Our Specialties
Full-scope diesel and trailer service, done wherever your equipment is parked.
Dealership-Level Diagnostics
Advanced computer diagnostics for engine, aftertreatment, transmission and ABS faults — the same depth of troubleshooting you would get at a dealer, right where your truck sits.
Diesel Engine Repair
Diagnostics, fuel system, turbos, injectors, cooling, belts and hoses. We find the real problem the first time.
Brake Service
Air brake repair, adjustments, drums, shoes, chambers and slack adjusters — keep DOT-ready and safe.
Electrical & Lighting
Starters, alternators, batteries, wiring faults, trailer lights and ABS circuits.
Trailer Repair
Axles, bearings, suspension, landing gear, doors, floors and reefer-trailer mechanical support.
PM & Oil Service
Preventive maintenance programs, oil and filter changes and inspections that stop breakdowns before they start.

Common Questions
Are you really certified, and can you diagnose like a dealer?
Yes. Our technician is ASE World Class certified and equipped for dealership-level diagnostics, so tough fault codes and electrical gremlins get solved on site instead of being sent to a dealer.
What types of vehicles do you work on?
Heavy and medium duty diesel trucks and commercial trailers — tractors, box trucks, dump trucks, flatbeds, dry vans and more.
Do you offer emergency service?
Yes. Call anytime for a breakdown and we'll get to you as quickly as we can. After-hours calls may carry an emergency rate.
How much does a service call cost?
We quote before we turn a wrench — a call-out fee plus labor and parts. No surprise bills.
Can you handle fleet maintenance?
Absolutely. We set up recurring PM schedules and priority service for fleets of any size.
What forms of payment do you accept?
Card, ACH and company checks for approved fleet accounts. Details provided with your quote.
