The RAC Link Hardware Upgrade Kit is designed to replace the old screw and post base system found in both Gen 1 and Gen 2 RAC Links, eliminating the need for Loctite. This upgrade allows the ear-cup to freely rotate without worry of the screw post backing out. Ideal for those who have previously purchased the screw and post base RAC Link system and wish to upgrade.

The kit does not include the springs. If you need replacement springs, please click here: RAC Link Replacement Springs
