Wiseco RED Series Chevy LS 4.085in Bore 1.105in CH -20.00 CC Piston Set

If you're building a high-performance Chevy LS engine for racing, whether it's for drag strips or circle tracks, you need pistons that can handle the stress. The Wiseco RED Series pistons are designed specifically for these demanding applications, offering a strong and durable foundation for your build.

These pistons are forged and machined in the USA from 2618 aluminum, chosen for its high tensile strength, which is essential when you're pushing an engine hard or adding forced induction. Wiseco's Race Engineered Design (RED) process means these pistons are optimized for strength and weight, using dedicated forgings with a strutted design to maximize performance. They feature horizontal slot oiling in the pin bores to ensure the wrist pin and connecting rod small end stay well-lubricated, which is crucial for longevity. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also cutting down on skirt and cylinder wear. Each set comes complete with premium rings, so you don't have to hunt for compatible ones.

An accumulator groove is included to help maintain consistent ring seal and power delivery under extreme conditions. Keep in mind these pistons are not CARB approved and cannot be shipped to California. For a serious LS build, these Wiseco RED Series pistons offer a well-built option designed for competitive performance.
