Tilton is proud to introduce its latest generation of bellhousing kits.  Tilton 99T 5.5 Bellhousing Kits were engineered specifically to meets the demands of short track racing.  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 5.5 ULTRA clutch and small diameter 99-tooth cover-mount ring gear provides an ultra-low inertia and maximum reliability.  Since 1972, Tilton has been supplying championship winning parts to racers and these new 99T 5.5 Bellhousing Kits are destined to become the new standard in short track racing.
