About this kit
AC2 Lighted Running Boards, fitment-checked
Rough Country 57003 is a pair of AC2 lighted running boards for 2007-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks in crew cab configuration only. The kit pairs a black lighted step board set with a crew-cab-specific black bracket kit, and the integrated LED strip switches between amber and white output.
These AC2 running boards fit 2007-2018 Silverado 1500 and Sierra 1500 crew cab trucks — regular and extended cab configurations are not covered, so confirm your cab before ordering. Fitment spans 4WD, AWD, and RWD applications across WT, LT, LTZ, SLE, SLT, Denali, and High Country trims listed in the fitment section. The one-piece steel boards carry a black powder-coated finish and bolt on with hand tools; no drilling or cutting is called for. An internal switch selects amber or white LED output, and a magnetic sensor triggers the lights when a door opens. Rough Country lists installation at 3-4 hours.
