Steering U-Joint 3/4in-30 x 3/4in Smooth

The Steering U-Joint 3/4in-30 x 3/4in Smooth by BORGESON is a precision universal joint engineered to connect steering column shafts with different spline configurations in custom and modified vehicles. This component is essential for builders and mechanics who are upgrading or fabricating steering systems that demand flexibility between incompatible shaft diameters or spline patterns. Whether you're installing an aftermarket steering box, lengthening a steering column for a chassis swap, or adapting a modern steering system to a classic car, this u-joint bridges the gap between mismatched components with proven durability.

Constructed from high-strength steel in natural finish, the Steering U-Joint features a 3/4-inch, 30-spline input end paired with a 3/4-inch smooth output shaft, allowing seamless integration with both splined and non-splined steering components. The universal joint design permits angular misalignment between input and output shafts—critical when steering columns are mounted at an angle or when the steering box sits at a different height than the steering wheel shaft. BORGESON's engineering ensures smooth power transfer without binding, vibration, or wear, qualities that enthusiasts and professional builders rely on for responsive steering feel and long-term reliability in high-performance and custom applications.

This universal joint is ideal for fabricators performing frame-off restorations, street rod builds, or off-road vehicle modifications where steering column routing demands flexibility. It works with any steering box or intermediate shaft that accepts a 3/4-inch, 30-spline male input and outputs to a 3/4-inch smooth bore shaft or component. Installation requires basic mechanical skill and standard hand tools; ensure both connection points are properly supported and aligned to prevent premature wear. The compact 5.75-inch length and lightweight 0.84-pound construction minimize installation clearance issues while maintaining the structural integrity necessary for safe steering operation under all driving conditions.
