Last night in Evansville was awesome. It has been a very long off season for everyone with a lot of work to get ready. We could not be happier for our customers that had a great showing last night.
1st Jeremy Yeager- Trencher
1st Colin Ross- Triple Bypass
1st Grayson Shelton - Cutting Edge Pro
2nd Jeff Sapp - Blackjack
3rd Chance McGrath- Last chance.

With everything from finishing up the Blackjack tractor Tuesday for its maiden voyage to being on the dyno till Wednesday evening sorting things out on another, it has been a bit of a struggle. Seeing the results of last night for our customers makes it all worth it.
Congratulations, and thank you!

At Chaos Fabrication, updating our parts to meet the needs of our customers and the industry is something we take great pride in. The DT Rocker for the Chaos DT Engine was recently modified to make even better performance possible. From design to production and then to testing, all of the parts we make take a great deal of time and thoughtfulness to produce. The DT Rocker is not the only part that received an upgrade during the off season, so follow our page and keep checking back to see what we have been working on.
