Double D Steering Shaft 60in x 3/4in

The Double D Steering Shaft 60in x 3/4in from ALLSTAR PERFORMANCE is a critical component for custom steering system builds, hot rods, and modified vehicles where factory steering geometry requires replacement or extension. Fabricators and restoration shops rely on this shaft to bridge the distance between the steering box output and the intermediate steering column, especially in frame-off restorations, engine swaps, and street rod applications where standard components won't fit the modified layout. This universal steering shaft accommodates custom chassis work and non-traditional engine placements that demand flexible steering solutions.

Constructed as a solid shaft with double D cross-sections at both ends, this 60-inch shaft provides robust torque transmission while maintaining concentricity required for smooth, responsive steering feel. The 3/4-inch diameter offers substantial rigidity to eliminate deflection and binding under hard cornering loads, while the double D profile (a square-like slot design) ensures positive mechanical coupling at both the gearbox and column interfaces without relying on splines that can wear loose over time. At 6.5 lbs, the shaft remains light enough for manual steering systems while delivering the strength needed for modern power steering retrofits on vintage platforms.

Mechanics and fabricators building tube-frame street rods, classic muscle car restorations, and drag vehicles benefit from the adjustable length this shaft provides—the 60-inch dimension accommodates most mid-engine and rear-engine conversions where steering box relocation is necessary. Installation requires double D adapter couplings at each end and proper shaft support bearings to prevent vibration and ensure predictable on-center feel. Verify your steering box output and steering column input profiles are double D compatible, and plan for intermediate u-joint support if the shaft spans more than typical steering column heights.
