Semi Truck Repair and Fleet Maintenance You Can Count On

Trucks on the road make money. Trucks in the shop don't. Thunder Mountain Solutions provides dependable semi truck repair and preventative maintenance programs for owner-operators and small fleets in Southeast Arizona.

Mechanical Repair

We provide repair service for Class 7 and Class 8 commercial trucks, covering the mechanical systems that keep your truck operational. We work on most major truck makes — contact us with your make, model, and issue and we'll let you know what we can do.

Preventative Maintenance

Scheduled PM Programs

Preventative maintenance isn't just compliance — it's the most cost-effective way to operate a commercial truck. A missed service interval can turn a $50 oil change into a $5,000 engine repair.

PM Services Include:

  • Oil and filter changes
  • Fuel and air filter service
  • Coolant system checks
  • Brake inspection and adjustment
  • Lubrication and grease service
  • Belts, hoses, and fluid checks
  • Service records and tracking

Why PM Matters

The Smartest Investment You Make in Your Trucks

Thunder Mountain Solutions offers scheduled PM programs designed around your trucks' mileage, hours, and operational demands. We track what's been done, what's coming up, and make sure nothing falls through the cracks.

Avoid Costly Failures

Catching small issues before they become big ones is always cheaper than emergency repairs.

Consistent Service Records

We track what's been done and what's coming up so nothing falls through the cracks.

Maximize Uptime

Trucks that are maintained on schedule spend less time in the shop and more time on the road.
