• CNC machined with diamond-turned finish for perfect dimensional accuracy
• Optimized forging design provides superior heat transfer and extended service life
• Proven grain structure alignment for enhanced impact and fatigue resistance

Wiseco pistons are manufactured using an exclusive forging process that compresses the aluminum's molecular structure, creating a denser, stronger piston compared to cast alternatives. This forging process aligns the grain flow of the alloy, resulting in superior resistance to the extreme conditions of high-performance motorsport applications. Each Wiseco piston is precision-machined in their state-of-the-art computerized facility to ensure consistent quality and perfect fitment.

Important Notes:

• Standard bore piston - no cylinder modification required
• Only Wiseco replacement ring sets can be used on Wiseco pistons
• Complete 4-stroke piston kit includes all necessary components for installation
• Designed for racing and high-performance applications
