You are looking at a 9 piece set of chrome billet grooved spike frame and axle caps. This set consists of 9 grooved spike caps and 4 threaded rods, already cut to the length it needs to be so they can be installed easily. Loctite is also included. The threaded rod that goes through the rear axle has a slotted hole so the axle nut pin can still be used. This kit will cover all holes in the frame and front and rear wheel axles. Kit installs in less than 15 minutes. Fits: '99-'08 Hayabusa
