Description

Overview

The G2 Ford 8.8 Inch Aluminum Cover, part number 40-2013AL, is a raw cast aluminum rear differential cover for Ford 8.8 inch rear axles. It protects the ring and pinion and is designed to keep gear oil cooler, which G2 links to longer bearing life.

The cover is made for Ford 8.8 inch and Mazda 8.8 inch axle sizes, so compare the size on your housing to those two before buying.

Key features

  • Cast from lightweight aluminum for heat dissipation
  • Reinforcing ribs for rigidity and strength
  • Heat treated and shot peened for direct hit resistance
  • Machined sealing surface intended to limit leaks
  • Raw natural aluminum finish

Ford and Mazda axle sizes

The Ford 8.8 inch rear axle is a common choice for trail and daily-driven builds, and its cover is often the first part to show wear from rocks and mud. A solid cover protects the ring and pinion while keeping the gear oil contained. Because axle sizes can look alike, measure the housing carefully, including the bolt pattern, before buying.

Cover replacement goes well with fresh gear oil, a new gasket and a check of the axle breather. If the cover has been struck hard, look for cracks around the bolt flange and check the housing face for damage that could cause leaks. A raw aluminum cover can be cleaned with a mild degreaser, and a light coat of protectant on the outside helps keep the surface tidy.
