🔧 412 DYNO SHOP IS TAKING ON MORE WORK! 🔧

We’ve added a new technician to the 412 Dyno Shop team, and that means we finally have some more room in the schedule!

We’re now taking in more regular mechanic work — maintenance, repairs, diagnostics, and general automotive work.

If you’ve got a car, truck, or project that needs some attention, give us a call or shoot us a message. We’d love the opportunity to take care of you and your vehicle right here at your local shop.

Thank you to everyone who has supported us and trusted us with your vehicles. We appreciate our local customers more than you know!
