The WISECO SK1261 Standard Bore Piston Kit is designed for the listed Arctic Cat applications and provides precision-matched components for a top-end rebuild. This piston kit is sold per cylinder and includes a precision-matched piston, rings, and circlip. The Pro-Lite series also includes a wrist pin.

WISECO pistons are forged from high-silicon, low-expansion aluminum for strength, reduced weight, improved heat transfer, and extended service life. A diamond-turned finish produced by CNC-controlled turning centers is intended to provide a consistent finish with minimal size variation.

The WISECO SK1261 piston can be installed in cylinder bore compositions including cast iron, chrome, Nikasil, and boron composite. WISECO also offers oversize pistons for extending the life of cast iron-lined cylinders, while replacement cylinder sleeves allow chrome, Nikasil, and boron composite cylinders to be resleeved for WISECO oversizes.
