108 4 Pro 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 four; this will be the new arm weight to use
