Wiseco Chevrolet LS -4cc Flat Top 1.294 X 4.015 - Set of 8

If you're building a performance Chevrolet LS engine, Wiseco's RED Series forged pistons are a solid choice. These pistons are specifically designed for the demands of racing and high-power applications, offering the strength and durability needed to handle serious performance. The -4cc flat top dish is designed to work with specific LS engine configurations, helping you achieve your desired compression ratio.

Wiseco crafts these pistons from 2618 aluminum, a material known for its tensile strength, which is crucial for engines that see high stress from racing or power adders. They feature horizontal slot oiling in the pin bores to ensure the wrist pin and connecting rod small end stay well-lubricated, a detail that contributes to a longer service life. The dedicated forgings allow for a strutted design that maximizes strength while keeping weight down, a key factor in overall engine performance. Plus, each set comes complete with premium rings, so you won't need to source those separately.

For added performance and longevity, these pistons include an accumulator groove to help maintain consistent ring seal and power output. They also feature an ArmorGlide skirt coating, which works to reduce friction and noise during operation, while also minimizing wear on the piston skirt and cylinder wall. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
