Before You Reach Out

Quick Answers.

Stuff worth knowing before you call or drop in. Anything else, just get in touch.

What's the best way to reach you?

Phone is fastest — most calls get picked up live during business hours. If you'd rather type, the message form or chat widget gets answered the same day. Walk-ins are welcome during hours but calling first means we can have a bay and the right parts ready.

What information helps when I first reach out?

Year, make, model, engine, and what's going on with it — even if you're not sure what's wrong. Any codes you've scanned, recent work that's been done, and how long the issue's been happening. The more we know upfront, the better the first conversation goes.

Do I need an appointment?

For repair and tuning work, yes — calling ahead lets us slot you into the schedule and have parts on hand. For a quick look, a question, or a DOT inspection, walking in during business hours usually works.

What if my truck won't start? How do I get it to the shop?

If you can't drive it in, the easiest move is a flatbed tow. We don't run our own tow service but we work with several reliable operators across the area — call us and we can point you in the right direction.

Where exactly are you located?

10007 Old State Highway 73 in Harveysburg, OH 45032. We're between Waynesville and Wilmington, right off SR-73. Plenty of room for trucks and trailers — pull right up.
