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.
Engine Overhaul & Custom Builds
We are just as comfortable overhauling a motor back to OE specs and standards as we are performing a full
custom performance engine build. Our staff can point you in the right direction and make recommendations
for your build depending on what the overall goal is and also perform the services to get your vehicle back
on the road in a timely manner.
Fabrication & Welding
We have a dedicated metal fabrication shop adjacent to our main repair facility with a high-tech CNC plasma
table where parts are fabricated for the custom services that we offer including our Mega Cab Long Bed
Conversions. We have built full off-road vehicles and we design and fabricate custom parts on a regular
basis. There is no automotive fabrication welding project that we can’t handle here at DKDiesel Performance
& Offroad.
