aFe STREET SERIES Rear Differential Cover

2021–2022 Ford Bronco 2.7L & 3.0L V6

Part #: 46-71290A

Overview

The aFe STREET SERIES Rear Differential Cover for the Ford Bronco is designed to enhance the durability and cooling capacity of your vehicle's rear differential. Crafted with performance in mind, this cover features a raw finish with machined fins that not only provide a rugged, aggressive look but also serve a critical function in heat dissipation. Whether you're off-roading, towing, or enjoying spirited driving, this differential cover helps support your vehicle’s differential under demanding conditions.

Built for enthusiasts who seek improved oil capacity and superior thermal management, the STREET SERIES Differential Cover ensures your differential stays cooler and operates efficiently over extended periods. Its increased oil capacity helps maintain proper lubrication, reducing wear and tear during high-stress driving scenarios. The integrated fins transfer heat away from the oil, helping to prevent overheating and maintain optimal operating temperatures, which can contribute to longer differential life and more consistent performance.

Key Features

The aFe STREET SERIES Differential Cover incorporates several innovative features designed to maximize performance and protection:

• Constructed from durable, high-quality materials with a raw finish and machined fins for enhanced heat dissipation.
• Internal and external fins transfer heat from the differential oil to the outside air, promoting maximum cooling during demanding driving conditions.
• Increased oil capacity compared to stock covers, supporting better lubrication and reducing the risk of overheating during extended use.
• Built-in magnetic drain plug captures loose particles and metal shavings, providing critical protection for your differential components.
• Factory-calibration plug maintains the correct oil level, preventing overfilling and ensuring proper operation.
• Designed specifically for the Ford Bronco (2021–2022), ensuring a perfect fit and straightforward installation.
• Heavy-duty construction with precision machining for a seamless fit and long-lasting durability.
• Corrosion-resistant finish suitable for off-road environments and harsh conditions.

Construction & Design

The aFe STREET SERIES Differential Cover is engineered with a focus on durability and thermal management. Made from high-strength materials, it features a robust design that withstands impacts and rough terrain. The cover's unique internal and external fins are precisely machined to maximize surface area, facilitating efficient heat transfer from the differential oil to the surrounding air. This design helps maintain lower operating temperatures, which is essential for off-road adventures or heavy-duty towing.

The increased oil capacity is achieved through a carefully designed internal chamber, providing additional lubrication volume that helps reduce friction and wear during prolonged or aggressive driving. The magnetic drain plug is embedded with high-quality magnets to attract and hold loose metal particles, preventing them from circulating within the differential and causing damage. The cover's overall construction ensures a secure, leak-free seal and easy maintenance access, making it a reliable upgrade for your vehicle's drivetrain.
