Description
Swapping a TKO or TKX five-speed into your '56-'62 Corvette means dealing with a transmission output that's nothing like the original powerglide or three-speed manual. Both the TKO and TKX feature a 31-spline output shaft, requiring a properly matched slip yoke and purpose-built driveshaft to handle the transmission's 600 lb-ft torque capacity while fitting the C1's notoriously tight tunnel and low ground clearance.
This steel driveshaft solves the conversion challenge with a 31-spline forged steel slip yoke featuring removable caps for straightforward installation and future service access. The 2.5" diameter steel tube strikes the ideal balance between strength and clearance - critical in first-generation Corvettes where every fraction of an inch matters. The 1310-series rear U-joint (1.062" cap diameter, 3.219" span) provides reliable power transfer while maintaining compatibility with most differential yoke configurations found in C1 Corvettes.
Every driveshaft is professionally built using the latest manufacturing technologies and high-speed balanced to eliminate vibration throughout the RPM range. Unlike off-the-shelf universal shafts, this driveshaft is custom-built to your vehicle's exact measurements after you complete the transmission installation - ensuring precise length and proper operating angles for your specific combination.
This is an application-specific driveshaft requiring custom measurements from your completed TKO/TKX conversion. Submit the completed Driveshaft Build Sheet form to info@moderndriveline.com after your transmission is installed. Made in the USA with lifetime technical support from MDL's drivetrain specialists.
