AEV Rear Differential Cover | AT4, AT4X, Denali | Chevrolet Colorado / GMC Canyon (2023-2026) | P/N 18060031AA

Factory differential covers are designed to meet cost and baseline durability targets, offering limited impact resistance and can be difficult to service. The AEV Rear Differential Cover is engineered to improve both durability and serviceability without compromising factory performance The AEV Differential Cover is manufactured from high-strength nodular iron, providing a substantial increase in strength over the OE stamped steel cover. The housing is designed to resist deformation under impact, particularly along the lower edge where contact is most likely to occur Recessed mounting hardware further reduces the risk of bolt damage in off-road conditions, helping maintain sealing integrity and long-term reliability
