I have nothing but good things to say about this shop. Very professional. They helped me fix my ear, def and exhaust. I highly recommend. Great people.

Chris is a amazing mechanic. I don’t believe there’s any one better. I would recommend him for any work on your truck he has always treated us awesome. Chris treats you like family and really cares for his customers. I have had 2 of my Truck’s to Chris and they both run awesome and my third is on it’s way. Thankyou Chris for everything brother.

Chris hooked me up with a sweet 5exhaust kit and changed out the front axle seals on my 2012 3500.Next on the list will be more suspension, see you soon. Thanks

I have nothing but good things to say about Mauntain Side Diesel. Great service at a great price.

Came to the shop for basic maintenance as well as some ARP head studs and some new injectors. Chris has great knowledge and recommendations for everything from oil to the best power upgrades. If youre looking for performance, Mountainside is the place to visit.

Great customer service. Work was quick, efficient, and well done! Definitely recommend!

Professional service provided with quality work, have been here twice and will be back for future work on my truck when needed.
