Selecting high-quality sensors, service packs, and accessories for today's vehicles ensures that quality standards are met and customers can drive safely with their TPMS system fully operational. Schrader service packs provide the essential components that must be replaced each and every time a TPMS-equipped vehicle requires a tire to be removed for service. Components include (but are not limited to) a Schrader valve core, sealing cap, grommet and nut. In some instances a stem is provided as part of the serivce pack. This particular service pack (part #20043) is applicated for fitment to specific Chrysler and Dodge vehicles equipped with rubber valve TPMS sensors. For complete application coverage, reference your Schrader application guide or visit the Schrader International website.
