Davis Counties Trusted Diesel Mechanic!


Extreme Auto Service is here to take care of all your vehicles.  Not just gas, but any Light-Duty diesel truck.

  This covers any of your trucks from the new ½ ton diesel to a beastly 1 ton towing your toys or running in your fleet.  Since we are committed to excellence, we have taken the time to ensure we have qualified technicians that know diesels.  Most diesel repair comes with a 2yr/24k mile warranty for peace of mind.

So whether you have a 5.9 Cummins that needs to be replaced, and 6.7 Super-Duty turbo that needs upgraded or maybe a 6.0 that you want bullet proofed, we are here to help with all any diesel concern you might be experiencing. We can also take care of any DEF or high-pressure fuel system issue you may be experiencing. We will also perform our Safety and Reliability Inspection to keep your Ford, Chevy or Dodge truck or diesel car running and safe!

Plus any diesel repair or maintenance you have performed whether personal or fleet will get you entered into our MONTHLY GIVEAWAYS so give us a call or schedule an appointment or pickup today!

" These guys are the real deal. They diagnosed my problem, sent me a detailed report of what needed to be fixed WITH PICTURES OF THE DAMAGED PART, and had the car fixed at a great price.

Thanks to everyone down at Extreme Auto Service"
