Autopart International 1776-520355 Differential Pinion Seal

The Autopart International 1776-520355 is a precision-engineered pinion seal designed to prevent fluid leaks in differential and driveline assemblies. This critical component creates a tight seal around the pinion shaft where it exits the differential housing, maintaining proper lubricant levels and protecting internal components from contamination.

Key Features:

• Designed to meet or exceed OEM specifications for reliable sealing performance
• Manufactured with application-specific elastomer materials for optimal durability
• Precision-molded construction ensures proper fit and ease of installation
• Helps prevent differential fluid leaks and contamination
• Essential replacement component for differential maintenance and repair

Pinion seals are wear items that should be replaced during differential service, pinion bearing replacement, or whenever leaks are detected. Proper installation with the correct seal is critical for maintaining differential performance and preventing costly damage from fluid loss.
