He was announced as the driver for Hemelgarn Racing's car in the IndyCar Series in 2006 with new backing from NBA star Carmelo Anthony.

Chesson started the first 4 races of the season, the last being the Indianapolis 500, where he and teammate Jeff Bucknum tangled on the second lap and finished in the last two positions.

Chesson has numerous tattoos, including one of the 2006 Indianapolis 500 logo that he had applied in public at the Speedway during the final day of qualifying.

Since the demise of his deal with Hemelgarn, Chesson did not return to the Indycar Series until the end of the 2007 season when, in another Simmons/Abramson brokered deal, Chesson was announced as the second driver for Roth Racing alongside team owner Marty Roth with both cars sponsored by fashion label Dussault Apparel.

He made his 2007 debut at the final race of the season at Chicagoland Speedway and finished 19th after mechanical gremlins sidelined him for over 100 laps.
