The WISECO SK1238 Overbore Piston Kit is designed for top-end rebuild applications. Wiseco pistons are forged from high-silicon, low-expansion aluminum to provide strength, reduced weight, improved heat transfer, and long service life. The kit includes a precision-matched piston, rings, and circlip for one cylinder.

Each piston features a diamond-turned finish produced on CNC computer-controlled turning centers for a consistent finish and size. Wiseco pistons can be installed in cylinder bores made from cast iron, chrome, nikasil, and boron composite materials. The available range of oversize pistons can also help extend the service life of cast iron-lined cylinders.

The WISECO SK1238 Overbore Piston Kit is manufactured for powersports performance and recreational applications. Replacement cylinder sleeves allow chrome, nikasil, and boron composite cylinders to be resleeved for use with Wiseco oversize pistons.
