonPro truck. BAK, Retrax, TruXedo and Tyger exclude the composite bed from their standard covers, and no rack page in our guide lists it. Find RPO E3Z before you order anything for the bed.
Buying by the badge. Denali or AT4 in a listing title doesn't tell you the seat layout, the rear storage, the bed material or whether factory steps are fitted. Check the truck, not the trim name.
Listings titled 2014 and up. The T1 body and bed were new for 2019. Older-spanning titles need the maker to confirm the 2019+ part, and the 2019 Sierra 1500 Limited takes 2014–2018 parts.
Dropping the inner gate over a hitch ball. GMC says opening the MultiPro inner gate with the primary gate open and a hitch ball or trailer attached will damage the tailgate. Pull the ball mount when you aren't towing.
Frequently asked questions
What should I upgrade first on a 2019–2026 Sierra 1500?
Floor liners, then a tonneau cover. Liners cost the least, from about $90 for OMAC's TPE set to about $260 for TuxMat, and their fit ignores the trim badge: front seats and rear under-seat storage decide it. The cover comes second because it's where the Sierra's two special features matter. Check for the CarbonPro bed before you read a part number, then think about how often you use the MultiPro inner gate. Running boards follow, unless the truck already has factory steps. A bed rack comes last, but decide on it before you pay for the cover.
Do I need to buy a trailer hitch for a 2019+ Sierra 1500?
Probably not, but look before you assume. Our vehicle data lists a Class IV hitch with a 2 in receiver and a maximum tow rating of 13,200 lb, and GMC's 2026 page quotes up to 13,300 lb for one diesel Double Cab build. We couldn't confirm from GMC that every trim and year has the receiver fitted, so look under the rear bumper or read your window sticker. If it's there, an aftermarket trailer hitch adds nothing. Your own limit is on the door-jamb label and in the owner's manual.
How much does it cost to add all four upgrades to a Sierra 1500?
From the prices on our four guides' picks, a budget build runs about $930–$1,190: OMAC liners, an Extang Trifecta 2.0 on a CarbonPro bed or a Gator EFX on a steel one, 6 in boards and a BackRack headache rack frame. A mid build runs about $1,720–$2,550 with 3W liners, the Gator EFX or TruXedo's CarbonPro Sentry, Westin's cab-length PRO TRAXX 5 and an Adarac or Yakima OutPost HD. A premium build with Husky or TuxMat liners, a BAKFlip MX4 or RetraxONE MX, Go Rhino or wheel-to-wheel Westin steps and a GoRack or Putco Venture TEC runs about $2,950–$4,960. All figures are approximate.
How do I know if my Sierra has the CarbonPro bed, and what does it change?
Look for RPO code E3Z on the window sticker or the Service Parts Identification label in the glovebox. GM Authority reports CarbonPro was an AT4 and Denali option, standard on the 2022 Denali Ultimate, and offered only on the Crew Cab short bed. It changes both bed upgrades. BAK, Retrax, TruXedo and Tyger exclude it from their standard short-bed covers and sell separate CarbonPro parts, and none of the rack pages our guide read lists it. Floor liners and cab-length running boards aren't affected.
Does the MultiPro tailgate limit which tonneau cover or bed rack I can buy?
Not the fit, but it can change which type you want. Covers seal on top of the tailgate, and BAK, Retrax, TruXedo, Extang and UnderCover list MultiPro compatibility on the parts in our guide. The catch is the inner gate. With a folding cover closed, the upper section can be held shut; one GM-Trucks owner with a soft tri-fold reports it won't release. Flip the rear panel first, or choose a retractable such as the RetraxONE MX, which opens on its own. Bed racks mount ahead of the tailgate, so they don't change how it works.
Can I leave a ball mount in the receiver with a MultiPro tailgate?
You can, but change how you open the tailgate. GMC's tailgate support page says not to open the inner gate with the primary gate open if a hitch ball or trailer is attached, because it will damage the tailgate. So any inner-gate function you use with the main gate down is off limits while a ball mount is in the receiver. Pull it when you aren't towing. GMC's page names a hitch ball and a trailer only. For a hitch-mounted bike rack or cargo carrier, ask the maker about MultiPro clearance before you order.
