Steering Universal Joint Steel 1DD X 13/16-36

The Borgeson Steering Universal Joint Steel 1DD X 13/16-36 (Part #015240) is a single-joint universal coupling designed to connect steering components with different shaft sizes and spline configurations. This steel universal joint couples a 1-inch double-D shaft to a 13/16-inch 36-spline shaft, making it ideal for custom steering system installations where shaft misalignment or angle changes must be accommodated without binding or excessive wear.

The joint features a hardened steel construction with a natural finish, delivering the durability required in steering applications where precision and reliability are critical. The 1-inch double-D connection provides a positive, keyed interface that resists slipping under load, while the 13/16-inch 36-spline end accommodates standard steering column and intermediate shaft profiles. Weighing 0.95 lbs and compact at 3.6 x 1.6 x 5.6 inches, this joint is engineered to handle the torque and angular deflection typical of performance vehicle steering systems without introducing play or vibration into the steering path.

This universal joint is suited for hot rod builders, custom vehicle fabricators, and enthusiasts restoring or modifying steering systems where off-the-shelf shafts don't align properly. It's commonly specified in applications requiring flexible shaft coupling at angles up to 15 degrees, allowing the steering column to be repositioned or angled without compromising response. The steel construction and verified spline counts ensure compatibility with aftermarket steering columns and OEM replacement shafts across a range of classic and modern platforms.
