Variator Rollers 15x12. Set of 6.
Rollers are what makes your CVT Transmission shift. These 'shifters' come in different weights. Most likely the OEM rollers in your ATV's transmission weigh between 7.5 and 8 grams. These heavy, general purpose rollers work fine if performance is not an issue. On the other hand if you want more performance from your ATV you will need to change the OEM rollers to the lighter ones.
