PPE 138051000 Heavy Duty Differential Cover - Raw

Upgrade the rear differential on your GM Silverado/Sierra 2500HD/3500HD or Dodge Ram 2500/3500 with the PPE 138051000 Heavy Duty Differential Cover - Raw. 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 .63 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.

Only works with vehicles equipped with AAM 14-11.5'' axle. For Gas trucks please confirm if you have an 11.5" differential before ordering.

Ram Note: 

This product will only fit on 2013+ Ram diesel models with a rear leaf spring suspension. Due to clearance issues, this cover will NOT fit on rear coil spring applications.
