Wiseco Chevrolet LS RED- LS 4.000in Stroke Flat Tops 4.165in Bore - Set of 8

If you're building a high-performance Chevrolet LS engine for serious racing, like drag or circle track, you need pistons that can handle the stress. Wiseco's RED series pistons are built for exactly that. They use a Race Engineered Design (RED) process to give you the strength and durability needed for demanding applications, with precision features that help you get a competitive edge.

These pistons are forged and machined in the USA from 2618 aluminum, a material known for its tensile strength, which is crucial when you're pushing an engine hard, especially with power adders. They feature horizontal slot oiling in the pin bores to keep the wrist pins and connecting rod small ends well-lubricated, which is key for a long service life. The dedicated forgings allow for an optimized, strutted design specific to the LS engine, maximizing strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also cutting down on skirt and cylinder wear. You also get accumulator grooves to help maintain consistent ring seal and power, and each set comes complete with premium rings, so you don't have to source them separately.

Keep in mind these pistons are not CARB approved and cannot be shipped to California. They are designed for engines that will be used in racing and performance applications.
