Wiseco Chevrolet LS RED- LS 4.000in Stroke Flat Tops 4.045in Bore - Set of 8

If you're building a high-performance Chevrolet LS engine, these Wiseco RED Series pistons are a solid choice. They're designed for a 4.000-inch stroke and a 4.045-inch bore, fitting popular domestic V8 platforms used in everything from drag racing to circle track. The RED designation stands for Race Engineered Design, meaning they're built with the strength and precision needed to handle serious performance and power adders.

These pistons are forged in the USA from 2618 aluminum, which gives them the tensile strength required for demanding applications. Wiseco also includes some smart features to help them last and perform. You'll find horizontal slot oiling in the pin bores to keep the wrist pins well-lubricated, and an accumulator groove that helps maintain consistent ring seal for better power delivery. The dedicated forgings allow for an optimized strutted design, maximizing strength while keeping weight down. Plus, they come with a premium ring set, so you don't have to source those separately.

To further reduce friction and noise, these pistons feature an ArmorGlide skirt coating. This not only helps them run quieter but also reduces wear on the piston skirts and cylinder walls, contributing to a longer service life for your engine build. When you're putting together a performance LS, these Wiseco pistons offer a well-built foundation.
