7/8" RH PTFE Heim Joint with Misalignment Shoulder | FK Rod Ends HRSMX12T | FKBHRSMX12T

FK Rod Ends HRSMX12T – 7/8" Right Hand Thread PTFE Heim Joint with Misalignment Shoulder

The FKBHRSMX12T is a heavy-duty FK HRSMX series 3-piece heim joint featuring a built-in misalignment shoulder for increased angular articulation. The key difference from the HJMX series: the HRSMX has a larger diameter shank than its bore hole — in this case a 7/8" shank with a 3/4" hole — allowing for greater misalignment without sacrificing strength. Pair with the LH version for a fully adjustable link assembly.

HRSMX vs HJMX – What’s the Difference?

The HRSMX series has a larger shank diameter than its bore hole, providing greater misalignment capability. The HJMX series has a matching shank and bore diameter (e.g. HJMX7T = 7/16" shank, 7/16" hole). Choose HRSMX when you need maximum articulation in tight spaces.
