2001-2019 GM, 2001-2018 RAM AAM 11.5 in -14-Bolt Heavy-Duty Cast Aluminum Rear Differential Cover - Brushed - Pacific Performance Engineering - 138051010

Heavy-Duty Aluminum Rear Differential Cover for 2001-2019 GM/RAM 2500 11.5"-14

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 .75 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. By reducing excessive fluid churning, these scrapers lower heat buildup and minimize parasitic loss, promoting more efficient power transfer. 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 precisely positioned at the factory level. Both the fill and drain plugs feature a powerful, high-temperature-rated neodymium magnet that captures ferrous particles for added protection.

Note1: Only works with vehicles equipped with AAM 11.5”-14 axles.Note2: Not compatible with RAM 2500/3500 with coil-spring rear suspension. See 2001-2019 GM, 2001-2018 RAM AAM 11.5"-14-Bolt Heavy-Duty Cast Aluminum Rear Differential Cover, p/n 238051000 for those applications.
