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.
