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.

Constructed from solid steel in a natural finish, the Steering Coupler 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.

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 verified weight of 0.83 lbs ensure reliable torque transfer and steering response without play or slippage.
