Heavy Truck
Your heavy truck and trailer experts for parts, service, fabrication, and repair.
We work with heavy-duty diesel and highly specialized vocational trucks, supporting repair, custom modification, fabrication, welding, body modification, parts, and unique service applications.
We serve fleet operators, contractors, municipalities, agricultural customers, and businesses that rely on heavy-duty vehicles to stay productive, compliant, and on the road.
Heavy truck work has been a core part of the Dentoni’s name for more than 65 years, and a hub of production in Stockton, California, growing from early welding and fabrication into the specialized truck service, repair, and modification support customers depend on today.

Fabrication & Machine Shop
Not every repair is solved with a catalog part. When a truck, trailer, or vocational body needs something more specific, our team has the fabrication and machine-shop knowledge to keep the job moving.
We support heavy truck repairs with specialty U-bolts, driveline work, hydraulic cylinder support, lathe work, welding, friction relining, custom brackets, structural repair, and practical modifications.
Our in-house capability gives us more options when a standard replacement is not enough. Instead of stopping at “we can’t get that,” we look at the part, the application, and the repair as a complete system, then build or modify what the job calls for.
