Wiseco Chevrolet LS -4cc Flat Top 1.294 X 4.140 - 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 a strong foundation for your build. They feature a flat top design with a -4cc dish and a 4.140-inch bore, making them suitable for a wide range of LS engine configurations.

Crafted in the USA from 2618 aluminum, these pistons are built for tensile strength and durability. Wiseco engineers them with a dedicated forging process that optimizes the strutted design for maximum strength while keeping weight down. You'll also find horizontal slot oiling in the pin bores to ensure proper wrist pin and small-end lubrication, which is crucial for a long service life in a high-performance engine. The ArmorGlide skirt coating further reduces friction and noise, while also minimizing wear on the piston skirts and cylinder walls. Each set comes complete with premium rings, so you won't need to source those separately.

An accumulator groove is included to help maintain consistent ring seal and power output. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious LS engine builds, these Wiseco pistons offer a well-built and performance-oriented solution.
