Our new NM2-V2 rear bumper is a 4 piece set. The bottom skid mounts to chassis at six locations; four at supplied stainless steel standoffs and two at the rear skid plate mounts. We have added a hefty Delrin block that is mounted to the rear bulkhead for extra mounting points on the bumper. You can still run your rear sway bar set up as well. Included with this set is a rear brace that mounts to your Wing mount and floats on our rear bumper. This V2 bumper is compatible with our Chassis Skid and our Y077 Wheelie Bar.
