When ordering use this guide to help you pick options:

Choose a year – let us know what year your sled is so we can make sure all the clutch components, bolt, puller, etc. are correct

Choose make – what is the make? This also helps us to make sure you are getting the right components

Enter your model – tell us what model you have, this assures you are getting the right offset and taper any extra info helps like (2 stroke or 4 stroke)

Choose a spider – pick what spider you want screw on or quick change. If you are getting this clutch for a trail sled we recommend you get the screw on style, the quick change is more for the drag racer. Quick change is not reccomended for trail use, Ski-Doo or Yamaha Vipers. 

Choose a taper – if you know what taper your crank has choose that taper if not try and look it up or call a dealer

Choose a diameter – choose your desired diameter keep in mind anything over 8-1/2 diameter is considered HEAVY DUTY and the price is increased.

Choose a pin kit – you will need to pick one of the pin kits listed for the style of weights you are going to use.
