Steering Coupler OEM Rag Joint

The Borgeson Steering Coupler OEM Rag Joint (model 053143) is a precision steering intermediate shaft component designed for vehicles requiring reliable connection between the steering box and column. This universal rag joint serves as the flexible coupling point in classic, hot rod, and custom vehicle steering systems, accommodating misalignment while transmitting steering input from driver to wheels. Whether you're restoring a vintage cruiser or engineering a custom build, this steering coupler eliminates binding and vibration that rigid couplers introduce.

Manufactured from steel in natural finish, the steering rag joint features a 3/4-inch 30-spline input shaft mating with a 1-inch 48-spline output shaft, providing dual spline configurations for broad compatibility across steering box and column interfaces. The rubber or composite flexing element inside the rag joint absorbs road shocks, steering gear backlash, and minor angular misalignment—critical for protecting steering linkage and reducing feedback harshness. Weighing just 1.44 pounds, this OEM-style coupler maintains factory-correct dimensions (6.7 x 4.35 x 3.9 inches) while delivering the durability required for both street and performance applications.

Mechanics and enthusiasts favor Borgeson steering couplers for restoration work, street rod assembly, and custom suspension builds where OEM-style steering geometry must be preserved or adapted. The mixed spline configuration allows coupling dissimilar steering box and column sizes without custom machining. Installation is straightforward: bolt the coupler between steering components, ensuring splines are fully seated and fasteners are torqued to specification. For vehicles with worn factory couplers, binding steering, or non-stock steering component combinations, this universal rag joint provides the flexible, reliable connection that keeps steering response smooth and predictable on every drive.
