Since 1988, Precision Truck and Trailer Repair has been Salt Lake City's one-stop shop for heavy-duty repairs. We handle everything from diesel and trailer repairs to inspections and fleet maintenance, all under one roof.
We're not a franchise. We're a family. Every truck that rolls into our bay gets the personal attention and expert care that's kept fleet operators and owner-operators coming back for nearly four decades.
Most shops specialize in engines OR trailers OR inspections. Precision does all three — full diesel repair, complete trailer service, and DOT/state inspections in one place.
7 days a week, extended hours from early morning to late evening, and 24/7 mobile service. Breakdowns don't wait — neither do we.
Custom preventive maintenance programs, priority fleet scheduling, and long-term partnerships that go beyond one-off repairs. We keep your entire operation moving.
A lot of diesel shops come and go. Precision has been here since 1988 — family-owned, locally trusted, with an established reputation you can count on.
"Precision has been a godsend for us. We are a company with very custom trucks that require a high level of attention. We have a mid sized fleet and Alyssa and Bob have rescued us from poor fleet management and multiple vendors trying to figure out how to fix them. I cannot say enough good things about them. Honestly I will be using them until I am no longer in charge of the fleet and wherever I go I will still use them."
"Our straight truck had a broken weld on the box. We spoke to several local shops here in Salt Lake. Honestly, this shop was the first one that dealt with us as human beings versus a corporate approach. They listened, found a solution, got a custom piece made for the repair and had it installed within a couple of hours. Bay was amazing. He helped move this forward. We will come back to this shop without question."
"Ashley and Roberto were above and beyond accommodating. Our semi truck had an issue with the fifth wheel spring and we were stuck hauling any loads. They came right away, inspected the truck and got our parts the very next morning. Exceptional service, caring, good work. As a previous owner operator I can say I have met only a few family owned businesses that operate at such excellence."
