Wiseco Chevy SB RED Series Piston Set 4165in Bore 1062in Compression Height 0927in Pin - Set of 8

If you're rebuilding the heart of your Chevrolet Small Block engine for serious performance, like drag racing or circle track, this Wiseco RED Series piston set is built to handle the demands. These aren't your average pistons; they're forged from 2618 aluminum, a material chosen for its high tensile strength, which is exactly what you need when you're pushing an engine hard, especially with power adders.

Wiseco's Race Engineered Design (RED) philosophy means these pistons are more than just strong. They feature horizontal slot oiling in the pin bores to keep the wrist pin and connecting rod small end well-lubricated, which is crucial for longevity under stress. The dedicated forgings allow for an engine-specific strutted design, balancing strength with a manageable weight. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also cutting down on wear to the piston skirt and cylinder wall. 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 hunt for compatible ones.

This set is designed for a 4.165-inch bore with a 1.062-inch compression height and a 0.927-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
