Wiseco Chevrolet LS RED- LS 4.000in Stroke Flat Tops 4.080in Bore - Set of 8

If you're building a high-performance Chevrolet LS engine, Wiseco's RED Series forged pistons are a solid option. These pistons are specifically designed for LS engines with a 4.080-inch bore and a 4.000-inch stroke, offering the strength and precision needed for demanding applications like drag racing and circle track. They are engineered and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for handling the stresses of performance racing and boosted engines.

Wiseco's Race Engineered Design (RED) process results in pistons with optimized, strutted designs that maximize strength while keeping weight down. You'll find horizontal slot oiling in the pin bores, ensuring consistent lubrication for the wrist pins and connecting rod small ends, which is vital for long-term durability. Each set also comes with premium rings, so you don't have to source them separately. An accumulator groove is included to help maintain a consistent ring seal, contributing to reliable power delivery.

Additionally, these pistons feature an ArmorGlide skirt coating. This advanced coating helps reduce friction and noise during operation, while also minimizing wear on the piston skirts and cylinder walls. This combination of robust construction and thoughtful features makes the Wiseco RED Series pistons a well-built choice for serious LS engine builds.
