Show original supplier description
Crafted from A356-T6 heat-treated aluminum, it provides strength without excessive weight and boasts massive internal and external cooling fins for superior heat dissipation. This design helps maintain stable fluid temperatures, which is crucial during demanding use like long hauls, heavy towing, or off-road excursions, thereby extending the life of your front differential components. This differential cover increases the fluid capacity by an additional 3/4 quart over the stock unit, providing a greater thermal reserve for extended operation in hot conditions. Additionally, a 1/8-inch NPT port is integrated for the convenient installation of a temperature sensor, allowing for real-time fluid temperature monitoring. The package also includes zinc-plated stainless steel hardware for a clean, corrosion-resistant assembly. Furthermore, cast-in gussets and an internal windage scraper contribute to improved housing strength, rigidity, and reduced heat generation from fluid churning, forming an ultra-strong cross-bracing structure. This differential cover is compatible with 2011-2025 GM Silverado and Sierra 2500HD/3500HD models. It is backed by a limited lifetime warranty, reflecting its robust construction and PPE's confidence in its performance.
