The new Roto-Joint axle housing bushing completes the package and ensures bind-free articulation. This 8 Roto-Joint package is the ultimate combination of street comfort and race winning capability. For Pro-Tour cars that see highway use, this kit is like having rod end suspension that just happens to be comfortable.

Spanner Wrench-

The Spanner wrench is used for adjusting and disassembling UMI Roto-Joints. Over time the Delrin race inside the Roto-Joint may wear, the spanner wrench is used to tighten the adjusting ring applying more pressure to the delrin inside. The spanner wrench is also used to disassemble the Roto-Joint for cleaning, inspection and rebuilding.
