PPE Cast Aluminum Rear Differential Cover
Protect your rear differential and improve thermal performance with the PPE Cast Aluminum Rear Differential Cover. Constructed from premium A356.0-T6 heat-treated aluminum alloy, this heavy-duty cover increases fluid capacity, enhances cooling efficiency, and strengthens the differential housing for demanding towing, hauling, and performance applications.
Key Features
- Manufactured from premium A356.0-T6 heat-treated cast aluminum alloy
- Precision-cast using permanent steel molds for exceptional strength and dimensional accuracy
- Increases differential fluid capacity by 0.57 quart
- Half-inch external cooling fins improve heat dissipation and impact resistance
- Internal windage scrapers reduce fluid aeration, heat generation, and parasitic power loss
- Cross-bracing design formed by external fins and internal scrapers increases housing rigidity
- Cast-in gussets provide additional flange support and structural strength
- 304 stainless steel fill and drain plugs with high-temperature neodymium magnets
- Viton O-rings provide reliable leak-free sealing
- Factory-level fill plug placement ensures proper fluid servicing
Benefits
By increasing fluid capacity and improving cooling efficiency, this differential cover helps maintain proper lubrication and reduce operating temperatures. Internal windage scrapers promote more efficient power transfer by minimizing fluid churning, while integrated magnetic service plugs capture harmful metal particles to help extend differential life and performance.
Fitment
Designed for rear axles equipped with build code SU8. Not compatible with AAM 9.5" rear axles equipped with build code SU7.
What's Included
- PPE cast aluminum rear differential cover
- Magnetic fill plug with Viton O-ring
