BD Diesel is your number one manufacture of aftermarket and replacement products for Chevy/GM Duramax powered vehicles. With one of the largest assortments around, BD has the right part to get you going when you are broken down, want to make some improvements or looking for some extra performance. BD Diesel has a huge network of dealers, distributors and installers across North America to get you quick access to what you need for your Duramax to get you traveling down the road again. BD Diesel does not just make products for diesel engines - the BD Power line of products are designed to work on both gasoline and diesel Chevy, GM, Buick and Pontiac powered vehicles.

We here at BD are excited about the performance potential of the L5P Duramax engine and our products that have already been released or that are in development. BD also has OE or better quality replacement parts for the fuel system and transmission.

BD transmissions are not just a standard rebuild, each transmission is remanufactured with extra improvements to stand up to the higher weights you tow or the extra horsepower you push through it. For those whom push the limits even further, converter and shaft options are available to take on the demand. A range of pressure and lock up controls help prevent slippage, and, flex plate designed to take on the load. A BD transmission and converter were used by Derek Rose during his 2019 UCC winning run! For those whom are looking to build their own unit, we have Build-It kits that include the some of the same parts we use in our own reman assemblies.
