1310 Slip Yoke

The Richmond 1310 Slip Yoke is a 32-spline steel component engineered for driveshaft assemblies used with TH400 transmissions and 1310-series U-joints. This slip yoke serves as the critical interface between the transmission output shaft and the driveshaft, accommodating axial movement during suspension compression and extension while maintaining smooth torque delivery to the rear axle. Built from solid steel in a natural finish, it provides the durability and precision fit required for both street and high-performance applications.

The 32-spline configuration is the industry standard for 1310 U-joint compatibility, ensuring proper engagement with TH400 transmission output shafts. The slip yoke's design allows the driveshaft to lengthen and shorten as the suspension articulates, preventing binding and extending component life. At 2.55 lbs and compact dimensions (3.95 x 2.75 x 8.3 inches), this yoke integrates seamlessly into existing driveline assemblies without requiring modifications. The natural steel finish requires standard corrosion protection measures typical of automotive drivetrain components in outdoor or salt-exposed environments.

This component is essential for street rods, classic car restorations, muscle cars, and custom builds using TH400 automatic transmissions paired with 1310 driveshaft assemblies. Builders and mechanics working on rear-wheel-drive platforms—whether for daily driving, weekend cruising, or performance use—rely on properly matched slip yokes to ensure reliable driveline operation. Replacement becomes necessary when existing yokes show wear, spline damage, or when upgrading to a fresh driveshaft assembly. The Richmond brand slip yoke delivers OEM-quality fitment and proven reliability in the automotive restoration and custom build community.
