About Comet 108 4-Pro Clutch

Comet 108 4-Pro Clutch

  • Comet 108 4-Pro clutches now accept OEM starter rings
  • Added fourth load-bearing member increases roller and button life
  • These race clutches are for high-performance applications ONLY
  • Clutch uses four clutch weights to greatly enhance tuneability
  • To determine arm, add weight of three arms used in 108-EXP, add 14%, then divide by four; this will be the new arm weight to use
  • 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
  • Each features a new bushing in the movable face and redesigned fixed face for increased durability
  • IMPORTANT NOTE: These clutches are for racing use only. For calibration, contact a high performance specialist or Comet Industries.
