BD Diesel Differential Cover

2003–2018 Dodge Ram 2500 / 3500 5.7L Hemi, 5.9L Diesel, 6.4L 392, 6.7L Diesel

Part #: 1061825

Overview

The BD Diesel Differential Cover is engineered to enhance the durability and longevity of your Dodge Ram or Chevy Duramax differential. Designed specifically for heavy-duty diesel and gas-powered Ram trucks from 2003 through 2018, this cover improves lubrication efficiency by directing oil flow precisely where it’s needed most. Unlike bulky aftermarket covers that can cause oil to be flung off the ring gear, BD Diesel’s innovative design deflects oil back onto the ring and pinion gears, reducing heat buildup and wear.

This differential cover is ideal for truck owners who demand reliable performance and extended drivetrain life under tough driving conditions, including towing, hauling, and off-road use.

Key Features

BD Diesel’s differential cover offers a range of benefits that protect and optimize your vehicle’s rear differential:

• Precision-engineered oil deflection design keeps lubricating oil on the ring and pinion gears
• Reduces heat buildup for cooler operation and longer component life
• Fits a wide range of Dodge Ram 2500 and 3500 models from 2003 to 2018, including diesel and gas engines
• Compact and efficient design avoids the bulkiness of other aftermarket covers
• Durable construction built to withstand heavy-duty use and harsh environments
• Helps maintain optimal gear lubrication under high load and severe duty cycles
• Direct replacement for factory differential covers with no modifications required

Construction & Design

Manufactured from high-quality materials, the BD Diesel Differential Cover is built to endure the rigors of demanding applications. Its robust construction ensures resistance to impacts and corrosion, providing long-lasting protection for your differential housing. The cover’s internal design is carefully engineered to channel oil flow efficiently, maximizing lubrication coverage on critical gear surfaces. This thoughtful engineering reduces friction and heat, which are primary causes of premature gear wear and failure.

Installation & Fitment

Installation is straightforward and designed to be a direct bolt-on replacement for the factory differential cover on compatible Dodge Ram 2500 and 3500 trucks. No special tools or modifications are necessary, making it an accessible upgrade for both professional mechanics and experienced DIY enthusiasts. Proper gasket sealing and torque specifications should be followed to ensure leak-free operation.
