I have only run ski-doos for one year, bought 02 7 x last spring, First time I ran the sled I knew there was something missing, so I order the thunder shift arms, what a difference, midrange and top end greatly improved,very easy to use, wide range of adjustment, only down fall so fare is the $$$$$$$$$$$ 320 with arms and adjustable pins, going to use on a 8 x Rev this season, has anyone tryied the 2mm rollers yet ? any help would be great.

Better sell the TS kit.. They will not work on ANY REV or new 03 Doo with a TRA III.. Sorry it's a smaller clutch.
