AWAG Custom Diesel Services, origin story:
FAMILY OWNED HORSEPOWER
12 years ago, we took our leap of faith towards keeping the future of old-school power alive and well. As the memories of mechanical Caterpillars, Big Cams, Red Tops, 60 series, and the infamous 12 valve Cummins fade away into the abyss, here at AWAG Custom Diesel Services, we're keeping our forefathers black smoke dreams alive.
We work on a wide range of class 8 heavy-duty models, machinery alike, and light-duty pickup trucks. We take pride in keeping the "true motors" of the 1960's up to the late 2000's running like new.
We aren't your standard parts changers. With over 100 years combined experience with old-school trucks, we strive make your truck like new again. This task comes at the behest of digging deeper into the issue, finding the problem, and fixing the issue for the long run. Our love and passion to see these trucks/motors running well into the next century keep our minds and hearts sharp. Passion and desire aren't dead here!!!!!
For us, our job isn't done until the customer is happy, safely on their way, and enjoying the drive.
