2-Piece General Purpose Rod Ends

CM
SKU# FKCM8

These are economy style rod ends and are metal-to-metal, meaning the ball rides on a formed portion of the steel body. Metal-to-metal allows for a fairly high misalignment capability with good strength / cost. Popular in linkage applications

3-Piece General Purpose Rod Ends

Jm
SKU# FKJM8

These are general purpose rod ends featuring a heated treated race for the ball to ride on. The "race" component is located between the housing and the ball. The advantage is a closer fit and a higher degree of precision is achieved between the ball and race. The 3-piece rod end also has a larger bearing surface giving it better wear over time. 3-piece style rod ends have less misalignment capability than 2-piece CM / CF series rod ends but are similar in strength.
