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, cross-drilled for thru-bolt lubrication, features a .572" thru bolt hole, a 3.150" mounting width and one flange is cut off for use on the frame end of front trac bar applications. The outer shell is .180" DOM tubing, and the retaining washers are heat-treated steel.
