A Complete Drivetrain Upgrade In One Box

Towing and hauling put real stress on both ends of your 2019-2025 Ram 2500 or 3500 drivetrain, and upgrading just one differential cover only solves half the problem. The aFe Power Front & Rear Diff Guard Package takes care of both at once, pairing a front AAM 9.25 inch 12-bolt cover with a rear AAM 11.5/12.0 inch 14-bolt cover in a single complete kit. Both covers are cast from durable aluminum and finished in black powder coat with machined fins, giving you real heat dissipation at both axles rather than leaving the front exposed to factory limitations. Each cover increases oil capacity over stock and uses neodymium magnetic drain and fill plugs to capture metal particles before they cause additional wear. aFe doesn't stop at just the covers either, this package includes 8 quarts of PROGUARD Synthetic 75W-90 gear oil, enough to fully service both the front and rear axles in one straightforward job. With everything from hardware to fluid included, this is a genuinely complete package for anyone who wants to upgrade their entire drivetrain's protection and cooling in a single install.

Matched Front And Rear Covers Backed By Premium Gear Oil

The aFe Power 46-7702AB Front & Rear Diff Guard Package is engineered specifically for 2019-2025 Ram 2500 and 3500 4x4 trucks equipped with a front AAM 9.25 inch 12-bolt axle and a rear AAM 11.5 or 12.0 inch 14-bolt axle. Both the front and rear covers are constructed from durable cast aluminum with reinforced ribs, built-in internal and external fins, and a black powder coat finish for corrosion resistance and improved heat transfer under demanding conditions. Each cover features a calibration plug set to the factory oil level to help prevent overfilling, along with an oil level sight glass for quick visual inspection without removing any plugs. Neodymium magnetic drain and deep reach fill plugs are used throughout the system to capture loose metal particles for added gear protection. The kit includes 8 quarts of PROGUARD Synthetic 75W-90 gear oil, which exceeds API GL-5 performance requirements and is suitable for both open and limited slip differential applications. All necessary mounting hardware is included for a complete, ready-to-install package. This product does not require a CARB EO number.
