The WISECO SK1257 Standard Bore Piston Kit is designed for a top-end rebuild application. This kit includes a precision-matched piston, rings, and circlip. The Pro-Lite series piston also includes a wrist pin. Piston kits are sold per cylinder, providing components for one cylinder.

WISECO forged pistons are manufactured 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 supports a consistent, precise finish.

The WISECO SK1257 piston can be installed in cylinder bore compositions including cast iron, chrome, Nikasil, and boron composite. WISECO also offers oversize piston options 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 oversize pistons.
