Some later H-D models come with a TPMS (Tire Pressure Monitoring System) built into the wheels. This TPMS bracket fits the existing valve stem inside custom Performance Machine wheels. It allows a bolt-on installation of the OEM 42300118 (repl. by 42300142) / 42300119 TPMS sensor to retain full TPMS functionality. Complete with bracket, O-ring, hardware and installation instructions. Note: Does not include the TPMS sensor.
