Best Running Boards & Side Steps for 2015–2020 Ford F-150: 6 Picks by Cab

AMP Research's PowerStep is the part every other power step gets compared to, and the Smart Series 86151-01A is the version listed for this truck. Motomentum lists it for the 2015–2020 Ford F-150, and the Amazon listing title covers 2015–2022. The steps fold up under the rocker when the doors are closed, so the truck keeps its clearance and clean side, and they drop when a door opens. The Smart Series adds an app, for iOS and Android according to Motomentum, that can hold the steps up or down and switch the built-in LED lights or an auxiliary light set on and off. CARiD lists the construction as aluminum with a black powder coat, an OBD connector and a wiring harness, and a 600 lb load capacity.

The cost is the price and the install. CARiD and Motomentum both list it at $1,949.99, with Motomentum showing a regular price of $2,632.49. Motomentum lists the package at 82 by 13 by 7 in and 54 lb. The warranty is 5 years or 60,000 miles, and both retailers say it is made in the USA. Neither page names a cab, so use AMP's fit tool for a SuperCab or Regular Cab, and if your Limited already has factory power boards, ask the seller before ordering. Note that the 86151-01A is listed for 2015–2020; a 2021+ truck uses a different AMP part.

Rough Country's RPT2 is the flat running board to start with on a 2015–2020 SuperCrew. Rough Country's page lists the 44005 for the 2015–2026 F-150, the 2017–2026 F-150 Raptor and Super Duty, and later the Tremor and Lightning, and says it only fits Crew Cab models and fits all bed sizes. The Amazon listing title names the 2015–2025 F-150, Lightning, Super Duty and Raptor Crew Cab. The board is steel with what Rough Country calls a wide 6.75 in stepping area, the widest step on this page, which is the number that matters if kids or older passengers climb in.

Rough Country lists it at $449.95 with free shipping, describes the install as no-drill, and covers it with a limited lifetime warranty against material and workmanship failures for the original purchaser, with the finish covered for one year. That one-year finish term is the trade-off against the HD2's aluminum or Westin's stainless in a salt state: the structure is covered for life, but chips in the black coating are on you after year one. Rough Country does not publish a load rating for it. For a family SuperCrew on paved roads, the width, the warranty and the price make it the board to buy; the sibling HD2 is the choice if corrosion worries you more than step width.

Westin's 21-534635 is a PRO TRAXX 5 wheel-to-wheel bar, and its Amazon title names exactly this truck: the 2015–2020 F-150 SuperCrew with the 6'5" bed, which is Westin's name for Ford's 6.5 ft box. A wheel-to-wheel bar extends past the rear door to the rear wheel well, so you get a step beside the bed for reaching a toolbox, a tie-down or the front of the box. On a SuperCrew with the longer bed, that is the practical reason to pick it over a cab-length bar.

The bar itself follows Westin's PRO TRAXX 5 spec: a 5 in oval tube, injection-molded polymer step pads with a 5 in wide step area, fully welded domed ends with no exposed bolt heads, and 30-degree factory-style bends at each end. Westin offers the line in polished 304 stainless steel with a lifetime warranty against manufacturer defects in materials, workmanship and finish, or in e-coated steel with black powder coat covered for three years; this listing is the black pair. Westin says installation is bolt-on with no drilling required on most applications and that a mount kit is included. Westin prints a line-wide price range of $297 to $820 rather than a price for this part, so check the listing. A 5.5 ft SuperCrew needs Westin's shorter wheel-to-wheel number; confirm the bed on Westin's fit tool before ordering.

SuperCab owners have fewer choices than SuperCrew owners, because most board makers cut Crew Cab parts first. Westin's PRO TRAXX 5 21-53935 is the black SuperCab bar, and Westin's own page lists it for the 2015–2026 F-150 SuperCab alongside the 21-53945 SuperCrew part; the Amazon title adds the 2017–2026 F-250 through F-550 SuperCab. That shared cab fitment across two generations and the Super Duty is a sign Westin cut it to the cab and rocker rather than to one model year.

It is the same bar as the wheel-to-wheel pick, cut to cab length: a 5 in oval tube, injection-molded step pads, fully welded domed ends and 30-degree bends. Westin says it bolts on without drilling on most applications and ships with a mount kit, with injection-molded bracket covers on some applications. The black powder coat over e-coated steel is covered for three years; if you want the lifetime warranty, Westin's polished stainless SuperCab number is 21-53930. Westin lists the PRO TRAXX 5 line at $297 to $820 across all applications and does not print a price for this number, so check the listing. If you prefer a slimmer tube, Westin's PRO TRAXX 4 SuperCab bar, 21-23935, is in our product list.

Rough Country's HD2 is the pick for a truck that spends winters on salted roads. Rough Country describes it as a durable one-piece aluminum build, strong, lightweight and corrosion-resistant, with cab-length coverage, and lists the SRB151791 for the 2015–2026 F-150, the 2017–2026 Raptor and Super Duty, and the later Tremor and Lightning, Crew Cab only. The Amazon title names the 2015–2025 F-150, Lightning, Super Duty and Raptor Crew Cab with a 5 in wide non-slip step.

Rough Country lists it at $379.95, $70 less than the RPT2, and backs it with the same limited lifetime warranty against material and workmanship failures, including welds, brackets and structural components, for the original purchaser, with the finish covered for one year. The install is described as hassle-free bolt-on with no drilling, and Rough Country posts a five-minute install video on the page. What you give up against the RPT2 is step width: Rough Country does not print a width for the HD2, and the listing title says 5 in, against the RPT2's 6.75 in. Aluminum also dents more easily than steel if a board takes a hit. For a daily-driven SuperCrew where rust is the enemy, it is the better long-term buy.

The BA2 is Rough Country's plainer steel board, and it costs the same as the HD2. Rough Country lists the 41010 for the 2015–2026 F-150, 2017–2026 Raptor and Super Duty, Crew Cab models only, with heavy-duty steel construction and a wide 5 in stepping area. The Amazon listing title names the 2015–2023 F-150 Crew Cab with a wide 5 in non-slip step, which covers every year of this generation.

The reason to pick it over the RPT2 is the warranty structure. The BA2 carries a 5-year limited warranty, and Rough Country's page does not split out a shorter finish term the way the RPT2 and HD2 pages do, which makes it the Rough Country board with the longest stated coverage on the coating. The reason to pick the RPT2 instead is step width, 6.75 in against 5 in. Rough Country lists the BA2 at $379.95 with free shipping, and describes a no-drill, direct bolt-on install. It does not publish a load rating, weight or finish type, so ask the seller if any of those matter to you. For an XLT SuperCrew that needs a solid step without a premium look, it is the value buy.
