For 2008-to present Skidoo XP/XS/XM AND ;G4 QRS Driven Clutch/Secondary Clutch
 
Hi-Torque snowmobile QRS standard clutch rollers are up to 40% stronger, which translates into huge benefits as only 2 rollers are carrying the load as opposed to the traditional 3 rollers. Hi-Torque clutch rollers use a stainless steel thrust washer in combination with a small diameter raised roller face which greatly reduces roller side thrust friction and results in a very consistent engine RPM and a smoother acting clutch.
