Wiseco Chevrolet LS RED- LS 4.000in Stroke Flat Tops 4.145in 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 designed to handle the demands of boosted or naturally aspirated powerplants, offering the strength and precision you need to get the most out of your build. The RED designation stands for Race Engineered Design, meaning these pistons are built from the ground up for competitive performance.

Crafted from 2618 aluminum in the USA, these pistons are forged for exceptional tensile strength, crucial for engines that see high RPMs and significant stress. They feature horizontal slot oiling in the pin bores to ensure the wrist pins and connecting rod small ends stay well-lubricated, which is key for long-term durability. Wiseco uses dedicated forgings for each specific LS engine application, allowing them to create a strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, leading to less wear on the piston skirts and cylinder walls.

This set includes premium rings, so you won't need to source them separately. An accumulator groove is also incorporated to help maintain consistent ring seal and consistent power delivery. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
