For fabricators and suspension system builders. Currie's Johnny Joints® offer 30 degrees of unrestricted movement in any direction as compared to 22 degrees on a common heim joint. The bushings in the Johnny Joint® rod ends are made with a high-density, "tough 88" urethane that encases the inner ball. It is a very durable material, and is impervious to weather. The special center ball is heat-treated steel for extra strength, cross-drilled for thru-bolt lubrication, features a 9/16" thru bolt hole, and a 2 5/8" mounting width. The outer shell is .180" DOM tubing, and the retaining washers are heat-treated steel. 9/16" greasable bolt with nut and washers included.
