National Seal GM 8.5 axle seal

The National Seal GM 8.5 axle seal is an OEM-quality replacement seal designed for General Motors 8.5-inch rear differentials. This product is essential for those who have noticed gear oil seeping around the axle shaft or have detected a burning oil smell during aggressive driving. It serves as a critical maintenance item for GM truck and performance vehicle owners.

Engineered to prevent differential fluid loss and contamination, this axle seal maintains pressure integrity under high-stress conditions.

Its compact dimensions allow for a snug fit into the 8.5 differential housing without requiring modification. Keeping this seal in your maintenance kit is a smart choice for anyone running a modified 8.5 rear axle.
