The WISECO 2471M08500 Standard Bore Piston Kit is designed for specified Polaris 850 snowmobile applications. This piston kit is sold per cylinder and includes a precision-matched piston, rings, and circlip. The Pro-Lite Series piston also includes a wrist pin.
WISECO pistons are forged from high-silicon, low-expansion aluminum for strength, reduced weight, improved heat transfer, and long service life. A diamond-turned finish produced on CNC-controlled turning centers is intended to provide a consistent finish without size variation.
The WISECO 2471M08500 piston can be installed in cylinder bores composed of cast iron, chrome, Nikasil, and boron composite materials. WISECO also offers oversize piston options for cast iron-lined cylinders, while replacement sleeves can allow chrome, Nikasil, and boron composite cylinders to be resleeved for WISECO oversize pistons.
