Easy replacement piston for the big bore kit. Comes with piston rings and circa clips. Use the circa clips provided. Athena does extensive R&D. The clips are deceiving but they are effective

Q: I'm looking to replace my stock pistons with these.?
2 years 8 months ago
My original piston is 50mm with a 50mm stroke at a 13.5:1 ratio. It is going to go into a 1972 Ski doo Blizzard 293 triple cylinder snowmobile. Will these fit the cylinders?

A: Usually pistons are model specific and unfortunately, since we do not deal with Snowmobiles, i have no specifications for the pistons for any models. It would be recommended to contact a reputable snowmobile dealership or a company that specializes in snowmobiles to make sure you obtain the correct pistons for this application.
