Steering U-Joint 3/4in Smooth X 3/4in Smooth

The Borgeson Steering U-Joint 3/4in Smooth X 3/4in Smooth is a single universal joint designed to connect steering components with matching 3/4-inch smooth bore shafts. Built from steel with a natural finish, this steering universal joint provides reliable articulation for custom steering systems, classic vehicle restorations, and high-performance steering linkages where shaft misalignment or angle changes require smooth, backlash-free motion transfer.

Universal joints in steering systems must handle both rotational torque and angular deflection while maintaining precision. The 3/4-inch smooth bore configuration on both ends allows for direct shaft insertion and typically uses set screws or splines for positive engagement. Steel construction provides the strength necessary to transmit steering input without flex or wear, while the single-joint design keeps the package compact for tight engine bays or modified steering columns. This component weighs 0.81 lbs and measures 3.75 x 1.7 x 5.3 inches, making it suitable for custom fabrication and retrofit applications where space and weight are considerations.

Steering universal joints are essential for vehicles with modified or extended steering columns, custom hot rods, off-road builds, and classic car restorations where original steering geometry no longer applies. The 3/4-inch smooth bore standard is common in aftermarket steering applications and street rod builds. Installers should verify shaft bore diameter, set screw sizing, and the angle range required before installation to ensure proper fit and function. Borgeson is a well-established manufacturer of steering components and has earned recognition for producing parts that meet the demands of custom builders and restoration specialists.

When selecting a steering u-joint, bore diameter match is critical—both shafts must be 3/4 inch for this model. Smooth bores require positive locking via set screw or similar retention method. For vehicles experiencing steering play or vibration after column modification, a quality universal joint isolates angle misalignment and reduces transmitted vibration to the steering wheel, improving drivability and control feel in custom applications.
