Wiseco Chevy SB RED Series Piston Set 4155in Bore 1550in Compression Height 0927in Pin - Set of 8

If you're building a high-performance Chevrolet Small Block engine for racing, like drag or circle track, you need pistons that can handle the stress. This Wiseco RED Series piston set is built for those demanding applications. They are forged from 2618 aluminum, a material chosen for its high tensile strength, which is essential when you're pushing an engine hard or adding power adders.

Wiseco's Race Engineered Design (RED) process means these pistons are specifically optimized for their intended engines, using dedicated forgings to achieve a strong yet lightweight design. You'll find horizontal slot oiling in the pin bores, which helps keep the wrist pin and connecting rod small end well-lubricated, a critical factor for longevity in a performance build. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also cutting down on wear to the piston skirt and cylinder walls. Each set comes complete with premium rings, so you don't have to hunt for compatible ones separately, and an accumulator groove helps ensure consistent ring seal for maximum power.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a serious performance build, this set offers a well-built foundation.
