Our new REVISED 5-tooth track drivers replace your stock 4-tooth involute drives. It is designed to drive off the track clips instead of the lugs, which reduces track damage when using high horsepower engines. They also reduce track rolling resistance which equals more speed using less power (not legal for stock class racing.) Drivers will fit stock drive shaft.
*NOTE YOU WILL NEED TO INCREASE YOUR REAR SPROCKET BY 5-6 TOOTH SIZE TO KEEP THE SAME GEAR RATIO*
