Welcome to St Diesel
At St Diesel, we understand that downtime is not an option for truckers and fleet operators who depend on their rigs every single day. Based in Hesperia, CA, we specialize in Diesel Injector Rebuild services backed by OEM-quality parts and certified technicians who take every build seriously. We are locally owned, which means we take pride in the work we put out and stand behind it with a clear 6 to 12 month warranty on every rebuild. Whether you need Fuel Injectors replaced, remanufactured diesel parts sourced, or full Diesel Repair handled from start to finish, we are built to deliver reliable results. Every injector we rebuild is tested before it leaves our shop, and we back that with a free estimate to get started.
Our in-house process covers everything from Injector Testing and bench verification to injector calibration and Injector Service, so every component meets the standard your equipment demands. We also handle Diesel Engine Parts, Diesel Fuel Pumps, Turbochargers, and Turbo Actuators, giving you a dependable one-stop shop for heavy duty diesel repair needs. For operators focused on Diesel Performance Tuning, our certified technicians bring the same precision and attention to detail to every job. We keep our pricing affordable without cutting corners, and if you find us through our website, we are happy to extend 10% off on a minimum purchase of $600. Reach out to us today for your free estimate and let us get your equipment back on the road, verified and ready to run.
