Jason at Devil Mountain Diesel / Bay Area Raptor Repair was great to work with. I brought in my 2022 F-150 Raptor 37 after struggling with a stubborn "Drive Control Fault, Service Required" issue that started after a ride height calibration attempt. The Ford dealer couldn’t figure it out and couldn’t get the truck into Engineering Test Mode. Jason diagnosed and fixed the VDM issue in just half a day, something the dealer couldn’t resolve. His knowledge of the Raptor’s suspension and electronics is outstanding. The repair was done quickly, correctly, and at a fair price. If you have a Raptor (or any Ford performance truck) and need honest, expert work in the Bay Area, this is the place to go. Highly recommend — I’ll definitely be back for future work. Thanks again, Jason!

Bought a truck from Devil Mountain Diesel that owner Mark said was fully overhauled. He promised email confirmation with the details — never sent it. Zero follow-through and total lack of professionalism on a major purchase. Called to follow up and got pure passive-aggressive Brokeback Mountain diva attitude from Mark: big sighs, “I’ll get to it when I have a chance,” zero help. Big tough guy acting like a miserable bitchy old woman. It was very weird the way he carried on. Pure petty queen energy — disappointing and unprofessional as hell. Would not recommend.

Worst manners on the phone. Submitted contact form on their website. Didn't hear from them for 5 days. Decided to call them. After 2 days of calling (because it just kept ringing and ringing) finally got someone on the phone but he had the worst attitude I've come across in a looooong time. Can't speak on their work but with that kind of reception, I won't get the chance to see for myself. Definitely spend your money elsewhere, with someone who will appreciate your business.

Mark and his team were great with installing some Banks gear on my 6.7 Cummins as well as installing a full Carli Backcountry set-up. Truck rides and looks awesome!

Jason and his team at Devil Mountain Diesel have done extensive work to fix up our 14-year old Sportsmobile "Classic" 4x4 2006 Ford E350 Van. This included: replacing front wheel disk pads, rotors, steering gear, ball joints, shocks, and brake pads. But their biggest job was to "bullet proof" the engine to take care of potential cooling problems that might crop in the future, and to fix or replace any items that they found where needed. Finally, they also adjusted the transfer case so that the 4x4 high manual stick shift worked properly. We have now taken out the Van on a few trips into 'The Wild' and are very happy with the excellent work they have done. It gives us confidence that we are not going to get stuck in some remote place because of preventable mechanical problems. Thx much to Devil Mountain Diesel!!!
