Jeep JK Rock Sliders 07-Pres Wrangler JK Unlimited 4 DR Adventure TNT Customs. Rocker guards, sliders for your Jeep Wrangler JK 4 Door Unlimited with a step! TNT, Inc. Jeep JK Wrangler 4 Door Unlimited Adventure Series Sliders feature rugged construction and sleek styling giving our sliders a one-two punch. Our rocker guards are constructed of 3/16 inch plate steel and 2X2X .188 inch square tubing. Sliders mount to the three center body mounts using rugged mounting brackets that distribute the potential loads evenly across the frame. The Jeep JK's rocker panel has very little structure behind it so our rock rails mount to the frame only. Our steps not only provide added protection but with their additional width and double row dimpled panel they make getting in and out of your rig and accessing rooftop cargo even easier. These sliders ship bare steel.
