Description
Keep your rear end looking cool and RUNNING cool with this replacement rear differential cover from BD! No, not all aftermarket differential covers are created equal. Most aftermarket differential covers are excessively large, resulting in lubricating oil being literally flung OFF the ring gear, exactly the opposite of what you need. BD's design deflects oil back onto the ring gear and into the pinion gear, resulting in a cooler, longer life.

About BD-Power

BD Diesel is known as one of the originators of diesel performance because theyve been there since the very beginning. Its by no coincidence that theyve been in the industry since 1972 where theyve seen competition come and go over the years. You could consider them a front to back organization in which they design and manufacture products ranging from Super B Turbo Kits and performance injectors for your Cummins to heavy duty transmissions, torque converters, and other transmission components for your Duramax to Positive Air Shutdowns and exhaust brakes for your Powerstroke and everything in between. Quite literally, there are VERY few components that BD does not build for nearly every light duty diesel application.

BD DIESEL PERFORMANCE

Originally founded in 1972 as Valley Fuel Injection that specialized in fuel injection rebuilding and calibrating, BD Diesel gained the most notoriety beginning in 1989 with the release of their first exhaust brake designed for Ram trucks with the acclaimed 12 Valve Cummins engine. BD would later rename Valley Fuel Injection to BD Diesel Truck Service and Performance Center that operates as an extension to BD Diesel Performance. Today, they operate out of a 65,000 square foot facility in Abbotsford, British Columbia and employ over 100 highly skilled individuals. They are constantly pushing the envelope with forward thinking products that not only fill voids in the marketplace, but also take existing products and push them to the next level.

BD DIESEL TRANSMISSION UPGRADES

Transmissions have a singular but ambitious challenge - to transfer all the torque from the diesel engine to the drive wheels. This must be accomplished while maintaining shift quality and minimizing NVH (Noise, Vibration, and Harshness). With stock or OE configurations, this capacity challenge is somewhat less than extraordinary. Comparatively, a high output diesel that develops 2-4 times the original engine torque and keeping stellar driving characteristics at this power level becomes a new feat. Utilizing the latest technology in CAD and FEA simulation, BD can predict and eliminate failures before they happen. The dedicated team of BDs Transmission and Torque Convertor Department are true experts in the development and analysis of the diesel transmission.

BD EXHAUST BRAKES

BD built its reputation on exhaust brakes starting in the early 90's with many casting designs for both engine and remote mount air actuated systems. Rugged cast-iron bodies with an offset stainless steel butterfly build peak efficiency quickly.

BD TURBO UPGRADES

The turbocharger industry is a special industry for BD and remains a key technological asset. When looking at BDs experienced staff, the majority of their key staff members have been developed in or around this technology. BD focuses on the customer's needs, whether it is fast turnaround, state of the art compressor wheels or turbine wheels, they look to deliver on the highest expectations. You can be assured that a BD turbocharger has been hand crafted to the greatest standards. Using precision lathes, milling equipment, honing machines, and inspection CMMs your turbocharger is continuously graded to exceed the OEMs specifications.

BD FUELING UPGRADES

Owing to its heritage as a diesel fuel systems specialist, BD Diesel Truck Service & Performance Center is a factory-certified Bosch, Stanadyne, Delphi and Zexel calibration and repair lab. They are one of a select few injection shops in North America to have Bosch Common Rail parts and an overhaul and testing franchise. BD Diesel rebuilds most all mechanical and electronically-controlled fuel pumps and injectors for diesel engine applications.

BD ELECTRONICS

Throughout the automotive industry, electronic technology has become an integral part of the OEM solution. Whether it is safety, performance, or driving improvements, BD Diesel Performance has developed a strong electronic department to focus strictly on this technology. By focusing on the core needs of the customer, they engineer out the possible product failures and maximize key features to deliver a top to bottom solution. Utilizing state of the art manufacturing equipment, BD maximizes value and minimizes time consuming tasks that inflate costs. Vehicle electronic technology will remain a key technology at BD Diesel Performance.

Heath (5/5)

Yup I would buy it again if I need one

"Great cover holds little more fluid keeping it close to the gears"

Douglas (5/5)

Fits full size spare

"This BD diff cover looks good and fits good I like the built in o ring makes install simple all (no leaks) all hardware was included. Ultimately I chose this one because the low profile on top fits a full size spare (285 75 16) with no rubbing."

Jill G. (5/5)

Yes I would buy this cover again ,

"Very Nice Diff Cover , Looks good , Functionally it has a drain plug on the bottom . The design on bottom part of cover is closer to the ring gear , which throws more gear oil onto ring gear where it is needed . Its aluminum which should keep the fluid cooler than the stock stamped sheet metal or tin . make sure you oil the rubber gasket into the grove cut into the cover for a good seal . Easy installation . make sure your differential housing is free of dirt and scale ."

Kelly M. (5/5)

Easy installation & looks great. Nice having drain plug

"2012 Ram 3500 105000,miles utility bed crane body 12500lbs Every day of it's life & some times with loaded trailers. Trying to help my differential stay cool & last."

Catherine F. (5/5)

Functional and easy to install.

"Great diff cover. Very heavy duty and comes with everything to install. Just by looking at it you can tell it adds more fluid and better cooling principals than the factory sheet metal piece."

Katie F. (5/5)

I like this differential cover because it's n. . .

"I like this differential cover because it's not deep all the way from top to bottom. It's only deep in the sump area where more oil is needed. Which makes it easier to bolt back up the brake line brackets and the parking brake cable goes back in without having to do modifications."

Q&A

How much capacity does the BD Diff cover add to a 16 Ram 2500?
The BD cover will increase capacity approximately 0.7L.
Will this fit 2016 ram 2500 with factory air ride suspension?
As of today (12/3/2024), we, nor the manufacturer (BD-Power) have test fit this cover on a truck with factory rear air ride so we cannot confirm if it will for sure fit with the factory rear air ride.
Is this made of steel or aluminum?
This is going to be made out of a cast Aluminum. -Mark
I have an '08 Chevrolet 2500 with a 6" lift and 35x12.5R20 tires and wheels. My current ATS diff cover sits too far out to hang a full sized 35" spare tire in the factory location. Will this new diff cover have the clearance for a full sized 35" spare under the vehicle?
Hi Andrew While the BD cover has a much slimmer profile, it still does stick out a bit on the bottom. The bottom portion of the cover will protrude 4.272" from the face of the axle housing. Hope that helps. -Ben
