99T Magnesium Bellhousing Kits with Ultra 5.5 Clutch were engineered specifically to provide a combination of the lightest weight bellhousing and lowest weight & inertia 6-leg 5.5 Ultra clutch for the most demanding short track racers.
The lightweight and rigid magnesium bellhousing provides maximum ground clearance and features an easy access side-bolt mounting system for the starter. Unlike other bellhousings on the market, the transmission no longer has to be removed in order to service the starter. The lightweight and 5.5 ULTRA clutch and small diameter 99-tooth cover-mount ring gear provides an ultra-low inertia and maximum reliability.
