Shaft 3/4 DD - 36in

The IDIDIT Shaft 3/4 DD 36-inch steering shaft is a precision-engineered component designed for custom steering system builds and restoration projects requiring a universal-fit intermediate steering shaft. This 36-inch steel shaft features a 3/4-inch double-D bore on both ends, providing secure mechanical coupling to both steering column input and steering box output without reliance on set screws or adhesives. The natural finish steel construction delivers straightforward durability without cosmetic coating, making it suitable for applications where functional reliability takes priority over appearance.

At 3.8 pounds and measuring 0.75 inches in diameter with a 36-inch overall length, this shaft accommodates typical steering geometry in street rods, custom vehicles, and retrofit installations where stock steering column length or angle does not match the steering box centerline. The double-D profile on both ends ensures positive drive engagement without rotational slip—a critical requirement in steering systems where even minor backlash can affect steering response and vehicle control. The 36-inch length positions this shaft as an intermediate component, suitable for setups requiring additional length between a collapsible steering column and a remote steering box location.

This shaft is intended for builders and fabricators working on custom steering installations, classic car restorations, and off-road vehicle builds where steering components must be tailored to non-standard frame and chassis layouts. Proper installation requires confirming that both connection points—steering column stub and steering box input—feature matching 3/4-inch double-D bores, and that the 36-inch length bridges the distance between these points without binding or excessive vibration. Steering shafts operate under constant rotational and torsional stress during vehicle operation, making fit and alignment critical to safe steering performance.
