Great customer service and a very fair price. Offers Jasper Engines and Transmission products.

Stopped in today to service a 2005 Chevy Silverado (6.6 Duramax) I just bought. I spent less in parts than if I was to do it myself (like I normally do)! At the end of the service when it was time to pay not only was a surprised by the bill being a reasonable price I was update on where my truck stood mechanically and what I would need to replace soon.

Definitely recommend and will be my go to place for any more work and/or service I need done!

I had a charging issue with my 2005 Ford f350 dually I called rocks they told me if I could get it in that day they look at it the following morning.
They called the next day at noon and said the truck was done the price was really good the work was really good and I plan on taking it back there if ever need be

I have a 2009 F-350 6.4. These trucks suffer from many issues. Loren found problems that the dealership couldn't figure out after they had my truck for months. It took Loren a few hours ! What they charged for the repair was extremely reasonable. If you have a diesel that needs repaired ,give these guys a try , you won't be disappointed.

Took me truck in a week or so ago for a blown carrier bearing. Work was turned around quick and the price was great. Helpful staff, they let me know about a few other issues I asked them to look at and I will be bringing my truck back to them for those as well. Great staff, friendly and professional. Highly recommended. I wouldn't take my truck anywhere else in the valley.

Great service. These folks are now my go to mechanics for my Dodge 3500.

Awesome place! I needed a few things done and inspected and they took care of it in only a couple days. Good customer service, real nice people. If I need anything done in the future this is the place I will go. My truck runs great, I have no complaints.

We traveled to Alaska from Arizona helping our son move. When we got to Palmer our Ford F250 started giving us trouble. We needed to leave the next day to go home and it didn't look promising. Called Roks Diesel, told them our problem. They made an opening for us, found out it needed a new EGR valve. They had us running again in 5 hours. Thank you so much!!! We made it back to Arizona safe and sound!!

Loren figured out a complex electrical issue when no one else could. He simply fabricated a new wiring harness in the shop instead of throwing countless thousands of dollars at the problem in replacement parts. This issue was with a Cummins 6.7, but in the past he did great work on a turbo issue on my Duramax . I won't go anywhere else in AK for diesel work.
