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.
