4-Speed Clutch For Splined Mainshaft
You know the sad story. The torque on the clutch nut backs off a hair and the key on the transmission mainshaft shears off. This usually happens at the most inconvenient time and place. And the probability of this sad story playing out is greater with performance applications.
The splined Shovel clutch kit retrofits and upgrades the stock tapered mainshaft and clutch to a modern 18 tooth spline configuration. Kit includes a fully assembled clutch and splined 4-speed mainshaft to retrofit stock 1970-E84 Big Twins.
The clutch is based off of our 9-plate clutch used on 1990-2006 applications and fits in the stock Shovelhead primary housing and TTP. We offer 35, 36, 37, and 38 tooth clutch sprockets with our clutches to dial in your overall gear ratio. 18 tooth mainshaft installs into the stock 4-speed transmission just like stock.
