This kit replaces the OEM sheet metal screws with threaded bosses and hardware with a built in lock washer for 2003-2017 Gen III, IV, and V Vipers. The optional kit also replaces the same sheet metal screws used for the rear wheel liner on the Gen V.
Stainless steel / black oxide construction.
The kit includes a drill bit to slightly enlarge the hole and a threaded tap so the boss can be threaded into the frame.
