About this kit
Power Running Boards, fitment-checked
Deployable power running boards for 2014–2019 Chevy Silverado and GMC Sierra crew cabs (Rough Country PSR51518), covering 1500, 2500 HD, and 3500 HD gas trucks. An 83-inch power rail step with dual motors, LED lighting, and 660 lb capacity per side.
This set fits 4-door crew cab configurations only, across 2014–2018 Silverado and Sierra 1500 and 2015–2019 2500 HD and 3500 HD trucks — gas engines only, and not trucks with a DEF tank. The kit pairs an 83-inch power rail step with a cab mounting kit. Each 6-inch aluminum board deploys on dual motors built for extreme climates, carries 660 lb, and lights the step with integrated LEDs; SAFE-STOP halts the board on blockage and an interior switch gives manual override. Installation is no-drill, and a downloadable installation guide is available.
