Description

The Wiseco legacy is rooted in 2-stroke piston manufacturing and performance, dating back to 1941--over 80 years ago. Today, their pistons are the result of decades of experience, incorporating the latest in 2-stroke piston manufacturing and design to deliver the performance Wiseco built its name on.

Wiseco Marine Forged Series 2-stroke piston kits are engineered, designed, and machined for each specific engine. The improved tensile strength of the forged aluminum material optimizes strength and service life, while these dedicated forgings, along with additional lightening operations, allow for optimized strength-to-weight ratio. Each Wiseco forged piston kit includes high-quality piston ring(s), wrist pin(s), and circlips. Select the kit with the proper specs for your marine engine.
