Steering U-Joint 3/4inDD x 5/8in-36

The Steering U-Joint 3/4inDD x 5/8in-36 from BORGESON (MPN 014918) is a precision steering universal joint engineered for vehicles that require a robust connection between misaligned steering shafts. Whether you're restoring a classic hot rod, building a custom street machine, or upgrading an off-road rig, this single-joint design bridges the gap between your steering column and intermediate shaft with proven reliability. Universal joints are essential components in any modified steering system where shaft angles or lengths don't align with OEM geometry.

Built from durable steel with a natural finish, this BORGESON u-joint features a 3/4-inch double-D bore on one end and a 5/8-inch 36-spline interface on the other, making it compatible with a wide range of steering shafts and gearbox inputs commonly found in custom automotive applications. The double-D connection provides excellent torque transfer and resists slipping under aggressive steering inputs, while the 36-spline end accommodates standard aftermarket steering components. At 0.9 lbs and compact dimensions (3.75 x 1.75 x 5.3 inches), this joint installs in tight engine bays without compromising steering feel or responsiveness.

Mechanics and fabricators favor this steering u-joint for installations where OEM shafts won't work—such as engine swaps, frame modifications, or dropped axle builds. The single-joint configuration works best when shaft angles remain under 15 degrees; for sharper angles or length constraints, consider stacking multiple joints strategically through the steering column. Proper installation with quality u-joint bolts and periodic greasing (if applicable to your joint type) ensures years of trouble-free operation and maintains the precise steering feedback essential for safe vehicle control.
