ARB Rock Sliders to suit the Ford Bronco 4-door are a one-piece design to spread the load and protect the vulnerable lower sill area of the vehicle when used off-road. The multi-folded sliders are directly mounted to the vehicle chassis rail and do not restrict ramp over angle. ARB Rock Sliders are manufactured from multi-folded, 4mm laser cut, folded and pulse welded sheet steel to provide strength without the need for thicker material to keep weight at a minimum. To complement the ARB Bronco protection equipment range, the Rock Sliders are finished in Integrit? textured black powder coat.
