Double U-Joint 3/4in DD x 3/4in DD

The Borgeson Double U-Joint 3/4in DD x 3/4in DD is a precision-engineered driveshaft coupling designed for street rods, classic cars, and custom vehicle builds where smooth power delivery is critical. This component serves as the articulated link between your steering column and driveshaft, allowing controlled flex while maintaining a solid mechanical connection.

This Borgeson unit features dual 3/4-inch double-D bore (DD) connections on both ends, meaning each shaft coupling point accepts 3/4-inch double-D shafts with precision fit and minimal runout. The double-D profile provides superior torque transfer compared to round bores and eliminates the slip common in older single-u-joint designs. The compact design and lightweight construction make it ideal for tight engine bays.

This coupling is perfect for fabricators, hot-rodders, and mechanics upgrading steering or driveline systems on custom vehicles, vintage restorations, or off-road buggies. Its reliable operation ensures driver comfort over extended drives, making it an essential component for any custom build.
