Construction & Design:

Each piston in this kit is crafted from high-quality forged aluminum alloy, providing an excellent strength-to-weight ratio essential for racing applications. The dome shape is carefully CNC-machined to achieve the +6.55cc volume, enhancing compression and flame travel within the combustion chamber.

Wiseco’s manufacturing process ensures tight tolerances and consistent quality, which translates to reliable performance and longevity even under extreme conditions. The pistons feature a durable surface finish to reduce friction and wear, while the pin bosses are reinforced to handle increased loads.
