Premium Powered Running Boards by AMP

When you’ve lifted your truck, getting in and out shouldn’t feel like climbing a ladder. That’s where the AMP Research PowerStep XL comes in. Built specifically for higher trucks like the Silverado and Sierra HD, this setup gives you an extra 3 inches of drop compared to the standard PowerStep, making entry and exit a whole lot easier, without compromising on looks or ground clearance. Integrated LED lights light up the step area at night, which not only adds style but also helps with visibility. Whether you’re loading up for work or heading out on a trail run, the PowerStep XL is the kind of upgrade that brings real-world functionality to your lifted truck.

High-Quality Construction

These electric-powered running boards automatically deploy the moment you open a door, then tuck themselves back up when the doors close. It's a clean, factory-style appearance when you’re on the move and serious convenience when you're getting in or out. AMP designed the XL with rugged conditions in mind. Each board is built from die-cast aluminum alloy and coated in a textured black powder finish that holds up to weather, corrosion, and everyday abuse. They’re rated to handle 600 pounds per side, so you can count on them no matter how you load up.
