Dorr Wins on Saturday: 2015 Super Stock Truck Class Champion

Gets fitted for another World Championship Ring

DORR Wins on Saturday: Super Stock Truck Class Champion and World Champion

Mitch Dorr headed to Crandon for the final weekend of racing of the Sportsman Off-Road Series supported by MORR with two goals in mind. The first was to win the Super Stock Truck Championship and the other was to win another World Championship ring. The second-generation racer had some very tough competition, but was able to accomplish both goals halfway through the Labor Day Weekend event.

The weather for the Labor Day Weekend was unseasonably warm and the racing could be described in similar fashion. Twenty Super Stock Truck competitors were lined up door to door for one incredible land rush start. When the green flag was dropped the field made the 2000-foot charge into Potawatomi Turn One. Then as pack headed for the Barn Turn, Matt Siorek went into a violent barrel roll, somehow Siorek walked away from the incident, as the safety equipment did its job, but the race truck might seen its final time on the track.
The restart saw the field line up in row of two for a rolling start, this time the start went off with any issues. Quickly Mitch Dorr had the #897 Auto Trans Design Hi-Rev Graphics Super Stock Truck in the lead with Nick Byng attempting to keep pace with the white and black Ford F-150. Byng did his best to challenge Dorr for the top spot, but it just didn’t have what it would take to catch the leader. At the finish, Mitch Dorr would take the win and clinch the 2015 Super Stock Truck Championship for the second year in a row. The win would also give Dorr his third World Championship ring of his career.
Mitch and the team only celebrated slightly as the truck needed to be prepped for Sunday’s finale.
The final race of the season saw Dorr get the holeshot and lead the field through Turn One. Then on lap 2, while leading the race, a connecting rod punched a large hole in the engine block ending the day for the newly crowned Class and World Champion.

“Our goal this year was to back up our season long performance from a year ago,” commented Mitch Dorr. “I pretty sure we did that. The points difference between and second place looks like we had an easy time this year, but every race was a hard fought battle. We say it all the time, but it’s really true, more than half the class has a legitimate shot at the win every time out. You know I can’t thank my friends and family enough for all the support and all the late nights back at the shop and at the track. I have to thank Charlie and Mike at Auto Trans Design for building an incredible transmission and they have always been there to make sure our truck performs it best. Of course I can’t thank my mom and dad enough for the support, the hard work they have always put in, and always reminding me nothing comes easy and with effort comes rewards.”
Mitch would also like to thank his sponsors:
Automatic Transmission Design – K & N Filters – BFGoodrich Tires
High Rev Graphics – AMSOIL.

Keegan Kincaid Shatters Leduc’s Pro 4 Win Streak with ATD Turbo 400

Leduc had 13 straight wins going into the last TORC Pro 4 race of the season at Crandon.

Many said it couldn’t be done – that an automatic couldn’t dominate the manual transmissions in the Pro 4 class. The growing trend in Pro 4 short course off-road racing has been manual transmissions. The theory is that you can achieve better gear ratio splits and make the car faster and more nimble – but we know differently.

ATD has been successful for many years in Pro 4 with a properly designed Turbo 400 transmission package. In fact, testing an ATD automatic versus a manual transmission yielded faster, more consistent lap times. Some drivers have a different style and want to grab gears. That’s fine, we just know how to beat them.

And so does Keegan Kincaid.

That’s exactly what he did in Sunday’s Pro 4 race at Crandon. Piloting Mike Jenkins’s Traxxas Pro 4 to the top step of the box uncontested. Keegan had shown speed all weekend but ran into some mechanical difficulties while leading Saturday’s race. From the drop of the green flag on Sunday, Keegan pulled the holeshot and never looked back.

Keegan crushed the competition, finishing the race with only three remaining tires.

The winning combination:

  • ATD Prepped Turbo 400 for Short Course,
  • Reid Racing Super Hydra 400 Aftermarket Case,
  • Ultra Close Ratio Turbo 400 Gearset,
  • A Torque Converter.

The most commonly overlooked piece of the Pro 4 package is the torque converter. By choosing a clutch over a torque converter, you lose a performance edge. A properly designed torque converter is absolutely critical to winning races, and ATD can get you there.
