Comet 108 4-Pro Tapered Clutch


  • Comet 108 4-Pro clutches accept OEM starter rings
  • Added fourth load-bearing member increases roller and button life
  • These race clutches are for high-performance applications ONLY
  • Uses four clutch weights to greatly enhance tuneability
  • Arms can be used in sets of two to better zero-in on desired weight
  • Uses same springs as 102-C and 108-EXP clutches
  • Captivated tower allows shouldered cover bolts to virtually eliminate tower spreading
  • Features a bushing in the movable face
  • To determine arm, add weight of three arms used in 108-EXP, add 14%, then divide by 4; this will be the new arm weight to use
  • For calibrations contact a high performance specialist

Product Note: Includes Ski-Doo Gear Bosses.
