bobby z, i read on associated's site that the suggested gearing won't fit unless you use the kimbrow offset ride height spacers, they forget to mention that in their manuals. for gearing you have to find the roll out to get proper gearing, if you are running a monster stock you can gear it around a 40-42mm roll out, green macine 3's are around 44-47, i gear 10 turns around a 35-37, 12's closer to 40.
