Need pistons for a 670 - where to get them, which ones to get?

[deaner]

Hey guys. My brother blew up his 99 summit 670. We pulled her apart and the PTO side piston lost a skirt. Luckily, everything else looks good. Just wondering what pistons you guys would recommend putting in. Should a guy just go OEM? Or are aftermarket ones going to be as reliable? Also, any idea where to get a good deal on this stuff. I need pistons (with all the extras, pins, bearings, etc) and gaskets for the entire motor.

Unfortunately, I've been through this a couple of times in the past 2 seasons with my 670. Pistons from Ski Doo are pretty spendy nowadays, I think in the $130 apiece range if I remember right. The guy I got my parts from ordered mine from WPS both times. They ran about $85 for kit that had the .50mm over piston, rings, wrist pin, and circlips. You would have to find a dealer to order them from WPS for you though.

Or you could order them from Dennis Kirk, looks like the kit runs about $55.

You should be able to find the bearings and gaskets and stuff on there too I would imagine.

I would use the factory Doo piston---They are now coated. They are double what they were about 5 years ago--But everything is more--especially when they go out of production.

This will take you right to the microfiche and pricing--You can order them on line and they ship right to you. They are quicker than having any of the 5 dealers closer to me order the parts.

PS--Make sure you get the case cleaned out real well.

Thanks guys. What do you think of Wisecos? You are fairly inexpensive arent they??

Use the coated SPI's, WPS sells these.
