Description
Converting your 1968-1982 C3 Corvette to a TREMEC TKO or TKX transmission demands a purpose-built driveshaft engineered for modern 5-speed output characteristics. Factory Corvette driveshafts won't work - the TKO and TKX use a 31-spline output shaft that requires a matching slip yoke, and the transmission's different overall length and mounting position mean your driveshaft length changes entirely.
This steel driveshaft solves the conversion driveline puzzle. The forged steel removable slip yoke features 31 splines that engage directly with TREMEC TKO and TKX output shafts for a high-strength connection capable of handling serious torque. The 1310 series rear U-joint provides the ideal balance of strength and compact dimensions for C3 tunnel clearance - its 1.062-inch cap diameter and 3.219-inch width deliver reliable power transfer without interference.
Steel tube construction with a 2.0-inch diameter delivers the torsional stiffness required for high-RPM operation while maintaining compatibility with C3 chassis constraints. Every driveshaft is professionally balanced at high speed to eliminate vibration and finished in black for corrosion resistance. The result is a smooth, strong connection between your modern transmission and factory rear differential.
This is a custom-built component requiring specific measurements from your completed installation. Transmission position, rear differential setup, and any chassis modifications all affect final driveshaft length and pinion angle requirements. Submit the completed driveshaft measurement form to info@moderndriveline.com so MDL can build your shaft to exact specifications. Made in the USA.
