Steering Coupler 11/16-36 X 3/4 Smooth

The Borgeson Steering Coupler 11/16-36 X 3/4 Smooth is a universal weld-on steering shaft coupling engineered for classic and custom vehicle builds where steering column alignment and vibration isolation are critical. This coupler bridges misaligned or incompatible steering shafts by connecting a 11/16-inch 36-spline input to a 3/4-inch smooth output, making it an essential component for hot rod, street rod, and restoration projects that demand reliable steering response and durability.

Constructed from solid steel and finished in a natural protective coating, this coupler is designed for permanent installation via welding, ensuring zero play and maximum power transmission integrity. The 36-spline to smooth shaft transition allows flexing and misalignment compensation while maintaining precise steering feel—a critical feature when adapting aftermarket steering columns or vintage gear boxes to modern steering racks. The compact footprint (3.7 x 1.55 x 5.25 inches) and lightweight design (0.27 lbs) minimize steering column obstruction and inertia, contributing to responsive handling characteristics in performance-oriented applications.

This universal coupler is ideal for fabricators, custom builders, and enthusiasts performing shaft-to-shaft steering conversions where standard couplers do not accommodate the specific spline and diameter combination required. Installation requires professional welding to secure the coupler onto existing steering shafts; proper alignment before welding ensures smooth operation and prevents premature wear. Compatible with any steering system where shaft sizes and spline counts match the specified dimensions, this Borgeson component delivers the engineering precision expected from a trusted supplier of steering and suspension components for the automotive aftermarket.
