Welcome to SpecializedDieselNW.com



Our New Website is Live!

Specialized Diesel Northwest's new website is up and we couln't be more excited! Our website will continue to grow daily so if you don't see parts listed for your truck, please call us--as we have access to more parts than our website currently displays. While we're already considered one of the most reputable shops for light diesel truck repair and performance upgrades in the Northwest, our new goal is to become one of the leaders in online diesel performance parts sales. Help us make this goal possible by ordering parts from your new #1 Source for diesel performance parts!

What Makes Us Different?

Rather than just managing our website and shipping out parts when orders come through, we live and breathe diesel engines and pride ourselves in being diesel mechanical experts. We spend our days wrenching on diesel trucks, our nights researching the latest diesel performance technology, and our weekends tearing up the drag strip with some of the most powerful diesel machines in the country. Our future SDNW Diesel Race Truck, a.k.a. #ProjectBlackAndYellow, will have real-time updates on our site as well!

Full-Service Light Diesel Repair and Performance Upgrade Shop

Whether your diesel work truck needs an emergency repair so you can finish your job on time, or you're looking for a little more performance out of your personal rig, SDNW's friendly and knowledgeable staff can take care of all of your needs in one stop--especially now with our new website. Upgrades have never been easier: find the parts you need/want for your truck through our site, have us install them, and drive away from our shop knowing that professionals installed the parts properly and that your truck is going to perform better than it did when it left the factory.
