Combining functionality, strength, protection and a visually unique design, ARB has developed an ARB style of Rock Slider, not previously available for the Jeep platform. ARB Rock Sliders to suit the Jeep Wrangler JL 4 - door are made up of both the slider assembly and a lower body mount to spread the load and protect the vulnerable lower - rocker area of the JL when used off road. (Note, due to slight differences in flare design between the Sport model and the Rubicon, there is reduced clearance between the JL Sport flare and the rock slider.)
