They are "The Best", I had three so called shops and one dealership look into my 1999 Dodge Dually Cummins to try and find why I was having a lack of power and suddenly worse mileage with no luck. I went to Diesel Pickup Specialist and in two days had more power than ever with better mileage. I won't let anyone other than them touch my truck ever since. These guys are great and make you feel like family. Hard to find anyone this honest at a fair price. I highly recommend you give them a try. - Larry B. (5 star review on Google)

Guys who know what they are doing! However, they are better at engine work than transmission work from our experience. I can recommend them for either though. - Jason M. (5 star review on Google)

I can always depend on Gary and his staff. They have got me out of an occasional breakdown. I would not trust anyone else with my diesel trucks. - Tera B. (5 star review on Google)

If I owned a diesel pickup, DPSI mechanics would be the ones I would go to for keeping my truck in tip top shape. I've seen what they can do...give 'em a try! - Darlene D. (5 star review on Facebook)

Always doing quality work for me! I always feel good about going on a long job after I pick my truck up from there. - Chris B. (5 star review on Facebook)
