The aFe Power Pro Series rear differential cover (MPN: 46-71060B) provides superior protection and cooling for heavy-duty GM axles. Constructed from durable cast aluminum with integrated internal and external cooling fins, this cover efficiently dissipates heat from the gear oil to the ambient air. The increased oil capacity helps maintain lower operating temperatures over long-haul or high-load conditions, extending the life of your differential components.

This Pro Series cover is designed for easy maintenance and maximum debris protection. It features a magnetic drain plug and a deep-reach magnetic fill plug to trap metallic particles before they cause wear. A pre-installed oil level sight glass allows for instant fluid checks, while the calibration plug is specifically set to the factory fill level to prevent overfilling.

• Black powder-coated finish with machined cooling fins
• Increased oil capacity over factory housing for improved thermal management
• Magnetic drain and fill plugs capture abrasive ferrous particles
