Product details
This Bushing end is designed to replace ¾”-16 right hand threaded rod ends by simply removing the rod end and screwing in this Roto-Joint assembly. This item works excellent to replace worn out rod ends or rod ends making unbearable noise. The Roto-Joint is an easy replacement and is supplied fully assembled with grease fitting, new jam nut and a clear zinc finish. Bushing width is 2.600” with 3/4”-16 right hand threads, 2.000” of thread adjustment and accepts a 14mm bolt. Our replacement bushing end features threads CNC machined from 4140 Chrome Moly steel, DOM tubing and TIG welded for superior strength and thread durability. Spanner Wrench- This spanner wrench is used for adjusting and disassembling Roto-Joints used in all UMI Performance products. Over time if the delrin race inside the Roto-Joint would 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. This fabricated Roto-Joint is designed to replace spherical rod ends on UMI Performance control arms for the 1978-1996 GM B-Body. This item will also work on many other brand control arms for the above listed vehicles that utilize a ¾”-16 right hand threaded rod end. See part # 0020L for left hand threaded Roto Joint. 90020 - Control Arm Roto-Joint End, ¾”-16 Right Hand Thread- GM B-Body
