Steering U-Joint 9/16in-26 x 3/4in Smooth

The Borgeson Steering U-Joint 9/16in-26 x 3/4in Smooth is a universal joint coupling engineered to connect steering shafts with misaligned or angled connections in automotive steering systems. This single-joint design accommodates both 9/16-inch 26-spline and 3/4-inch smooth shaft interfaces, making it a versatile component for custom steering installations, vehicle restorations, and performance builds where factory steering geometry requires modification or extension.

Built from steel in natural finish, this u-joint combines durability with straightforward installation. The 9/16-inch 26-spline input accepts shafts commonly found in manual steering boxes and custom steering columns, while the 3/4-inch smooth shaft output connects to intermediate steering shafts or pitman arm assemblies. The smooth bore design eliminates the need for spline matching on the output side, simplifying adapter and shaft selection. At 0.86 lbs and compact dimensions of 3.75 x 1.7 x 5.65 inches, it integrates easily into tight engine compartment layouts.

This coupling is ideal for street rod builders, classic car restorers, and fabricators routing custom steering systems where shaft angles or centerline offsets exist between the steering column and the steering mechanism. The universal design accommodates small angular misalignments typical in modified chassis layouts. Borgeson has established itself as a manufacturer focused on steering component solutions, and this single-joint u-joint reflects that specialization through straightforward, reliable engineering suited to manual and power steering applications alike.

Single u-joints are preferred where space is limited or where only a modest angle correction is needed. Multi-joint designs absorb larger angles but occupy more length. This model's simplicity translates to fewer potential wear points and easier diagnosis if steering feel or vibration develops during operation or testing.
