built on diesel & dedication

Most are working adults in rural or semi-rural communities who value skilled technicians, honest diagnostics, quality parts and quality work done right. Whether maintaining a work truck or investing in performance upgrades, our customers are looking for a trusted, long-term service relationship rather than quick or discount repairs.

why dierks diesel
At Dierks Diesel & Auto Performance, we believe trust is built through honest work, skilled craftsmanship, and mutual respect. From the moment you walk through our doors, we aim to create an environment where customers feel welcomed, heard, and valued—more like visiting family than just dropping off a truck at a shop.
We use high-quality parts and proven repair practices because reliability matters. Whether we’re maintaining a work truck that supports your livelihood or building performance upgrades with real-world purpose, we focus on doing the job right the first time. We take the time to diagnose issues accurately, explain your options clearly, and recommend solutions that make sense for how you actually use your truck.
As a family-owned, locally rooted shop, we understand that downtime affects more than a schedule—it affects people and families. We stand behind our work, communicate openly, and treat every customer with the same care and respect we expect ourselves. Our goal is to be the shop you trust for years to come, where relationships matter and quality is never compromised.
