Wiseco Chevrolet LS RED- LS 4.000in Stroke Flat Tops 4.040in 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 specifically designed for LS engines with a 4.040-inch bore and are built to handle a 4.000-inch stroke. The RED designation stands for Race Engineered Design, meaning Wiseco has put a lot of thought into making these pistons strong and precise for demanding applications like drag racing and circle track racing.

These pistons are forged from 2618 aluminum, which gives them the tensile strength needed for serious performance and when you're adding power adders like turbochargers or superchargers. Wiseco also machines them with features to give you an edge. You'll find horizontal slot oiling in the pin bores to keep the wrist pins well-lubricated, which is crucial for longevity. Each set comes with premium rings, so you don't have to hunt for those separately. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also cutting down on wear in the cylinder walls. An accumulator groove is included 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 manufactured in the USA.
