- Either original equipment in the Comet drive clutches or a popular replacement for trail riding or racing
- 102-C, 108-C and 108-EXP clutches all use the same basic cam arm
- 108 4-PRO clutches use FOUR cam arms. (To find the required cam arm weight, add the weight of three cam arms used in a 108-EXP or other three-post clutch, add 14%, then divide by FOUR. This will give you the required new cam arm weight.)
- When ordering cam arms for a 108 4-PRO clutch, you must order FOUR cam arms to get the correct weight
- Comet arm weight objective is within .75 grams of that listed. Certified weights would be significantly more expensive. The variance may occasionally exceed 2 grams and is a result of greater or lesser arm density.