Do I need running boards on a Sierra Denali or AT4?
Check what's already there. GMC's 2026 page lists chrome wheel-to-wheel assist steps on the Denali. GM Authority reports power steps were optional on the 2023 Denali and standard on the Denali Ultimate, and that power-retractable assist steps were offered for 2024 on Denali, Denali Ultimate, AT4 and AT4X. We can't tell you what your truck was built with, so look at the rocker. Aftermarket boards replace factory steps; they don't bolt on beside them. An AT4 without steps is the strongest case for a set, because GMC lists a 2 in factory lift on it.
Can I run a tonneau cover and a bed rack together on a Sierra?
Yes, if you choose them as a pair. Stake-pocket racks leave the rails free: Putco says most inside-the-rail roll-up covers work under the Venture TEC, and Agri-Cover lists its ACCESS roll-ups and LOMAX folding covers for the Adarac. RealTruck says the GoRack can mount to a T-slot cover, and Yakima offers Tonneau Kit 1 for select covers. On a CarbonPro truck there are two hurdles: the cover needs a CarbonPro part number, and the rack needs the maker's approval for the composite bed. Retrax sells a railed PRO XR, T-80488, for that bed.
Is my Sierra 1500 Limited covered by these guides?
It depends on which Limited you have, because GMC used the name twice. The 2019 Sierra 1500 Limited is the previous-generation truck sold alongside the new T1. It has the old body, rocker and bed, so it takes 2014–2018 covers, racks and boards, and Westin and Tyger exclude it by name from their 2019+ parts. The 2022 Sierra 1500 Limited is different: per our floor liner guide it's the carryover truck with the earlier interior. The floor didn't change, though several makers list it separately.
Will 2019–2026 Sierra upgrades fit the 2027 Sierra 1500?
Don't assume so. GMC calls the 2027 Sierra 1500 a next-generation truck, with a redesigned cabin, a more upright exterior and a revised MultiPro tailgate, and GM Authority reported that the CarbonPro bed isn't expected to return on it. Our four guides cover 2019–2026 only. A few listing titles already stretch to 2027, such as one Putco rack listing that reads 2014–2027, which is a reason to ask the maker, not proof of fit. Wait for a published 2027 part number, and on a 2019–2026 truck skip anything sold only for 2027.
On the 2019–2026 Sierra 1500, buy floor liners matched to seats and rear storage first and a tonneau cover matched to bed material and length second, then running boards if the factory didn't fit steps, and a bed rack last, with the rack decided before the cover.
The T1 Sierra is an easy truck to accessorize once five facts are written down: cab, front seats, rear storage, bed length, and steel or CarbonPro. Floor liners need the first three and cost the least, so they go first. The tonneau cover needs the last two, and it's where the MultiPro tailgate earns a thought, because the cover type decides whether the inner gate is free with the bed closed. Running boards take third place on height, most of all on an AT4 with its 2 in factory lift, with the caveat that a Denali may already have assist steps and every pick in our guide is a Crew Cab part.
The bed rack sits last because few owners need one, and CarbonPro owners should treat it as a question for the maker, not a catalog order. Look under the bumper before budgeting for a trailer hitch, and keep a hitch ball out of the inner gate's way. Steel-bed Sierras share nearly every part with the Silverado 1500; the CarbonPro bed and the 2019 Limited are the exceptions. Each linked guide covers the fit details for its category.

Open the Sierra 1500 fit hub →How we wrote this
We did not install any of these parts ourselves. The order comes from our four fit-checked 2019–2026 Sierra 1500 guides, weighing how many trucks each upgrade suits, what it costs, how often it's used and how many fit traps it carries on this truck (bed material, tailgate, bed length, cab, seats, trim). Price bands are the prices listed on those guides' picks, checked at maker and retailer stores in September 2026, and are approximate. Vehicle facts come from our vehicle data, the guides' sources and GMC's own 2026 Sierra and MultiPro pages, read in October 2026. Where we couldn't confirm a factory detail, the text says so.
