Wiseco RED Series Chevy Small Block 350 4.000in Bore 1.550in CH 3.00 CC Piston Set

This is a set of eight Wiseco RED Series pistons designed for Chevrolet Small Block 350 engines with a 4.000-inch bore. The RED series, which stands for Race Engineered Design, uses 2618 aluminum forgings. This material is chosen for its tensile strength, making these pistons well-suited for high-performance applications and engines that use power adders like turbochargers or superchargers.

Each piston features horizontal slot oiling in the pin bores to ensure the wrist pin and connecting rod small end stay properly lubricated, which is important for longevity. The dedicated forgings allow for an optimized, engine-specific strutted design that balances strength with weight. Wiseco also includes an ArmorGlide skirt coating to help reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall. An accumulator groove is incorporated to help maintain consistent ring seal and power delivery.

This set comes complete with premium rings, so you won't need to source them separately. Please note that these pistons are not CARB approved and cannot be shipped to California.
