Overview
The G2 Chrysler 8.25 Inch Aluminum Cover, part number 40-2029AL, is a raw cast aluminum rear differential cover for Chrysler 8.25 inch rear axles. It guards the ring and pinion and is built to pull heat away from the gear oil, which G2 links to longer bearing life.
The casting is heat treated and shot peened so it can absorb a direct impact, and the cover keeps a natural aluminum look rather than a painted finish. Chrysler and Jeep are named as popular axle manufacturers, though no years or models are given.
Key features
- Cast from lightweight aluminum to dissipate heat
- Reinforcing ribs add rigidity to the cover
- Heat treated and shot peened for impact handling
- Seal face machined to help prevent leaks at fit-up
- Natural raw aluminum finish
Choosing the right cover
The rear differential cover is one of the simplest parts to overlook, yet it protects the ring and pinion from road grit and water. On a rear axle that sees mud, sand or deep water, a sound cover and a clean seal keep the gear oil where it belongs. Many owners pull the cover to inspect the gears when they change fluid, and that is a good time to check the magnet and clean out any fine metal particles.
When choosing a cover, match the axle size first, then look at the sealing surface and how the bolts seat. A raw aluminum finish shows wear and scratches more readily than paint, so a light coat of protectant can be used on the outside. If a new cover is fitted, a fresh gasket and gear oil are usually replaced at the same time, and the axle breather should be checked for blockage.
