Installation Instructions

PPE Differential Covers 238051020 Details

Made from high-quality cast A356.0-T6 aluminum for strength and optimum heat dissipation. PPE’s differential covers offer industry-leading fluid cooling. Equipped with internal heat sinks and external cooling fins, increasing the pan’s surface area helping dissipate heat. This makes for a much cooler and denser oil. Cool, dense fluid lubricates better, which will extend differential service life.

To keep the fluid clean, PPE installed its exclusive high-powered Neodymium magnet-equipped fill plug pulls harmful ferrous metal particles right out of the oil before they have a chance to attack the bearings and gears.

Key Features

  • Increased oil capacity
  • Cast from high-grade aluminum alloy
  • Significant reduction in differential fluid temps
  • Adds additional strength to gear housing
  • Billet 304 stainless steel Neodymium magnet equipped fill plug
  • Limited lifetime warranty


NOTE: This product will only fit on 2013 and newer Dodge Cummins trucks configured with a rear leaf spring suspension. Because of clearance issues, this differential cover will not fit on trucks configured with a rear coil spring.
