This shop is fantastic. Jim delivers old school customer service with a great job at a fair price. I've had two of my trucks in there and was impressed both times with both the service and results. Shops like this are far and few between these days.
Near 4 years before I needed this guy. The first time was the best, it lasted 2 months shy of 4 years. He aligned my whole truck and torqued all my bearings to spec, then this past month M&K had to replace a wheel seal, what a joke, "to tight" and I could tell, made a appointment within days I had my truck rolling as smooth as before. Thanks Jim, miles of smiles.
Very flexible and easy to work with. Great value as well. Owner is overly friendly so be prepared to be treated like a person. I bring them my whole fleet for work. Couldn't recommend them more.
Awesome customer service. These folks really know what they are doing. Honest and great attention to detail. I live in Georgia, and find loads to this area for suspension and steering work.
Had Jim's crew do a 3 axle alignment turns out we had a really bad steer tire so they got us fixed up. We couldn't be happier. Thank you for everything, we will be back.
Jim's fantastic, reasonable pricing. Quick and accomidating.
