15T clutchbell manufactured on a precision manual gear machine from HUDY Gear Steel – a material specially formulated and developed for use in gears. Heat treated for highest strength, minimal wear and extra-long lifespan. The clutchbell features unique oversized ball-bearings designed and engineered by XRAY. Replacing the standard 5x10 bearings with 1.3mm balls, the oversized clutch bearings are 5x12 with 2.0mm balls and extra-thick bearing walls. This translates to higher load-carrying capabilities which will increase the life of the bearings and reduce the risk of clutch bearing failure during long final runs. The bearings come with special high-temperature resistant grease to ensure proper lubrication during high-revving engine operations and long runs. Clutchbells are available in sizes of 15T, 16T, 17T and 18T.
