The Mark Williams 1350 Series U-Joint Precision is a heavy-duty universal joint engineered for high-torque driveline applications where reliability and precision alignment are non-negotiable. Designed with a 1-3/16 inch cap diameter and 3-5/8 inch across-flats dimension, this 1350 series u-joint delivers the strength required in off-road recovery, performance automotive builds, and industrial drive systems where extreme loads demand premium component quality and exact tolerances.
Built from solid steel in natural finish, this precision u-joint is manufactured to tight tolerances that minimize driveline vibration and binding under load. The 1350 series designation indicates this joint is rated for substantial torque capacity, making it the choice for applications involving lifted vehicles, winch-equipped trucks, or high-horsepower engine conversions. The precision construction ensures smooth power transfer while reducing stress on transmission, transfer case, and axle components. At 2.57 lbs, the joint delivers substantial structural integrity without unnecessary weight penalty, critical in systems where every component must perform at its absolute limit.
Technicians and builders turn to Mark Williams 1350 series u-joints when original equipment won't handle upgraded engine output or when driveline reinforcement is part of a comprehensive build. Whether you're restoring a classic with modern performance upgrades, fabricating a competition-grade off-road platform, or engineering industrial machinery requiring dual-shaft coupling, the precision tolerances and heavy-duty steel construction of this universal joint ensure years of trouble-free operation under demanding conditions.
The 1350 series represents Mark Williams' mid-to-upper tier u-joint offering, positioned between entry-level 1310 series components and maximum-capacity 1480 series units. This sizing makes it ideal for serious street and off-road builds where the jump to 1480 capacity isn't required but standard 1310 components are outmatched. Sold individually, each joint comes ready to install—verify spline and cap compatibility with your existing driveshaft and yoke configuration before ordering.
