Description
Cast Aluminum Rear Differential Cover Excessive heat can degrade the protective qualities of differential fluid, leading to accelerated wear of gears and bearings. In limited-slip differentials, constant high temperatures can break down clutch packs and friction modifiers, resulting in reduced efficiency and compromised traction control. Cast from high-grade A356.0-T6 aluminum alloy, the PPE differential cover adds .7 quart of fluid capacity and features half-inch external cooling fins for long-lasting heat management and performance.
