Full brake inspections, air brake service, rotor resurfacing, and custom exhaust fabrication for diesel and natural gas powertrains.

Fleet Maintenance Programs

Custom service schedules for multi-vehicle fleets. One point of contact, prioritized scheduling, and detailed service records for every truck.

Emergency Breakdown Service

When your truck breaks down mid-route, we respond fast. On-site diagnostics and field repairs to get you back on the road as quickly as possible.

Inspection & Compliance

DOT inspections, emissions testing, and compliance documentation. We help you stay legal and keep your operating authority clean.

Why Mountaineer

We provide detailed estimates before any work begins. You'll always know what to expect — no hidden fees, no upselling.
