Best Tonneau Covers for 2019–2026 Ram 1500: 6 Picks Matched to Bed, RamBox and Tailgate

The MX4 is the benchmark folding cover, and the 448227 is the version most DT owners need: 2019–2026 Ram 1500, 5'7" bed, no RamBox, standard tailgate. BAK uses aluminum panels reinforced with high-density polymer and rates the cover at 400 lb evenly distributed, enough for a snow load or a sheet of plywood laid flat. The latches close automatically, the cover sits flush with the bed rails, and BAK says the third brake light stays visible in every fold position. RealTruck lists it at $1,049.99 (list $1,199.99).

The MX4 lineup has a matching part for nearly every DT configuration. The 448227RB for RamBox trucks works with or without the multifunction tailgate and costs $1,099.99. The 448226 for non-RamBox trucks with the split gate costs $1,249.99 at RealTruck. Its Amazon title reads 2020–2026, so 2019 owners should ask the seller. The 448223 covers the 6'4" bed. BAK puts install at 30 minutes or less with no drilling, and the warranty is five years. The cover clamps inside the rails, so the stake pockets stay free for tie-downs.

The Gator EFX gives you a lockable aluminum hard cover for about half what the BAK costs. The GC34008 is listed for the 2019–2026 Ram 1500 5'7" bed without RamBox and without the multifunction tailgate, and RealTruck prices it at $599. The panels are multi-layer aircraft-grade aluminum and are rated for 300 lb evenly distributed. That is less than the MX4, but enough for snow and light gear laid flat.

Folded, Gator says the EFX leaves about two-thirds of the bed open for tall cargo, and the stake pockets stay usable, which matters if you run a rack or tie-downs there. It clamps on in 30 minutes or less with no drilling. As with the others, the TRX bed bar has to come off. The main trade-off is the warranty: two years against five for BAK and three for UnderCover. On Jeep Gladiator forums, EFX owners report two-plus years of dry beds, which is a fair indication the design seals well when installed carefully. The GC34009 covers the 6'4" bed with the same RamBox and tailgate restrictions.

The UnderCover Flex matches the MX4's 400 lb rating and adds one thing the others don't have: it folds all the way up flush against the rear window, held by built-in prop rods, so you get 100% of the bed. Or you can strap it at the two-thirds position for everyday runs. That helps on a 5'7" bed, where a few inches of folded stack decides whether a dirt bike or an appliance box fits. The panels are aluminum-skinned with a gloss black finish.

The FX31008 is listed for the 2019–2026 Ram 1500 5'7" bed, not with the multifunction tailgate, and RealTruck prices it at $1,099.99. It installs in under an hour without drilling. The drawback is the warranty: three years, against five for the MX4 at nearly the same price. UnderCover lists a RamBox version, FX31011, but its Amazon title covers only 2019–2022 and says it won't work with the black track system, so newer RamBox owners should confirm fit before ordering. For the 6'4" bed, check UnderCover's listings for the matching part number.

A retractable is the only style here that opens the whole bed and still locks at any point. You can keep the front third covered for tools and leave the back open for a load. The RetraxPRO MX uses double-wall aluminum slats rated for 500 lb, and it opens and closes independently of the tailgate. RealTruck lists the 80243 (2019–2026 Ram 1500, 5'7", not for the multifunction tailgate) at $2,149.99, with a limited lifetime warranty that isn't transferable.

For RamBox trucks, Retrax sells the 80244, which RealTruck lists at $1,949.99. Its Amazon title says it fits with or without the multifunction tailgate, which makes it the easiest premium option for a truck that has both RamBox and the split gate. Install is under an hour with clamps and no drilling. The canister costs some bed length at the bulkhead, though flat sheet goods can slide under it. If you plan to add crossbars later, the XR version (T-80243) adds T-slot rails, which is the usual way to fit a bed rack over a cover.

RamBox trucks with the split tailgate have the fewest cover options, and the TruXedo Lo Pro 584901 is one of the few built for exactly that combination. Its Amazon title lists the 2019+ Ram 1500 with RamBox, with or without the multifunction tailgate, on the 5'7" bed. RealTruck lists it at $489.99 (list $519.99). The vinyl sits only ¾ in above the rails, so from the side the truck looks almost uncovered, and the roll-up gives back the full bed in seconds.

The Lo Pro clamps inside the bed with no drilling, and a quick-release system lets you take it off without tools. TruXedo backs it with a limited lifetime warranty. It is still vinyl, so it keeps rain and prying eyes out but won't stop a knife, and it carries nothing on top. For non-RamBox trucks with the split gate, TruXedo lists the 585801, and 5thGenRams owners report that TruXedo's included weatherstrip helps with the DT's tailgate-corner gaps. If you sell the truck, the quick-release makes it easy to move the cover to another RamBox Ram of the same years.

The Tyger T3 is the cheapest cover here that is built specifically for the new-body Ram rather than sold as a one-size-fits-many listing. Tyger lists TG-BC3D1044 for the 2019–2026 Ram 1500 5'7" bed at $237, and the title says "Not Fit 19-24 Classic". It uses dual-coated 24 oz marine-grade vinyl over aircraft-grade aluminum frames with stainless clamps, weighs 33.7 lb, and has a 5-year warranty, which is longer than the Gator EFX at more than twice the price.

Tyger's fitment notes are specific. The T3 isn't compatible with RamBox or the multifunction tailgate, and trucks with an over-the-rail bedliner need small holes cut for the clamps. Under-rail and spray-in liners need nothing. Tyger quotes a 5–10 minute install, and the tri-fold can flip up against the cab or come off entirely. The 6'4" bed has its own part, TG-BC3D1045. For RamBox trucks or the split gate, look at the TruXedo Lo Pro above instead. At 33.7 lb, one person can lift the T3 off in a minute.
