      Description

      Dependable Leak Prevention for Your Drivetrain. The Motive Gear 8-Inch Rear Differential Pinion Seal is a critical replacement component designed to keep gear oil inside the differential housing of your 1979 Mustang while keeping road contaminants out. A worn seal often leads to unsightly drips and a low oil level, which can cause excessive heat and premature gear wear. By installing the Motive Gear 8-Inch Rear Differential Pinion Seal, you provide a tight, professional-grade barrier that ensures your 8-inch rear end remains properly lubricated and free from the messy residue associated with old, brittle seals.

      Advanced Elastomer Construction for Maximum Durability. The Motive Gear 8-Inch Rear Differential Pinion Seal is manufactured using high-quality elastomer materials that are specifically formulated to resist the harsh chemicals and additives found in modern gear lubricants. This robust material maintains its flexibility across a wide range of temperatures, preventing the seal from cracking in extreme cold or hardening under the intense heat generated during long drives. Choosing the Motive Gear 8-Inch Rear Differential Pinion Seal means investing in a part that is built to endure the high rotational speeds of your pinion shaft without losing its sealing integrity over time.

      Installation. Putting this Motive Gear 8-Inch Rear Differential Pinion Seal on your Mustang takes 3 hours to install.

      Warranty. There is a 1-year or 50,000-mile warranty on this product.

      Application. The Motive Gear 8-Inch Rear Differential Pinion Seal fits 1979 Mustang models.
