New JK Rock Slider Steps!! CNC cut and formed in house out of 3/16" steel for excellent fitment and durabilty in the rocks. Drilling of the tub is required for installation of our 5/16" nutserts (tool included). Mounts via nutserts in the tub and the body mount bolts underneath the Jeep (3 in the 4 door, 2 in the 2 door). The step is lightened and strengthened simultaneously by 2 different types of dimples and 8 ribs. The facet towards the rocks is a 1.5" dimpled hole and the top facet or the step has 1" grimples. The grimples provide strength for the step and grip for your feet. The dimpled holes on two planes as well as small drainage holes on the bottom makes it very easy to hose out mud and trail debris.
