Steering Coupler Steel 3 /4-36 X 3/4DD

The Steering Coupler Steel 3/4-36 X 3/4DD by Borgeson is a precision engineered coupling designed to connect steering shafts in custom vehicles and restoration projects where shaft misalignment or length adjustment is necessary. This component serves as the critical link between a steering column and steering gearbox, accommodating both splined and double-D shaft configurations. Whether you're building a custom hot rod, restoring a classic vehicle, or engineering a specialty application, this steel coupler ensures reliable torque transfer and steering response without play or slippage.

Constructed from solid steel in natural finish, the Steering Coupler Steel 3/4-36 X 3/4DD features a 3/4-inch 36-spline connection on one end and a 3/4-inch double-D (DD) bore on the other, making it compatible with both standard splined steering shafts and steering boxes with double-D inputs. The dual-bore design eliminates the need for additional adapters, simplifying installation while maintaining concentricity and alignment. Steel construction provides superior rigidity and heat resistance compared to aluminum alternatives, ensuring consistent steering feel and longevity even under heavy use or high-performance driving conditions.

This coupler is ideal for fabricators, restorers, and enthusiasts building or modifying vehicles with custom steering geometries, including street rods, muscle cars, off-road trucks, and vintage restorations. Its compact dimensions and moderate weight of 0.83 lbs make it easy to integrate into tight engine compartments. Installation typically involves sliding the coupler onto both shaft ends and securing with set screws; proper alignment during fitment is critical to avoid vibration and ensure safe steering operation. Borgeson's reputation for steering components makes this coupling a trusted choice for builders prioritizing reliability and precision in critical steering systems.
