Product Description

The aFe 46-71060B Pro Series Rear Differential Cover is engineered for heavy-duty GM trucks and chassis cabs from 2001 to 2019 equipped with AAM 11.5 rear axles. Crafted from rugged cast aluminum and reinforced with ribs, this cover adds strength while internal and external fins expertly dissipate heat - improving axle fluid longevity and performance. The wrinkle-black finish and machined fins give it a custom look under the vehicle. :contentReference[oaicite:1]{index=1}

Installation is bolt-on using the factory 14-bolt pattern, with no drilling or modifications required. Pre-calibrated sight-glass ensures correct fluid fill, and dual magnetic plugs trap wear particles. The design increases fluid capacity by approximately 1 quart for enhanced thermal stability during towing or heavy-duty use. Every kit includes all necessary hardware for a hassle-free install. :contentReference[oaicite:2]{index=2}

Ideal for owners upgrading axle durability and cooling - whether towing, hauling, or performance-building - this cover brings both functional and stylistic benefits without emissions restrictions. :contentReference[oaicite:3]{index=3}
