Wiseco Chevy SB RED Series Piston Set 4165in Bore 1125in Compression Height 0927in Pin - Set of 8

If you're building a performance Chevy Small Block engine, this Wiseco RED Series piston set is a solid choice. These pistons are forged from 2618 aluminum, a material known for its high tensile strength, making them well-suited for the demands of racing and applications with power adders like turbochargers or superchargers. The RED series stands for Race Engineered Design, meaning Wiseco has optimized these pistons specifically for competitive engine builds.

Wiseco machines these pistons in the USA, and they feature a horizontal slot oiling system in the pin bores. This design helps keep the wrist pin and the connecting rod's small end properly lubricated, which is crucial for extending the life of these high-stress components. The dedicated forgings allow for an engine-specific strutted design, balancing strength with a manageable weight. You'll also find an accumulator groove, which helps maintain consistent ring seal and power delivery. Plus, each set comes with premium rings, so you won't need to source those separately.

These pistons also include an ArmorGlide skirt coating. This coating works to reduce friction and noise from the piston skirt against the cylinder wall, which also helps to reduce wear on both the skirt and the cylinder itself. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
