Description
Aeroflow Ford 9″ Differential Viton Pinion Seal
Engineered for extreme thermal stability and superior fluid retention in high-performance Ford 9-inch rear axle assemblies.
Product Overview
The Aeroflow Performance AF5075-1008 differential pinion seal is an essential upgrade for high-performance and motorsport applications utilizing a Ford 9-inch rear end. OEM rubber pinion seals deteriorate rapidly at temperatures around 120°C (248°F), leading to severe fluid leakage and catastrophic gear failure under hard acceleration or extended track use. Manufactured from high-grade Viton rubber, this Aeroflow pinion seal resists temperatures in excess of 200°C (392°F) for optimal long-term reliability.
Featuring exact dimensions of 3″ (76.20mm) Outside Diameter, 1.813″ (46.05mm) Inside Diameter, and 0.5″ (12.70mm) overall thickness, the AF5075-1008 delivers a precision press-fit into Ford 9-inch pinion seal retainers and housings.
Key Features
- ☑ Premium Viton rubber formulation withstands heat over 200°C (392°F)
- ☑ Prevents thermal breakdown, hardening, and differential oil leakage
- ☑ Direct fit for Ford 9-inch differential housings and pinion retainers
