Frequently bought together:


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.
