The WISECO SK1141 Standard Bore Piston Kit is designed for specified Arctic Cat snowmobile applications, including select EXT 580, Pantera 580, and ZR 580 models from 1993 through 1998. This piston kit is sold per cylinder and includes a precision-matched piston, rings, and circlip. The kit also includes a wrist pin as part of the Pro-Lite series piston configuration.

WISECO pistons are forged from high-silicon, low-expansion aluminum to provide strength, reduced weight, heat transfer, and long service life. A diamond-turned finish produced on CNC-controlled turning centers is designed to provide a consistent finish with no size variation.

The WISECO SK1141 piston can be installed in cylinder bore compositions including cast iron, chrome, Nikasil, and boron composite, according to the applicable application requirements. WISECO’s piston range also includes oversize options for extending the service life of cast iron-lined cylinders, while replacement cylinder sleeves can support resleeving chrome, Nikasil, and boron composite cylinders for compatible oversize pistons.

Compatible applications include the 1993 Arctic Cat EXT 580 Z; 1994–1996 Arctic Cat ZR 580; 1996 Arctic Cat EXT 580 Deluxe EFI and EXT 580 EFI; 1997 Arctic Cat EXT 580 Deluxe EFI and EXT 580 EFI; 1998 Arctic Cat EXT 580 Deluxe EFI and Pantera 580.
