Our Services

Here at DKDiesel Performance & Offroad, we are more than an online retailer. We are also a full-service diesel and gas repair facility located in Bellingham, Washington. We offer many in-house services that set us apart from our competition and truly make all of your repair needs a one-stop experience. Whether we are building you one of our exclusive custom DKDiesel Performance Transmissions or doing a full cylinder head rebuild or maybe a full custom fabrication build is more what you had in mind, we can accommodate you with our full crew of expert technicians and knowledgeable customer service professionals.

Custom DKDiesel Built Transmissions

Each DKDiesel Transmission is built in-house using only the best parts that are proven to perform and last. We build transmissions for Ford, GM, and Dodge Ram and we offer rebuild packages for different power levels. We can also do purpose-built transmissions for competition or heavy towing applications.

Cylinder Head Machining Services

We have a state-of-the-art Rottler Surfacer that is capable of less than 10 Ra to accomodate the MLS gaskets that are used in all newer diesel and gas engines. We also have a state-of-the-art Rottler machining center for all other cylinder head overhaul and repair operations including valve seat replacement and machining. We also do cylinder head pressure testing in-house.
