Universal Joint S44 to 1310 Series OSR/ISR

The Universal Joint S44 to 1310 Series OSR/ISR is a critical driveline component engineered for builders and mechanics who demand reliability in custom drivetrain setups. This DANA-SPICER joint bridges the gap between older S44 spline configurations and modern 1310 series yokes, making it essential for engine swaps, transmission upgrades, and frame-off restorations.

Manufactured by DANA-SPICER, the industry standard for driveline components, this joint features a robust cross-and-bearing design that handles torque loads while allowing the articulation needed for suspension travel and angle correction in lifted trucks, lowered cars, and competition vehicles. Weighing just 1.24 lbs with compact dimensions (3.55 x 1.35 x 3.65 inches), it integrates seamlessly into tight fabrication spaces without sacrificing strength or performance.

This joint is ideal for technicians upgrading legacy drivetrains or engineering adapter solutions. Its hardened alloy construction resists spline wear and fretting, ensuring longevity when operating at high RPM or under load-induced stress. Whether you're fabricating a custom hot rod or repairing a worn driveshaft assembly, this universal joint delivers the durability required for safe, efficient power transfer.
