    These Pro-1 rod ends are general purpose, 2-piece, heavy duty rod ends. They feature a chromoly steel body and are black oxide coated to resist corrosion. Heat treated, precision ground ball without a race (metal to metal contact). Pro-1 ends will withstand a greater static load than our "Standard" or "Precision" rod ends.

    Applications: Steering & suspension components on moderate to high horsepower applications.

    Assembly Tip: To ease assembly, be sure to run a tap or die through the threads on chrome plated fasteners and apply an anti-seize compound to prevent galling of the threads.
