Description
Heavy‑Duty Construction for Serious Loads. This ATS Diesel Performance Protector AAM 11.50-Inch Differential Cover is cast from high-strength aluminum and finished with a durable black powder coat, making it a robust upgrade for demanding applications. Designed to replace the factory cover on the AAM 11.5″ rear axle, it resists warping, cracking, and fatigue under high torque loads, heavy towing, and off-road abuse. The rigid construction helps maintain seal integrity and gear protection in extreme conditions, giving you confidence in your drivetrain’s durability.
Increased Oil Capacity & Enhanced Cooling. By adding approximately 2.5 quarts of oil capacity over the stock differential cover, this ATS Diesel Performance Protector AAM 11.50-Inch Differential Cover improves gear lubrication and helps regulate operating temperatures. Integrated cooling fins further enhance thermal dissipation, keeping the differential cooler and more stable under load. Whether you're towing long distances or navigating tough terrain, the added fluid volume and cooling design contribute to smoother operation and reduced wear.
Improved Serviceability & Maintenance Features. The ATS Diesel Performance Protector AAM 11.50-Inch Differential Cover includes a built-in magnetic drain plug that simplifies fluid changes and helps capture metal particles from gear wear. Its bolt-on, direct-fit design ensures easy installation without the need for modifications. The combination of increased fluid capacity, corrosion-resistant finish, and service-friendly features means longer intervals between maintenance and a cleaner, more efficient servicing process.
Installation. Putting this ATS Diesel Performance Protector AAM 11.50-Inch Differential Cover on your RAM 2500 takes 2 hours to install.
Warranty. There is a limited lifetime warranty on this product.
