Forged Johnny Joint® rod ends feature forged steel construction, a 1"-14 left hand threaded shank and come fully assembled with our standard Johnny Joint® internals (2.585" wide ball center with a .640" thru bolt hole). These units are externally greasable via a zerk fitting. Finished in gold zinc plating. We also keep the jam nuts for these units on hand at all times as well. These can be used in any Currie adjustable lower control arm, as well as in any type of universal application for those building their own arms.
