Mass Traction presents…
Demon Invitational Tulsa

Mass Traction Demon Invitational and Hemi Grudge Race at the 2018 NHRDA Oklahoma Diesel Nationals at Tulsa Raceway Park.

WHEN: MAY 19, 2018


The Mass Traction Demon Invitational & Hemi Grudge Race will allow Dodge Challenger SRT Demon & all Hemi owners to compete on a surface prepped to the extreme by Mass Traction – the company that provided the drag strip prep for the world record-breaking passes that gave the Demon its title as the quickest production vehicle and first production vehicle to achieve wheel lift. Mass Traction not only provided the drag strip prep but worked alongside SRT engineering throughout testing & media events and even built a drag strip launch pad inside of Pier 94 for the Dodge Challenger SRT Demon Reveal during the NY Auto Show!

Check out footage from the Mass Traction Demon Invitational New Orleans from our friends at Road Test TV!
