These heavy duty steel rod ends have a red polyurethane insert that eliminates metal to metal contact, cushions shock and is quieter than a standard heim joint.
This rod end is designed for radial loads only, it does not articulate to compensate for mis-alignment as a sperical bearing rod end would.
Recommended uses would include ladder bars or panhard bars on street driven vehicles.
NOT intended for use in 3-link, 4-link, steering or any other applications which put a twist, axial or side load on the joint.
The 5/8" version has sleeves to use either a 5/8" or 1/2" bolt while the 3/4" accepts a 5/8" bolt only.
