Construction & Design
The aFe Street Series differential cover is crafted from high-quality die-cast A380 aluminum, chosen for its excellent strength-to-weight ratio and resistance to corrosion. Its rugged design features machined fins that maximize heat transfer from the differential fluid to the surrounding air, effectively reducing operating temperatures. This thermal management is critical for maintaining fluid integrity and preventing premature wear of internal drivetrain components.
The integrated neodymium magnetic drain plug is strategically positioned to attract and hold metal shavings and debris, providing an additional layer of protection by preventing contaminants from circulating within the differential. The cover’s robust construction ensures it can withstand impacts and harsh conditions commonly encountered during off-road driving or heavy-duty use.
