Steering U-Joint 1in DD x 11/16-36

The Steering U-Joint 1in DD x 11/16-36 from Borgeson is a precision universal joint engineered to connect steering shafts with different input and output spline configurations in custom and modified vehicles. This single-joint design bridges the gap between a 1-inch double-D input shaft and an 11/16-inch 36-spline output shaft, making it essential for builders who need flexible steering geometry when fabricating custom steering columns or installing aftermarket steering boxes.

Constructed from durable steel in a natural finish, this universal joint accommodates angular misalignment between steering components while maintaining smooth torque transfer under road loads. The dual-diameter 1-inch double-D spline provides a secure, positive connection that resists rotational slip—critical when steering feedback and driver control are non-negotiable. The 11/16-inch 36-spline output accepts modern aftermarket steering boxes and intermediate shafts common in performance and restomod applications. Weighing just 1.02 pounds, the compact 3.7 x 1.75 x 5.6-inch package installs cleanly in tight engine bays without requiring extensive modification to surrounding components.

This joint benefits mechanics and fabricators tackling street rods, vintage truck restorations, and performance vehicle builds where factory steering geometry doesn't align with new frame rails or engine positioning. Its versatility makes it ideal for buyers adapting modern steering systems to classic platforms or custom-fabricating offset steering arrangements that demand precise angular correction. Installation requires only basic hand tools and a clean workspace; proper alignment of both spline ends ensures long-term reliability and consistent steering response during acceleration, braking, and cornering maneuvers.
