2014-2026 GM 1500 9.5"/9.76"-12 Rear Axle Heavy-Duty Cast Aluminum Rear Differential Cover Brushed (138051210)

Description

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, reducing efficiency and traction control.

Cast from high-grade A356.0-T6 aluminum alloy, the PPE differential cover adds .6 quart of fluid capacity and features half-inch external cooling fins for long-lasting heat management and performance.

Built-in windage scrapers inside the PPE cover ensure precise fluid distribution around the gears, lowering heat buildup and minimizing parasitic loss. Together with the vertical external fins, they form a strong cross-bracing structure that improves load distribution and enhances impact resistance.

The fill plug is positioned at the factory level. Both the fill and drain plugs feature a high-temperature-rated neodymium magnet that captures ferrous particles for added protection.
