The QC Pinion Seal 3/4 by ALLSTAR PERFORMANCE is an essential component designed to prevent gear oil leakage at the pinion shaft entrance of 3/4-inch differential housings. This seal is crucial for maintaining the integrity of the differential, especially during rebuilds or upgrades, ensuring that oil loss and potential damage are minimized.
Featuring a precision-engineered elastomer lip, the seal effectively rides against the pinion shaft while accommodating rotational speeds without generating excessive friction. Its robust design is built to withstand thermal cycling from -20°F to +220°F, making it suitable for a variety of operating conditions. The lightweight construction (0.16 lbs) reflects efficient engineering, allowing for straightforward installation.
Ideal for hot rodders, truck enthusiasts, and transmission shops, the QC Pinion Seal 3/4 is used during differential rebuilds and when converting to locking differentials. Symptoms of a failing pinion seal include visible oil weeping around the driveshaft, making timely replacement essential for vehicle maintenance.
