A little bit about us at Precision Diesel inNewport Beach, CA

Welcome to Precision Diesel, where excellence and reliability converge to keep your fleet on the road and out of the shop. Established in 1999, Precision Diesel began as an in-shop truck and trailer repair business. Over time, our commitment to outstanding service led us to a realization — our customers value on-site service and repairs above the alternative. In response, we shifted our business model exclusively to mobile truck & trailer fleet maintenance, inspections, and repairs, and this has been our focus and specialty ever since.  

Our goal is to reduce the time your heavy equipment sits in a shop waiting for routine repairs that can be easily completed in a day or a few hours at your location.
