3/4-30 Rag Joint w/Pinch Bolt

The 3/4-30 Rag Joint with Pinch Bolt from DETROIT SPEED ENGINEERING is a precision steering coupling designed to isolate vibration and misalignment between the steering column and intermediate shaft in high-performance and modified vehicles. This component is essential for builders who have significantly altered frame geometry or installed a custom steering column. It is particularly beneficial for those upgrading to performance suspension systems where stock steering geometry no longer aligns properly.

The rag joint absorbs rotational deflection caused by engine movement, suspension articulation, or chassis flex, preventing binding and extending the lifespan of both steering components and driveline supports. This joint features a 3/4-inch bore diameter and a 30-spline connection with an integral pinch bolt design for secure assembly. The flexible rubber or elastomer insert accommodates angular and parallel misalignment—typically up to 15 degrees—while maintaining consistent torque transmission to the steering gearbox.

This rag joint is ideal for custom-built hot rods and vehicles with modified steering systems. Its pinch bolt clamping mechanism ensures the spline connection remains locked under load, which is critical in vehicles experiencing high cornering G-forces. Detroit Speed Engineering's manufacturing standards guarantee concentricity and durability, making this component suitable for both street-driven performance cars and modified vehicles.
