ACDelco 87845955 Differential Drive Pinion Gear Seal

The ACDelco 87845955 is a premium differential drive pinion gear seal designed to prevent lubricant leakage from the differential housing where the pinion shaft exits. This critical seal maintains proper fluid levels within the differential assembly, protecting gears and bearings from premature wear and contamination.

Key Features:

• Precision-engineered seal designed for exact fit and reliable performance
• High-quality materials resist heat, chemicals, and degradation from differential fluid
• Prevents gear oil leakage at the pinion shaft interface
• Helps maintain optimal differential lubrication and component longevity
• Direct replacement for worn or leaking original equipment seals

ACDelco differential seals are manufactured to meet strict OE specifications for durability and sealing performance. Regular inspection and replacement of pinion seals is essential maintenance to prevent costly differential damage from fluid loss.
