Our Mission

There’s a reason you invested in a diesel truck - whether it’s torque, towing ability, or increase in fuel mileage for your long hauls. You’re towing loaded trailers up Idaho’s steep grades, dirt roads and interstates. It doesn’t matter if you have a new diesel or if you’re getting the most out of your trusty high mileage truck, it has to perform. With over 14 years of experience and 9,000 diesels repaired, if you've got a problem, chances are we’ve seen it and solved it.

What Our Customers Say About Us

Jean Murphy

No problems working on a 2007 Chevy Diesel. Didn't suggest I buy a new truck as others have.Very good at explaining procedures for repairs. Helpful with questions.

Justin Brown

When my 2008 F250 went into limp mode and I called Gem State Diesel they immediately instilled confidence with their detailed knowledge and wealth of experience. They knew the main issues with my truck’s 6.4L and confirmed the problem during diagnosis. I am not a gear head so appreciated their willingness to talk through the repair options, value and longevity of the options, and additional maintenance going forward. These repairs are not cheap but I have confidence it was done professionally, correctly, and have a 2 year warranty for peace of mind.

Joshua L. Darrow

I was having some issues with my Chevy Duramax. I wasn’t sure how to diagnose the problem. I called Joe at Gem State diesel & Turbo Repair. Joe spent a lot of time with me on the phone trying to help diagnose the problem. He listened intently to my concerns and offered multiple options for a possible solution. He was able to get me in right away. Had the truck diagnosed, found a solution to the problem, and had it back to me within 24 hours. I would highly recommend them as they are honest, affordable, highly experienced, and have unrivaled customer service. Thank you again Joe! ~ Josh

Howard Hooper

The Gem State team thoroughly went through my 2003 Chevy Duramax bringing my truck back to a performance level where I can have confidence in its performance when I'm in the back country or driving the ALCAN. Joe and team were great at communicating with me as we considered the preventative items or if deferring made sense. If you have a diesel that that you want to keep for awhile, I highly recommend the Gem State team.

Gem State does a good job on getting all my maintenance items worked in. They stand behind their work and quickly resolved any issues I had. The price of work is provided up front. They are not the cheapest around, but you truly get what you pay for and that is well worth it.
