Banks Power Black Differential Cover Kit 12in AAM - 19286

• Patented design cools 5X better than flat-backs

The Banks Power Black Differential Cover Kit 12in AAM (PN 19286) is a patented Ram-Air® differential cover engineered to keep rear axle fluid cooler on trucks running the 11.5" or 12" 14-bolt AAM rear axle. Built for 2019-2026 RAM trucks and 2020-2026 Chevrolet/GMC trucks, this cover replaces the stock flat-back cover with a forced-air cooling design that Banks backs with real-world towing and sustained-load testing. If you tow, haul, or just want longer fluid life and easier differential maintenance, this is a grounded upgrade worth understanding before you buy.

Key Features & Benefits

• Patented Forced-Air Cooling Design - Ram-Air scoops force air through heat radiation fins, and Banks' FlowThru Fins® move that heat through the cover and out to the passing airstream, directly addressing the dead-air zone that forms behind a stock differential cover.
• Tested Cooling Performance - In on-road towing tests, Banks reports this cover cools 5X better than high-capacity flat-back aftermarket covers, and 118% better than competitors in sustained 200 hp, 60 mph testing - meaning cooler gear oil under real load, not just on paper.
• Fluid Dynamics Engineering - An internal ring gear raceway guides fluid directly to the ring-and-pinion interface and out to the axle tubes and bearings, while the design reduces fluid aeration so your gear oil keeps its lubricating properties longer.
• Easier Ongoing Maintenance - A sight glass lets you check fluid level without removing the cover, an angled fill port simplifies topping off, and a magnetic drain plug catches metal fines during service - all while retaining your stock fluid capacity.
• Built to Survive the Trail and the Highway - The Ram-Air scoops are designed to break away if struck, protecting the cover from impact damage, while the cover maintains stock ground clearance so you're not sacrificing clearance for cooling.
• Clean, Reliable Sealing - An O-ring seal replaces messy RTV sealant, making future service cleaner and more consistent, and a dedicated temp sensor port is included for those running differential temperature monitoring.

Fitment

This Ram-Air differential cover kit is built for 2019-2026 RAM trucks and 2020-2026 Chevrolet/GMC trucks equipped with the 11.5" or 12" 14-bolt AAM rear axle - the fitment is axle-specific rather than purely year/make/model, so confirm your truck's rear axle type before ordering. Banks notes specific applicability to 2019+ RAM 6.4L gas trucks. Because 14-bolt AAM axles are most commonly found on heavy-duty RAM 2500/3500 and Chevrolet/GMC 2500HD/3500HD platforms, double-check your axle code or consult your owner's documentation if you're unsure whether your specific truck uses this axle before purchasing.

Frequently Asked Questions

It fits RAM trucks equipped with the 11.5" or 12" 14-bolt AAM rear axle, with Banks specifically noting applicability to 2019+ RAM 6.4L gas trucks - fitment depends on axle type, not just year/trim, so confirm your rear axle before ordering.

Will this cover hold my stock amount of gear oil?
Yes, Banks designed this cover to retain stock fluid quantity while improving cooling and fluid routing internally.

Can I monitor differential temperature with this cover?
Yes, it includes a dedicated temperature sensor port for use with a differential temp gauge or monitoring system.
