About Us

Built On Hard Work And Trust

Ruiz Diesel Service is a family-owned and operated business based in Tracy, CA. When you call, you’re speaking directly with Alejandro, the owner—not a service writer or call center. That means clear communication, faster decisions, and no runaround.

You rely on your trucks to keep your business moving, and you deserve a repair shop that treats your time and equipment with the same level of importance.

Practical, Efficient Repair Approach

Our setup is designed to handle real-world demands. Most of the work is done outside, giving us the flexibility to work on heavy-duty trucks and trailers without the limitations of a traditional shop. This allows for quicker turnaround times and more efficient service.

We work with both fleets and owner-operators, providing dependable repairs that help reduce downtime and keep your operation running smoothly.

If you’re looking for a diesel repair shop that values your time and delivers straightforward service, call 209-481-5638 and let us know how we can help.

More Than Just Truck Repair

In addition to diesel truck repairs, we also specialize in trailer repairs. That means you can address multiple issues in one place instead of coordinating with multiple shops.

From minor fixes to major repairs, the goal is simple—get your equipment back on the road as quickly and reliably as possible.
