Overview of Kimpex OEM-Type Piston Assembly - 82mm Bore - 09-778M

  • Dennis Kirk has high-quality, OEM-type piston assemblies to fit most popular snowmobiles
  • These pistons more closely match the original equipment in ring design, construction and weight than our other aftermarket pistons
  • Its not necessary to replace both pistons in a twin-cylinder engine if you need only one
  • All piston assemblies include rings(s), wrist pin and circlips
  • Bore size: 82mm/Standard


NOTE: Dennis Kirk recommends the following preliminary work to be performed by a qualified mechanic prior to installing new pistons. If the old piston has failed, determine the cause and remedy the problem before replacing. Air leaks and/or a lean fuel mixture are the two biggest causes of burned pistons. In cases where any part of the old piston is broken or burned through, the crankcase should be disassembled and throughly flushed of any debris.

NOTE: For sleeved, standard sized cylinders, chrome faced rings are recommended.
NOTE: Teflon coated

Our pistons, rings and kits are sold by application and bore size. Please note that STANDARD and OVERSIZES are not indicated. To get the correct part, you must know the standard bore size to make sure you are ordering either the standard or correct amount of oversize that you need. If you have any questions, please call Technical Service.

It works

February 6, 2010

Installed on 2003 Summit 800. Be advised that it does not look exactly like the OEM piston, but it works just as well, or better. Don't forget that the ring needs to be turned to a specific location on the piston otherwise it won't compress all the way; AND there is an arrow on the piston face that needs to point toward the front of the engine. I'd recommend buying a new needle bearing when replacing the piston.

I would recommend this item to a friend.
