We're a Real Diesel Shop. Not a Call Center.
Interstate Fleet Services has been at 3033 N Cherry Road in Rock Hill for over 26 years. We're not a franchise, not a dispatch center, and we're not going to put you on hold while they find someone who can help. You call us, we answer, and we get to work.
We've built this business one truck at a time — owner-operators who needed someone they could trust, fleet managers who were tired of paying dealer prices and waiting two weeks, drivers stuck on I-77 at midnight with a truck that wouldn't move. That's who calls us. That's who we show up for.
26 years in this business means we've seen your problem before. Probably last week. We diagnose fast, work fast, and charge fair. No job too big — we cover you from A to Z.

“Called at 11pm with a blown coolant hose on I-77. They were there in under an hour and had me back on the road by 1am. Saved my load and my day. These guys are legit.”
