Peterbilt Truck Repair in Fontana
Peterbilts are the trucks owners keep for decades — 379s and 389s still earning daily, 579s running regional freight, 567s on vocational work. Our Fontana shop repairs Peterbilt trucks across every system: Cummins and PACCAR MX engines, Eaton and automated transmissions, aftertreatment, axles, suspension and chassis. Independent shop, not a Peterbilt dealer — heavy-truck work done to a rebuild standard, with machining and gear manufacturing in the same building.

Peterbilt work we do every week
In-frame engine work on Cummins ISX/X15 and PACCAR MX-13; transmission and clutch service; DPF/SCR aftertreatment diagnosis and derate tracing; differential and driveline rebuilding (gears are this shop's founding trade); air system, brake and suspension work; and the frame, fifth-wheel and body-mount repairs working trucks accumulate. A Peterbilt is a long-term asset — we repair it like one.

Regular hours Monday–Friday, 6 AM–5 PM — and the 24-hour rush line runs every day of the year, because trucks earn nothing parked.
