Premium Differential Cover Designed for 11.5" or 12" 14-Bolt AAM Rear Axle

If you're serious about keeping your rear differential cool under load, the Banks Black Ops Ram-Air Differential Cover Kit delivers real engineering where it matters most. Designed specifically for 2019–2024 Ram 2500/3500 and 2020–2025 GM 2500/3500HD trucks, this cover doesn’t just look the part—it’s a patented, purpose-built system that actively manages heat and fluid flow better than anything else on the market. Whether you're towing heavy, hauling up long grades, or just want to extend the life of your drivetrain, this is one upgrade that pulls its weight. At the heart of this system are Ram-Air scoops—a unique design feature that forces cool, high-velocity air through the cover’s external fins. This breaks through the dead air zone found behind most rear differentials and results in up to 118% better cooling than flat-back covers in controlled testing. On the inside, the cover uses radiused fluid guides and internal heat fins to channel oil exactly where it needs to go—over bearings, gears, and the pinion—without stirring up excess heat or causing aeration.

High-Quality Aluminum Construction with Bolt-On Design

Despite its aggressive cooling capabilities, this cover doesn’t sacrifice practicality. The die-cast A380 aluminum body is strong and precise, with a dry-mount Viton O-ring seal that eliminates the need for messy RTV during install. You’ll also find a recessed magnetic drain plug, angled fill port, and a sight glass with contrast screen, making fluid checks and changes quick and clean without pulling the cover off. Fitment is spot-on, too. It clears factory components like the spare tire heat shield and Panhard bars while maintaining factory ground clearance. It even fits OEM locker-style differentials and supports aftermarket upgrades like sway bars or air suspension with the proper spacers. Whether you’re building a tow rig or just want to get the most out of your truck’s rear axle, this cover was designed to work smarter, not just harder.
