About Us



We are a performance auto parts online store & repair automotive shop specializing in diesels and off-road vehicles. We offer maintenance services, retail sales, and installation. Our shop is staffed with expert technicians who provide quality repair and maintenance service.

     Starting in 2002, Michael Dunks founded Dunks Performance and began selling parts online while still in college. By 2003, he was able to open his own brick and mortar store In Springfield, Oregon as a one-man owner-operator. Over a decade later, the shop has expanded to include nine employees and six bays with the hope to continue expanding. We are a full-service shop that does anything from your basic oil change to complete frame and up builds.
     We specialize in being #DunksBuilt. What is #DunksBuilt? It is standing out with a quality vehicle that is quality built with quality parts. Diesel performance, LS performance, and suspension work, especially on Jeeps, are just a few of the things we are experts in. Whether it be a 70’s CJ7 or a 2017 JK, a 5.9 Cummins or a brand new Powerstroke, we are the go to shop.
      While we pride ourselves on providing the best experience for our customers, we also like our toys. Some of those toys include an LS swapped Camaro that runs sub-8’s in the 1/4, an LS swapped TJ ready to tear up the sand dunes, or a supercharged JK on Dana 60’s and 40-inch tires. Our reputation as a shop has led us to be fortunate enough to be featured on the cover of Diesel Power Magazine. We have also had multiple features in JP Magazine and Trailer Life Magazine. With a growing following on social media, we have also been fortunate enough to partner with Royalty Core and work on their SEMA vehicles for the past couple of years.
