1350 U-Joints for Heavy-Duty Driveline Builds

Our 1350 U-joints are built for Jeep, off-road, and high-performance applications that need more strength than stock joints can provide. The 1350 series uses a 1.188-inch cap diameter and 3.625-inch overall width, making it a common upgrade for demanding driveline setups that see higher torque and more suspension travel. JE Reel offers greaseable 1350 U-joints designed for serviceability and long-term use. This category is the right starting point when you are upgrading the core connection point in a stronger driveline.

1350 U-joints are a smart fit for lifted rigs, larger tires, and vehicles that operate under repeated shock load. They help reduce the chance of premature failure compared with smaller-series joints, especially in off-road and towing applications. For many builds, upgrading the U-joints is part of a complete 1350 conversion that also includes matching yokes, flanges, and driveshaft components. That gives you a stronger, more consistent driveline from end to end.

This also helps customers move through the catalog faster and improves internal linking across the 1350 product family. For builders who want reliability under load, the 1350 series is a proven upgrade path.
