Truck Repair in Riverside
Riverside is a working truck town — distribution fleets on the 215, construction trucks feeding job sites in every direction, and owner-operators who cannot afford a truck sitting in a queue. Our Fontana shop, a short run up the freeway, handles the mechanical work Riverside trucks need: diesel engines, transmissions, differentials, chassis and complete truck reconditioning.
Serving Riverside from our Fontana shop
Mechanical truck repair without the dealership wait
We are a rebuild shop: we open components up, find the actual failure, and repair, rebuild or manufacture what is needed. That covers diesel engine work, transmission and differential rebuilding, driveline and chassis repair, and the hydraulic systems on water trucks, crane trucks and work bodies.
Inspection is documented with photos and video and the quote is written before work proceeds — you approve the scope, never a surprise.
