We have been doing business with Extreme Diesel for 10 years and have never once been disappointed with their integrity, honestly and quality. They might not be the cheapest mechanic in Chico but you get what you pay for folks. Get it taken care of the right way the first time.

Great experience at Extreme Diesel. Originally thought the torque converter was going but they diagnosed the issue quickly and determined new U-Joints and carrier bearing were needed to bring the driveline back to par. They got us in and out of there in the same day so we could get back to work! Big thank you to the staff and owner

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