Customer Reviews

What Our Customers Say

We take pride in making sure every customer understands what work was done on their vehicle and (most importantly) why. Here are just a few of the customers we've been able to do that for.

I would highly recommend JRB Performance to anyone looking for any kind of repairs or modification work. I had a majority of my steering components on my Ram replaced by JR and I was very happy with the results. I don’t let many technicians touch my truck unless I’m confident they are experienced and are not just in it for the money. JR has a passion for what he does and his work really shows it. I will be returning for future work and I’m more than happy I found someone I can trust.

Phenomenal Communication, great customer service. Our local Landscaping company relies on the service that we get here. Always responsive, reasonably priced and will go above and beyond to help you.

I had a bull bar put on by them. They are very reasonable with pricing and acceptional customer service. The bull bar came out great! Very satisfied with their work. They also checked and repaired rivets in my mud flaps just because I asked. I knew about JRB because my brother needed some repairs done on his vehicle and found them online hoping for honesty and reasonable pricing. That is just what we experienced, both my brother and I. They are very honest and I wouldn't go anywhere else from here on in. They have all services available. I would only recommend JRB to anyone.
