Description
A compromised pinion seal is a silent killer for differential performance—once it fails, gear oil leaks onto your brakes and suspension, inviting catastrophic failure on the track or street. The Allstar Performance pinion seal is engineered for the GM 8.5-inch differential, delivering a reliable, OEM-quality seal that prevents costly leakage and keeps your drivetrain protected. This is a bolt-on replacement that takes minutes to install and pays dividends in longevity.
