U-Joint Girdles - 1350 Series

The MOROSO U-Joint Girdles 1350 Series (MPN 85830) are aluminum race yoke components engineered for high-performance driveline applications requiring precision u-joint support. Designed with 1.668-inch bolt centers and 1-3/16-inch diameter caps, these black anodized girdles stabilize u-joint assemblies in demanding motorsport and heavy-duty off-road environments where lateral loads and vibration can compromise joint integrity. The 1350 Series rating indicates suitability for applications up to that torque capacity, making them compatible with Ford 8.8 and 9-inch rear axles commonly found in performance and restoration builds.

Aluminum construction provides weight savings over cast iron while the black anodized finish resists corrosion in harsh environments—critical for vehicles exposed to moisture, salt air, or prolonged storage. The 1.668-inch bolt center spacing and 1-3/16-inch cap diameter are industry-standard dimensions that ensure compatibility with OEM and aftermarket u-joint assemblies designed for 1350 series driveshaft systems. Proper girdle installation reduces unwanted u-joint deflection under load, which translates to smoother power delivery and extended component life in high-stress conditions. This is a complete kit, simplifying installation for builders and technicians.

U-joint girdles appeal to performance enthusiasts rebuilding or upgrading Ford 8.8 and 9-inch differentials, hot rod builders, off-road truck owners, and motorsport competitors who demand durability and precision. The 1350 series rating fits mid-level performance platforms—more capable than stock but not extreme-duty race builds. Operators familiar with driveline assembly will recognize MOROSO's positioning as a reliable source for drivetrain components, though these girdles require proper installation and a working understanding of u-joint mechanics for optimal performance.
