JMT Performance

Jake helped me keep my old honda alive. Both he and Chris are very accommodating and have good attitudes and a solid sense of humor. This is a no bs shop, they aren't going to charge you for things you don't need and are 100% dedicated to fixing things to spec and optimum performance. They have lots of knowledge and experience between them and I would recommend anyone to go here.

Driving from Missouri to Colorado when the fuel pump on the car I was driving went out. The Tow driver recommended this place and it awesome. They were able to get the fuel pump and install it on the same day and was able to make it home safely. They were friendly, accommodating and did their best to get me back on the road quickly as possible. Sincerely Thank you!

I highly recommend this repair shop for gas or diesel vehicles. Our truck had an issue on a Friday afternoon towing our fifth wheel rv. I looked up diesel mechanics open on Saturday and JMT Performance came up in the search. I arrived when they opened and Chris went to work on my truck even though he had a garage full of vehicles. After a couple hours, the truck issue was resolved and we could get back on the road the next day. Chris was very neighborly and kind. His rates were reasonable also. He takes an interest in his customers, asking me to let him know when we reached home the next week.

If your looking for a shop in the local area these are the guys! Came in for head replacement on a duramax. From diagnostic, to final repair, they were beyond professional. They are top notch when it comes to communication. Almost daily updates through video, texts or phone calls. Super transparent and very knowledgeable. I can assure you, this is the only place I will take my business when it comes to a mechanic from here on out.

I really recommend this mechanic shop to everyone in the Junction City area, or anyone passing by this town. My family and I were heading to Estes Park in Colorado, with our fifth wheel, when our truck broke down. Thanks to Chris the owner of JMT Performance, our truck was fixed and we were able to continue with our road trip. Very knowledgeable and nice people 👍 😊
