Description
aFe POWER Front & Rear Differential GUARD Package w/ PROGUARD Gear Oil – RAM 2500 & 3500 6.7L Cummins
The aFe POWER Front & Rear Diff GUARD Package delivers complete, heavy-duty protection for your drivetrain while simplifying maintenance with a fully integrated service kit. Engineered specifically for 4x4 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins, this package includes front and rear differential covers, all required installation hardware, and 8 quarts of PROGUARD Synthetic 75W-90 gear oil—everything needed for a full front and rear axle service.
Manufactured from durable cast aluminum with reinforced ribs, these Pro Series differential covers provide superior strength and rigidity over factory covers while improving thermal efficiency. The black powder coat finish with machined cooling fins enhances corrosion resistance and promotes efficient heat dissipation during towing, off-road use, and heavy-duty operation.
Each cover features neodymium magnetic drain and fill plugs to capture harmful metal particles, protecting gears and bearings from premature wear. A large oil level sight glass allows for quick visual inspection, while the calibration plug set to factory oil levels eliminates the risk of overfilling. Increased oil capacity over stock further improves lubrication and cooling performance over extended drive cycles.
This kit includes a Front AAM 9.25”-12 bolt cover and a Rear AAM 11.5”/12.0”-14 bolt cover, making it a precise fit for late-model Cummins-powered RAM trucks. The included PROGUARD Synthetic 75W-90 gear oil exceeds API GL-5 specifications and is fully compatible with both open and limited-slip differentials.
