SRJL-21 2018+ Jeep JL 2 Door Boatside Rock Sliders. The DV8 Offroad SRJL-21 was designed for ultimate protection for those who use their sliders regularly while traversing trails. These sliders bolt directly to the frame and utilize the frame to body mounts along with the frame rails themselves to add rigidity and reduce deflection to near zero. They can be run as a regular slider or can be used with the included plates to create a mini boatside effect. These plates help the Jeep to slide off of obstacles rather than getting hung up. Install is simple and 100 percent bolt on so the sliders can be removed for touch up or recoating
