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 ball is heat-treated steel for extra strength. The 3" joint is lubricated via a zerk fitting on the outer shell -- an outer shell constructed of tough 4130 chromoly. The retaining washers are machined out of 4340 chromoly and feature a snap ring safety machined into their face to protect the snap ring from coming out. The center ball is heat-treated chromoly steel for extra strength and features a 3/4" thru bolt hole and a 3 1/4" mounting width.
