Wiseco Chevrolet LS RED- LS 4.000in Stroke Flat Tops 4.135in Bore - Set of 8

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of high-performance Chevrolet LS engines. The RED designation stands for Race Engineered Design, meaning each piston is precisely machined to offer both the strength needed for racing and the durability for long service life, especially when using power adders. This set is designed for a 4.135-inch bore and a 4.000-inch stroke, featuring flat-top designs that are crucial for specific engine builds.

Wiseco incorporates several thoughtful features to ensure optimal performance and longevity. Horizontal slot oiling in the pin bores keeps the wrist pin and connecting rod small end well-lubricated, which is vital under high stress. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. Additionally, an accumulator groove helps maintain consistent ring seal, ensuring you get the most power out of every combustion cycle. The included ArmorGlide skirt coating not only reduces friction and noise but also minimizes wear on the piston skirt and cylinder wall.

This set comes complete with premium rings, so you won't need to source them separately. These pistons are engineered, forged, and machined in the USA, reflecting a commitment to quality and performance. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance applications where strength and precision are paramount.
