Double D Shaft 3/4in DD x 18in Long

The BORGESON Double D Shaft 3/4in DD x 18in Long is a precision-engineered steering component ideal for custom vehicle builds and restoration projects that require modifications to steering geometry. This double-D shaft acts as an intermediate coupling between the steering box and column, enabling builders to relocate or reconfigure steering systems while maintaining input torque transfer and responsiveness.

Constructed from high-strength steel, the BORGESON shaft features dual D-shaped bores (3/4in diameter) on each end, ensuring a positive, slip-free engagement with square D-shaped steering components under load. The 18-inch length is designed to accommodate mid-mount engine swaps, transmission relocations, or custom chassis layouts where standard steering columns may not align with the steering box input. The precision-machined D-bore geometry guarantees a consistent fit across quality aftermarket and OEM steering components, reducing wobble and runout that could affect steering feel.

Custom fabricators, restoration shops, and automotive enthusiasts engaged in building tube-frame vehicles or executing extensive engine bay modifications rely on BORGESON shafts to ensure steering precision and reliability. This product is essential for anyone looking to adapt factory or aftermarket steering columns to non-standard mounting positions, making it a versatile choice for various automotive applications.
