Banks Power Ram-Air Differential Cover Kit

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

Part #: 19287

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 innovative cover outperforms stock and aftermarket flat-back covers by efficiently managing heat buildup in the differential housing. Ideal for truck owners who demand durability and reliability during towing, hauling, or off-road use, the Ram-Air® Cover extends gear life by reducing operating temperatures and minimizing lubricant consumption.

With a patented design focused on fluid dynamics and aerodynamics, this differential cover provides a significant upgrade in cooling efficiency, helping you save money on fluid changes and maintenance over time. Banks Power’s commitment to performance and quality ensures this product meets the highest standards for rugged applications.

Key Features

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

• Patented Ram-Air scoop design that channels cold, high-velocity air into the differential housing, overcoming the “dead air zone” behind the differential.
• Massive external heat radiation fins that dissipate heat rapidly, improving cooling efficiency by up to 118% compared to flat-back covers in sustained high-speed tests.
• Engineered break-away tabs that protect the cover from damage if snagged on obstacles during off-road driving.
• Dry-mount high-pressure silicone O-ring seal for a clean, reliable installation without the mess of RTV sealants.
• Internal heat transfer fins that conduct heat from the gear oil to the external cooling fins for enhanced thermal management.
• Designed to clear spare tire heat shields, Panhard bars, and other suspension components without sacrificing ground clearance.
• Proven to cool 5 times better than traditional flat-back covers in real-world on-road towing conditions.
• Limited lifetime warranty backed by Banks Power’s decades of engineering expertise.

Construction & Design

The Ram-Air Differential Cover is crafted from high-quality materials engineered for strength and thermal conductivity. Its robust construction withstands harsh environments and heavy loads while efficiently transferring heat away from critical gear components. The cover’s aerodynamic shape and integrated scoops are the result of extensive testing and innovation, culminating in a patented design that sets a new standard for differential cooling solutions.

Attention to detail in sealing technology ensures a leak-free installation, while the break-away design protects the cover from damage without compromising structural integrity. This combination of durability and advanced thermal management makes the Banks Ram-Air Cover a reliable upgrade for demanding truck applications.

Performance & Sound

By significantly reducing differential operating temperatures, the Banks Ram-Air Cover helps maintain optimal gear oil viscosity and reduces wear on internal components. This results in extended gear life and improved drivetrain reliability, especially under heavy towing or sustained highway speeds. The enhanced cooling performance also means less frequent fluid changes, saving time and maintenance costs.

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 a high-pressure silicone O-ring seal, eliminating the need for messy RTV sealants and simplifying the installation process. No modifications to the vehicle’s suspension or clearance are required, and the cover clears common components such as spare tire heat shields and Panhard bars.
