Our Rock Sliders have been proven to hold up to extreme conditions. Whether adding a layer of protection on the road or assisting you on the trail, rest assured your ARTwerx Fab products will show up for the challenge. We use .1875 wall thickness 2” main rail for rigid strength and .120” wall for the kicker. We add in 2” struts at 24” intervals for added strength to the kicker. This combination has withstood impacts at 40mph with no damage to sliders. These are made to order using exact measurements taken from your vehicle and built to your desires.
