Our new 6-tooth driver replaces your stock 4-tooth invulute drives. It is designed to drive off the track clips instead of the lugs, which reduces track damage when using high HP engines they also reduce track rolling resistance which equals more speed using less power (not legal for stock class racing). Shaft not included.
NOTE YOU WILL NEED TO INCREASE YOUR REAR SPROCKET BY 5-6 TOOTH SIZE TO KEEP THE SAME GEAR RATIO*
*NOTE: ARCTIC CAT AND YAMAHA REQUIRE ALL TRACK CLIPS TO BE INSTALLED TO USE THESE.*
