Amp Research PowerStep XL Running Boards are automated boards extend when your cab door is opened and tuck away when the door is shut. The extending and retracting happens quickly - in less than a second - so you're not waiting around.
These differ from the original Powerstep model in that they hang 3" lower and have an integrated custom rocker rail. This makes these boards perfect for lifted trucks.
The AMP PowerStep XL is made from corrosion resistant aluminum-alloy which makes it light weight and high strength. They have a load capacity of 600 lbs on each board which means they are able to hold up to anyone getting in and out of your vehicle.
These boards are made in the USA and backed by a 5 year warranty.
