For fabricators and suspension system builders. RockJock'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, features a .5625" thru bolt hole, and a 1.600" mounting width. The outer shell is .180" DOM tubing, and is fitted with a zerk fitting for external greasing. Retaining washers are heat-treated steel.
