Construction & Design

The rear differential cover is crafted from high-quality cast aluminum, chosen for its excellent strength-to-weight ratio and thermal conductivity. Reinforced ribs add structural integrity to withstand impacts from rocks and debris encountered during off-road driving. The black powdercoated finish not only enhances corrosion resistance but also provides a sleek, aggressive appearance that complements the rugged styling of Jeep vehicles.

Machined cooling fins are strategically incorporated both inside and outside the cover to maximize heat dissipation, helping to maintain lower differential fluid temperatures and prolong component life. The inclusion of a magnetic drain plug ensures that any metal shavings or particles are trapped before they can circulate through the differential, reducing wear and potential damage.
