Banks Power Ram-Air Differential Cover Kit

2019–2026 RAM 2500/3500 & 2020–2026 Chevy/GMC AAM 14 Bolt

Part #: 19286

Overview

The Banks Ram-Air® Differential Cover Kit is engineered to deliver superior cooling performance for heavy-duty trucks equipped with the AAM 14 Bolt differential. Designed specifically for 2019–2026 RAM 2500/3500 and 2020–2026 Chevy/GMC models, this satin black cover replaces the stock differential cover to enhance gear life and reduce maintenance costs. By optimizing fluid flow and aerodynamics, the Ram-Air® Cover cools more efficiently than traditional flat-back or high-capacity covers, requiring less lubricant and extending the interval between fluid changes.

Ideal for truck owners who demand reliability and durability during towing, hauling, or off-road use, this cover combines innovative design with proven performance. Banks Power’s patented Ram-Air® technology ensures your differential stays cooler under the most demanding conditions, protecting your investment and improving overall drivetrain longevity.

Key Features

The Banks Ram-Air Differential Cover incorporates advanced engineering to maximize cooling efficiency and durability. Key features include:

• Patented Ram-Air scoops that channel cold, high-velocity air directly into the differential, overcoming the “dead air zone” behind the axle housing.
• Massive external heat radiation fins that dissipate heat rapidly, significantly outperforming flat-back covers.
• Engineered break-away design to prevent damage if the cover snags on obstacles during off-road driving.
• Cooling performance that is 5 times better than flat-back covers in on-road towing tests and 118% better in sustained high-speed tests.
• Dry-mount high-pressure silicone O-ring seal for a clean, mess-free installation without the need for RTV sealant.
• Internal heat transfer fins that move heat from the fluid to the external fins for maximum cooling efficiency.
• Designed to clear spare tire heat shields, Panhard bars, and other suspension components without sacrificing ground clearance.
• Durable satin black finish that resists corrosion and complements the rugged look of your truck.
• Limited lifetime warranty backed by Banks Power’s decades of engineering excellence.

Construction & Design

The Ram-Air Differential Cover is crafted from high-quality materials engineered for strength and heat dissipation. Its robust construction withstands harsh road conditions and off-road impacts while maintaining optimal thermal performance. The cover’s aerodynamic shape and patented scoop design actively direct airflow to critical areas, ensuring the differential fluid remains cooler during heavy loads and extended drives. The precision-machined sealing surface and silicone O-ring provide a reliable, leak-free fit that simplifies maintenance.

Performance & Sound

By dramatically improving differential cooling, the Banks Ram-Air Cover helps maintain optimal lubricant viscosity and gear temperatures, reducing wear and extending component life. Cooler operating temperatures translate to improved drivetrain efficiency and reliability, especially during demanding towing or hauling scenarios. While primarily focused on thermal management, the cover’s aerodynamic design also minimizes drag and airflow turbulence around the axle housing.

Installation & Fitment

Installation is straightforward and designed to fit directly onto the AAM 14 Bolt differential housings found on 2019–2026 RAM 2500/3500 and 2020–2026 Chevy/GMC trucks. The kit includes all necessary hardware and a silicone O-ring seal, eliminating the need for messy RTV sealants. No modifications to the vehicle or suspension components are required, and the cover maintains factory ground clearance and compatibility with spare tire heat shields and Panhard bars.
