Check your truck: Match your year and model to the fitment table; some rows carry a cab, engine or trim limit (for example "Extended Cab / Crew Cab", "6.6L V8 Duramax engine only"), so check the note on your row. Your PowerStep kit number should be one of 75146-01A, 76147-01A, 76151-01A, 76152-01A and 5 more (all listed in the specs). Series: PowerStep.
Not for: where its row says so: the 5.0L V8 engine.
About AMP Research
AMP Research calls its PowerStep the original power-retractable running board, proven since 2002. A PowerStep deploys when a door opens and stows when the doors close.
Each set is built from parts that can be serviced one at a time: the running board (step) assemblies, the motor and idler linkages, the motors, the controller and the wire harness, with an OBD-II module on Plug-N-Play sets. AMP Research says replacement parts are specific to the vehicle make and model and to the PowerStep series installed, so every listing here names the kits it serves.
Authorized AMP Research dealer. Prestige Truck is an authorized AMP Research dealer, so what we sell is new and genuine AMP Research. Tell us your PowerStep part number or VIN before you order and we'll help you match the part.
