Other Key DynoMax Finishers Include Levi Shirley, Jason Scherer & Tom Wayes; Justin Hall Secures Second Place Finish in 4500 Race

Monroe, MI, July 23, 2015 – DynoMax driver Loren Healy won first place at the

ULTRA4 4 Wheel Parts Glen Helen Grand Prix. On a tight, windy course, Healy

maneuvered through a field of broken rigs to secure the win. DynoMax also had multiple

qualifiers for the event including Jason Scherer, Tom Wayes, Levi Shirley, Wayland

Campbell and Bailey Campbell. In the 4500 Modified series race, Justin Hall picked up a

second-place finish.

“Members of Team DynoMax had some exciting races at Glen Helen,” said Chris

Gauss, director of performance products, Tenneco. “Congrats to Loren for keeping the

winning streak alive, and to Justin Hall, he’s a true ‘every man’ racer who enjoys working

on his rig in his driveway – both drivers are great competitors and we’re excited to see how

they fare as the season continues.”

In the 4400 race, many drivers opted for 37-inch tires, as the course did not feature

many rocks. Scherer, Healy and Campbell battled through a portion of the race, with Healy

eventually pulling away. Healy built a large lead after Wayes encountered mechanical

issues, Scherer lost a belt that took out his engine and Shirley left the course with a

transmission failure. Thanks to that lead, when Healy rolled over and landed back on his

wheels, he was able to keep running, taking the win by less than three seconds.

Shannon and Wayland Campbell made some calculated race-day decisions

following Shannon’s time penalties. Wayland was able to drive Shannon’s rig for the race

because he qualified higher. Wayland’s race was cut short when Shannon’s rig lost 4WD,

but he still secured a sixth place finish due to his completed number of laps. Bailey

Campbell also finished the race in eighth place.

Fifty drivers competed in the 4400 Series, including those on Team DynoMax.
