Overview of Parts Unlimited OEM-Type Piston Assembly - 67.72mm Bore - 09-704

  • 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
  • It's not necessary to replace both pistons in a twin-cylinder engine if you need only one
  • All piston assemblies include ring(s), wrist pin and circlips


  • Bore Size: 67.72mm/Standard
    Replacement Ring Set: 13527R
    Replacement Wrist Pin: S511
    Replacement Circlips: 14670

    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 thoroughly flushed of any debris.
    NOTE: This must be used without thrust washers (single ring Piston)

NOTE: Our ring design does not match OEM for the following models:
Polaris Cobra 78-79
Polaris Electra 74-77
Polaris Galaxy 80-81
The replacement rings will only fit our piston

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.

Great Value!!
I looked everywhere for these pistons and could not find them new anywhere for this price!!! I stumbled upon this site and was very impressed with price quality and turn around time. I will mention this site to everyone I know and I will definitely be purchasing through this Dennis Kirk again!
