441 Diesel specializes in diesel engine repair. Our experience and training with today’s modern diesels give us a unique insight into common failures as well as upgrades to prevent these failures. We offer ARP head stud upgrades in all light-duty diesel applications to prevent repeat head gasket issues as well as top-of-the-line machine shop work that ensures when we get your engine parts back from the machine shop they are equal to or exceed manufacturer’s specifications. We offer complete engine rebuilds, engine replacements, fuel system repairs, exhaust upgrades, and extensive turbocharger service. With the introduction of emission systems such as EGR and SCR you need a shop that understands how these systems work and what affect they have on your engine. These systems can not be diagnosed by replacing random parts. That’s why 441 Diesel invests heavily in OEM diagnostic software for all engines we service.
