HD Secondary snowmobile QRS clutch rollers are up to 40% stronger than factory rollers, which translates into huge benefits as only 2 rollers are carrying the load as opposed to the traditional 3 rollers.
HD 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.
Primary clutch service life will be greatly increased after installing HD clutch rollers in the driven clutch, due to cooler running temperatures.
