Looking for performance on and off the trail? Weve got you covered. Whether you call them rock sliders, rock rails, nerf bars or rocker protectors, there are a few features you need to have.  The first is obviously protection. ACE Rock Sliders are made with beefy 2 mild steel tubing, with a super-strong 0.134 thickness. Thats some serious protection for your rocker panels. The next big thing is function. ACE Rock Sliders shine here as well. Designed with just the right angle to protect up into the side of the rocker panel, ACE Sliders wont get you hung-up when the trail gets dicey. Plus they work great as a step into your Jeep, hanging off the body just enough to get a good foothold.
