Now those of you with GM 1500 trucks have 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 to lubricate with. Cool, dense fluid lubricates better, which will extend differential service life. The internal heat sinks are 1/2 of an inch tall and the external fins measure nearly 5/8 of an inch.

Made in the USA from high-quality cast aluminum for strength and optimum heat dissipation, PPE’s differential covers offer industry-leading fluid cooling.

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

This cover also features a pre-tapped 1/8 inch NPT port for a temperature probe, capped off with a stainless steel plug.
