VINTON, Iowa – IMCA Sunoco Stock Car drivers see a rule already familiar to Modified racers go into effect beginning next year.
IMCA aftermarket transmissions with an aluminum case and internal clutch will be legal for use at sanctioned Stock Car events beginning Jan. 1, 2021.
The current approved aftermarket transmission list includes:
* Falcon p/n 60100;
* Bert p/n LMZ and Generation II models 1300 and 1400;
* Brinn p/n 70001 and Brinn Predator p/n 70600 (new addition);
* Mitchell Machine Bullet Internal Clutch;
* and RaceGator p/n 140002.
These are aluminum case transmissions and the transmission rule specifically states No ball-spline transmissions. The use of any other aftermarket transmission, including magnesium case or ball-spline is not legal. Transmissions may not have any type of coatings or paint.
“The Stock Car division has been one of our most popular and talked about divisions and we continue to see it expand with new sanctions where the Modified division is already established,” explained IMCA President Brett Root. “As supply and demand issues continue to present themselves, we feel the time is right to make this decision and corresponding announcement.”
