Part #: 90011L
This fabricated Roto-Joint is designed to replace spherical rod ends on UMI Performance control arms for the 1964-1972 GM A-Body, 1978-1988 GM G-Body and the 1982-2002 Camaro/Firebird. This item will also work on many other brand control arms for the above listed vehicles that utilize a "-16 left hand threaded rod end. See part # 0011 for right hand threaded Roto Joint. This Bushing end is designed to replace "-16 left 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 2.400" with 3/4"-16 left hand threads, 2.000" of thread adjustment and accepts both " and 12mm bolts. Our replacement bushing end features threads CNC machined from 4140 Chrome Moly steel, DOM tubing and TIG welded for superior strength and thread durability.
