RS1-M2 2021+ Bronco Zero Series Rock Sliders 2-Door Turn Offroad?s Zero Series rock sliders were designed and tested with heavy trail use in mind. These sliders provide maximum clearance and incredible protection when traversing obstacles. Their strength comes from the boxed ends, center supporting beams, and dimple dye reinforcing plates. Every slider features a 3-stage protective nano-textured powder coat and is dipped in an industrial primer prior to coating to protect the steel structure beneath. Design and R&D were focused on great clearance, maximum protection, and tight fitment while maintaining a simple, bolt-on installation.
