Jason knows his stuff. Most honest guy, easy to talk to, gets problems fixed right; what more can I say.

I just had my Cummins diesel repaired at Xtreme Diesel and could not be more satisfied. Jason is a very hard-working man and spent many hours diagnosing my problems. He was very fair with his prices and time. If you want honest repair this is the place to go. Thanks Xtreme Diesel. YOU ARE THE BEST!

I called Aftershock Performance in Chico and they referred me to Jason at Xtreme Diesel. After our short conversation I felt I could trust him with my baby (truck). After 28 years in law enforcement, I don't do so easily. His price was EXTREMELY fair considering what I was quoted by other places. He's earned a customer here.

We have been doing business with Xtreme Diesel for 10 years and have never once been disappointed with their integrity, honesty and quality. Get it taken care of the right way the first time.

They diagnosed the issue quickly and determined new U-Joints and carrier bearing were needed. They got us in and out of there in the same day so we could get back to work!

Best place I've ever taken my truck to get worked on. I own a Duramax and would trust the guys at Xtreme Diesel with my truck any day of the week. Highly recommended.
