About US

Dmitri Millard, owner of No Zone Diesel, is a pioneer in the industry and has taken his hobby and love for the Duramax/Allison platform and turned it into a flourishing business! He is now one of the best known names in high-performance diesel transmissions, competition events, and dyno competitions.
Millard competed in the original Ultimate Callout Challenge in Salt Lake City, Utah back in 2016 but sat out the 2017 competition with his own truck, opting instead to lend his expertise to help a few other competitors during the event. Millard has competed in recent years at the UCC events in Indianapolis, Indiana with his single cab 2001 Chevrolet duramax known as “Overkill” and his regular cab 2003 Chevrolet 2500, affectionately nicknamed “Katrina”.
As a past diesel power challenge competition champion and veteran, Millard has continuously pushed the performance envelope of the Duramax engine platform. He has seen his share of elation and disappointment, both on dragstrips and on chassis dynos. He has recorded some of the quickest and fastest Duramax powered truck times, as well as, the highest Duramax dyno numbers at over 2,300 horsepower. He has also experienced blown tires, pieces of his engine scatter under the truck with catastrophic failure, and the resulting fireball that goes with it.
Undeterred, Dmitri relies on his extensive experience building Allison transmissions and continues to push performance limits with the help of his crew at No Zone Diesel.
