When the internal seals and springs wear, the governor may short-cycle the compressor, causing excess moisture in the tanks or pressure loss. This kit restores reliable 105 PSI cut-in and proper cut-out thresholds, preventing moisture buildup and maintaining consistent braking performance. It includes a dust cap and fits most heavy-duty trucks and buses that use a Wabco-style compressor governor with 1/8-27 NPTF ports.
