Steering U-Joint 1in-48 x 3/4in DD

The Steering U-Joint 1in-48 x 3/4in DD from BORGESON is a precision universal joint engineered for reliable steering column connections in custom vehicles, hot rods, and classic car restorations. This single-joint design accommodates the most common steering shaft configurations, bridging a 1-inch 48-spline input to a 3/4-inch double-D output. Whether you're assembling a custom steering system or replacing a worn OEM joint, this universal joint handles the angular misalignment and torque transfer that occurs between the steering wheel and steering box.

Constructed from durable steel and finished in natural (uncoated) form, the Steering U-Joint 1in-48 x 3/4in DD distributes rotational forces smoothly across its bearing assembly, minimizing binding and vibration during turns. The 1-inch 48-spline connection provides a secure, indexed fit that resists slippage under steering load, while the 3/4-inch double-D output accommodates standard steering box input shafts found on many domestic platforms. The steel construction ensures long service life in both street and low-speed off-road applications, with minimal maintenance required beyond periodic inspection for wear.

Fabricators, restoration shops, and custom vehicle builders rely on BORGESON universal joints for their reputation for precision fitment and durability. This component is ideal for non-power steering conversions, manual steering system builds, and any application requiring a reliable intermediate joint between steering column and steering gearbox. Installation is straightforward—simply align the spline teeth and secure both connections; no special tools or modifications are required. Verify your steering shaft spline count and output diameter before ordering to ensure proper fit with your specific application.
