More About the Repairs We Offer

We proudly offer a full range of heavy-duty diesel repair services for vehicles of all types. One of the more common problems is turbocharger failures, often due to oil contamination or wear and tear, which leads to reduced power and efficiency. Injector issues are another frequent problem, causing rough idling, poor fuel economy, and difficulty starting. Exhaust gas recirculation (EGR) system failures can result in increased emissions and engine performance issues. Diesel particulate filter (DPF) clogs can cause reduced power and fuel consumption. Meanwhile, fuel system complications like clogged fuel filters and fuel pump failures can lead to engine stalling and poor performance.  We encourage you to see us at the first sign of a problem to prevent further issues and costly heavy-duty diesel repairs. Combining our specialty equipment with our expert diesel service enables us to get your vehicle fixed and turned around efficiently so you can get back on the road and back to work. We also cover extensive repairs on in frame engines, transmissions and clutches, air breaks, suspensions, drivetrains, turbos, and DEF systems (including diagnostics.)
