Wiseco Chevy SB RED Series Piston Set 4125in Bore 1215in Compression Height 0927in Pin - Set of 8

Wiseco is well-known for making strong, reliable internal engine components for performance applications. This RED Series piston set is built for Chevy Small Block engines and uses their Race Engineered Design (RED) philosophy to give you the strength and precision needed for demanding builds. Whether you're hitting the drag strip or the circle track, these pistons are a solid foundation for serious power.

These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard, especially with power adders like turbos or superchargers. Wiseco machines these pistons with specific features to maximize strength while keeping weight down, using dedicated forgings for each engine application. You'll find horizontal slot oiling in the pin bores to ensure the wrist pin and small-end of the connecting rod stay well-lubricated, which is key for long service life under high stress. Plus, each set comes complete with premium rings, so you won't need to source those separately.

An accumulator groove is included to help maintain consistent ring seal, which means better compression and more power. The skirt of each piston also features an ArmorGlide coating. This coating helps reduce friction and noise during operation, and it also cuts down on wear to both the piston skirt and the cylinder wall. This attention to detail helps ensure your engine build performs well and lasts.
