Steering Shaft 3/4in DD 36in Length

The HOLLEY Steering Shaft 3/4in Double D 36in Length (Part No. 320-201) is a universal steering component designed for custom hot rods, street rods, and specialty vehicles requiring a direct mechanical connection between the steering column and steering box. The 3/4-inch double-D profile provides a positive, non-slip fit into matching splined shafts, eliminating rotational play and ensuring precise steering response. This 36-inch length accommodates mid-to-long wheelbase applications while maintaining the rigidity necessary for accurate feedback to the driver.

Constructed from steel and finished in black zinc oxide, this shaft offers corrosion resistance and durability in both engine bay and interior environments. The double-D design—a flat-faced profile on opposing sides of the shaft—is the industry standard for steering applications because it distributes load evenly across contact surfaces and resists torque reversals that can occur during aggressive steering inputs or road shock. At 5 pounds, the shaft balances strength with the low unsprung weight preferred in performance builds. The 36-inch length is suitable for vehicles with steering boxes mounted at typical distances from the steering column, making this a popular choice for hot rod frame builders and restoration specialists.

This steering shaft is ideal for builders and restorers who demand OEM-level quality in steering linkage components. Mechanics working on custom chassis, vintage hot rods, and specialty vehicles rely on HOLLEY steering components to maintain precise control geometry. The universal fit and standard 3/4-inch double-D profile ensure compatibility across a broad range of aftermarket and original steering boxes. If your project requires a reliable, proven steering shaft that handles both street and performance driving, this HOLLEY component delivers the mechanical integrity required for safety-critical steering systems.
