aFe Pro Series Front & Rear Diff Guard Package

2019–2025 RAM 2500/3500 6.7L Cummins

Part #: 46-7702AB

Overview

The aFe Pro Series Front & Rear Differential Guard Package is engineered to provide superior protection and enhanced performance for the drivetrain of your RAM 2500 or 3500 equipped with the 6.7L Cummins engine from 2019 through 2025. Designed for truck owners who demand durability and reliability under heavy-duty conditions, this comprehensive kit safeguards your front and rear differentials against impacts and wear while improving thermal management. It is an ideal upgrade for off-road enthusiasts, work trucks, and anyone looking to extend the life and efficiency of their vehicle’s drivetrain components.

This package includes everything needed for a complete differential service, combining robust construction with premium synthetic gear oil to ensure optimal lubrication and cooling. With increased oil capacity and advanced cooling features, the aFe Pro Series diff guards help maintain lower operating temperatures and reduce the risk of gear wear during demanding use.

Key Features

Designed to deliver both protection and performance, the aFe Pro Series differential covers incorporate several advanced features:

• Durable cast aluminum construction with reinforced ribs for superior strength and impact resistance
• Increased oil capacity compared to factory covers, allowing for improved lubrication and extended service intervals
• Integrated internal and external cooling fins that dissipate heat efficiently to maintain optimal operating temperatures
• Magnetic drain plugs and deep reach fill plugs that capture metal particles and contaminants for enhanced drivetrain protection
• Calibration plug sets to the factory oil level to prevent overfilling and ensure proper fluid volume
• Oil level sight glasses for quick and easy visual inspection without removing the cover
• Comes complete with 8 quarts of 75W-90 premium PROGUARD Synthetic gear oil, exceeding API GL-5 standards for both open and limited slip differentials
• All necessary installation hardware included for a straightforward upgrade

Construction & Design

The differential covers are precision cast from high-quality aluminum, chosen for its excellent strength-to-weight ratio and superior heat dissipation properties. Reinforced ribs are strategically integrated into the design to enhance structural rigidity and protect against impacts from rocks, debris, and rough terrain. The cooling fins on both the interior and exterior surfaces maximize heat transfer from the gear oil to the surrounding air, helping to prevent overheating during heavy towing, hauling, or off-road driving.

Each cover features a magnetic drain plug that attracts and holds metal shavings, reducing wear on internal components and extending the life of your differential. The deep reach fill plugs simplify fluid changes and maintenance, while the calibrated plugs ensure the oil level matches factory specifications for optimal performance.

Installation & Fitment

This Pro Series differential guard package is designed for direct fitment on 2019 to 2025 RAM 2500 and 3500 models equipped with the 6.7L Cummins engine. Installation is straightforward and requires no vehicle modifications. The kit includes all necessary hardware and detailed instructions, allowing for a hassle-free upgrade that can be completed with basic hand tools. The included premium synthetic gear oil facilitates a full differential service during installation, making this a convenient all-in-one solution.
