This belt drive will keep your timing a whole lot more stable vs the std. single or double chain arrangement. You can also degree your cam with the screw adjustment built in. It is amazing how quiet your engine will be by using a belt instead of chain. This kit comes complete, mounting housing, seals, bolts, gears, gasket and of course the belt.
This setup is not legal for SCCA racing in production classes. Great for GT classes and hot street use.
