24-Hour Rush Repair
Covering Los Angeles out of our Fontana shop
Truck Repair in Los Angeles
Hardly anywhere on the planet handles freight on the scale Los Angeles does, and its trucks — port and regional tractors, vocational dump and water trucks, delivery fleets — make no money sitting still. We repair those trucks at our Fontana shop and cover LA with free pick-up and delivery: engines, transmissions, differentials and gears — the work this shop was founded on — along with aftertreatment, chassis repairs and working hydraulics, everything under one roof.
Covering Los Angeles out of our Fontana shop
The complete truck — never just the fault code
For Class 8 tractors, vocational trucks and medium-duty fleets we handle in-frame engine jobs, transmission and clutch attention, differentials rebuilt in-house, DPF/SCR aftertreatment and derate problems traced by measurement, PTO and wet-kit hydraulics, brakes, air systems and suspension. Peterbilt, Kenworth, Freightliner, International, Mack, Volvo, Hino, Isuzu and Ford each have a dedicated page describing what we do for that line.

We take the unit apart and assess the full extent of the failure.

Condition and findings get recorded, so the repair conversation stays clear and honest.
Written quote
The work we recommend gets defined and priced before anything proceeds.
Your approval
Scope, urgency and the sensible way forward get confirmed with you.
Making & rebuilding
Components get machined, welded, rebuilt or reverse-engineered as the job requires.
Testing
Operation and workmanship are verified before anything is released.
Return
The finished component or machine goes back into service with you.
Questions customers ask us
Is your shop located in Los Angeles?
It is not — we are based in Fontana. Los Angeles truck owners and fleets are served from there, and pick-up and delivery are free when applicable.
Will you accept fleet work out of LA?
Yes — one truck or an entire fleet, and each unit receives a documented inspection plus a written quote.
How do I find out what a repair will cost?
There is no charge for a quote. Call (800) 821-3404 or (949) 400-2937 — once the truck or component is in front of us, we record the failure on photos and video and price the job in writing before anything begins.
