"Took my LBZ in for a Kryptonite kit and a tune. Truck drives tighter than the day I bought it and pulls way harder. These guys actually know Duramax stuff cold."
Reno, NV • Duramax Owner
"Had S&B fuel tank, FASS lift pump and a transmission rebuild done. Clean install, fair price, and they walked me through every step. Won't take my Cummins anywhere else."
Sparks, NV • 6.7 Cummins
"Honest shop. Diagnosed my 6.0 Power Stroke correctly the first time after another shop strung me along. EGR cooler + head studs done right. Truck's a beast again."
Carson City, NV • Power Stroke Owner
Sierra Nevada Diesel Performance was built on a simple idea: Northern Nevada's truck owners deserve a shop that takes diesels as seriously as they do. We started small — a couple of techs who lived and breathed Cummins, Power Stroke and Duramax — and grew by doing right by every customer who rolled in.
Today we run a full-service facility with dedicated diesel bays, dealer-level diagnostic equipment, and a parts network that gives our customers access to the best aftermarket gear in the country. Whether you're towing across the Sierras, daily-driving a one-ton, or chasing 1,000+ horsepower on the dyno, we've got you.
Located right off I-80 in Reno. We answer the phone fast — usually first ring.
