AMP Research PowerStep XL for GMC Sierra 2500HD/3500HD (2024–2026) 77255-01A Extra-Low Powered Steps for Big Truck Confidence
If you’ve ever climbed into a Sierra HD and felt that first step stretch your knee a bit too far, the AMP Research PowerStep XL is exactly what your truck’s been waiting on. Designed specifically for the added height of the 2500HD and 3500HD, these AMP Research PowerStep XL running boards drop a full three inches lower than the standard PowerStep, making entry feel natural instead of like a hop. They tuck up tight against the rocker panel while you are driving, then swing out on their own the moment you open the door. It is a clean, smart design that really earns its keep, especially after a long day on the job or when the truck is loaded down and you need all the help you can get climbing in and out.
Arm Your Sierra with Extra-Low AMP Research PowerStep XL Running Boards!
- Easier Access for Lifted or Stock HD Trucks– That extra drop makes climbing smoother, whether you’re headed to work or hauling the family.
- Automatic Deploy and Retract– No flipping of switches required, no thinking necessary, just open the door and the step will be right there where you need it.
- Built to Handle Real Weight– Marine-grade aluminum rails and stainless steel pivot pins will hold up to 600 pounds without bending.
- Ready for Any Weather– Self-lubricating bushings and corrosion-resistant coatings ensure that everything keeps moving, even when the weather doesn’t.
- Better Night time Footing– Built-in LED lights illuminate the area around the step so you’re never left wondering where to put your foot.
