Product Description

Banks' Ram-Air differential cover is engineered for AAM 11.5"/12" rear axles used on 2019-2026 Ram 2500/3500 and 2020-2026 Chevy Silverado & GMC Sierra 2500HD/3500HD. Patented external scoops drive cool air through the fin channels while internal fluid guides deliver oil precisely to the ring gear and bearings. The result is faster heat rejection and more consistent lubrication under tow, grade, and off-road loads.

The A380 die-cast housing retains OE ground clearance and adds service-friendly touches: a 20° fill port, magnetic drain, sight glass, and a 1/8" NPT sensor port. It bolts on to the factory 14-bolt pattern and is compatible with OEM locker differentials. For Ram trucks with an OEM rear sway bar, a spacer kit is required; airbag-only rear suspensions are excluded. Built for durability and thermal control, 19288 helps extend gear oil life and protect driveline components across the full HD truck range listed above.
