Wiseco RED Series Chevy LS 4.085in Bore 1.294in CH -15.00 CC Piston Set

When you're building a high-performance Chevy LS engine, you need parts that can handle the stress of racing and power adders. This piston set from Wiseco's RED Series is designed specifically for that purpose. You get a complete set of eight pistons, forged from 2618 aluminum for the tensile strength required in demanding applications. Each set also includes premium rings, so you won't need to source those separately.

Wiseco's Race Engineered Design (RED) philosophy means these pistons are more than just strong. They feature horizontal slot oiling in the pin bores to ensure your wrist pins and connecting rod small ends stay well-lubricated, which is crucial for long service life. The dedicated forgings allow for an optimized, engine-specific strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls. An accumulator groove is also included to help maintain consistent ring seal and power delivery.

These pistons are engineered, forged, and machined right here in the USA. Keep in mind that this specific part number is not CARB approved and cannot be shipped to California. For serious LS builds, this set offers a well-built foundation.
