No.you need the specific length and stroke,then each bike has it's own bushings and mounts.Saying that 165mm and 1.5" stroke is one of the most common shock sizes in the world,so all big manufacturers will do one,and bushing kits should be available.The Fox float fits a Riftzone,and improves the handling no end,I know,I sold my 1998 to my mate,and he replaced the Shockworks with a Fox.A good budget option is reckoned to be a Stratos TR1 at £110 approx.
