🚛 Fleet Maintenance That Actually Saves You Money

Fleet maintenance isn’t just about oil changes… It’s about avoiding those calls.
You know the ones: breakdowns, delays, missed routes, and unexpected repair bills.

Iron Buffalo helps you stay ahead of all of it.

Whether you’re running delivery vans, vocational trucks, or long-haul semis, we build maintenance programs based on how your fleet actually operates, not generic timelines.

As a full-service heavy-duty repair shop in Denver, we don’t just maintain your fleet, we manage it, monitor it, and fix issues before they turn into downtime.

What We Handle for You

✅ Preventive maintenance (PM) inspections
✅ Oil & filter changes
✅ Transmission & differential service
✅ Brake inspections & replacement
✅ Suspension & steering checks
✅ Battery testing & replacement
✅ Lighting & electrical checks
✅ Fluid analysis & top-offs
✅ DOT inspection prep

Why Fleets Choose Iron Buffalo? Because reactive maintenance is expensive. We track service intervals, monitor performance, and build custom schedules that prevent breakdowns, not just respond to them.

And if something does come up?
We’re a one-stop shop. No sending your trucks to multiple vendors. No wasted time.

🚛 Less downtime. Fewer surprises. More miles.

Heads up, fleet managers — DOT Blitz Week is May 12–14. 🚨

The 2026 CVSA International Roadcheck is coming up fast. During this 72-hour period, inspectors across Colorado and North America will be ramping up commercial vehicle inspections with a focus on:

🔍 ELD compliance & hours-of-service logs
🔍 Cargo securement
🔍 Driver documentation (CDL, medical cards)
🔍 Pre-trip inspection items

Expect increased activity at weigh stations, mobile patrols, and rest areas, and keep in mind inspections typically pick up in the days before and after as well.

If your fleet isn't inspection-ready, now is the time.

Iron Buffalo performs full DOT pre-inspections to make sure your trucks, drivers, and documentation pass with confidence, not luck.
