Wiseco Chevrolet LS RED- LS 4.000in Stroke Flat Tops 4.130in Bore - Set of 8

If you're building a high-performance Chevrolet LS engine for serious racing, like drag or circle track, these Wiseco RED series pistons are a solid choice. They're forged from 2618 aluminum, which gives them the tensile strength needed for demanding applications and power adders. The RED designation stands for Race Engineered Design, meaning they're built with precision-machined features to give you a competitive edge.

Wiseco machines these pistons in the USA, and they've included some smart details to help with longevity and performance. The horizontal slot oiling in the pin bores keeps the wrist pins and connecting rod small ends well-lubricated, which is crucial for long service life. They also use dedicated forgings for an optimized, strutted design that balances strength and weight effectively. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also cutting down on skirt and cylinder wear. You also get premium rings included with each set, so you won't have to source those separately. An accumulator groove is built in to help maintain consistent ring seal and power delivery.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for specific LS engine builds and are a key component for anyone looking to push their engine's limits.
