Longview Diesel and Performance

Longview Diesel and Performance is a six-bay diesel shop on Service Drive in Longview, working on Duramax, Powerstroke, and Cummins trucks. The shop splits its work between performance and the everyday: turbo and fuel system upgrades, injectors, CP3 swaps and lift pumps, transmission builds from Stage 1 daily drivers up to competition grade, engine builds with head studs, ARP fasteners and forged bottom ends, plus diagnostics and general repair. In-house fabrication and welding are part of the mix. Fleet work is a big piece of the business, with scheduled preventive maintenance, DOT inspections, service contracts, and priority bay access. The shop puts it plainly on its own site: built for trucks that have to work tomorrow, by techs who run diesel themselves. A quote builder on the website lets customers spec their truck and pick services, then routes it straight to a service advisor who follows up with pricing, usually inside two business days. Shop hours are Monday through Friday, 8:30 a.m. to 5:30 p.m.
