PPE Heavy Duty Rear Differential Cover with Brushed Finish for 2001-2019 Chevy/GMC 6.6L Duramax LB7, LLY, LBZ, LMM, LML, L5P.
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.
