Wiseco Chevy SB RED Series Piston Set 4060in Bore 1550in Compression Height 0927in Pin - Set of 8

Wiseco is well-known for making strong, reliable engine components for racers and performance enthusiasts. This RED Series piston set is built for demanding Chevy Small Block applications where strength and precision are critical. These aren't your average pistons; they're forged from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for high-RPM use and boosted or naturally aspirated performance engines.

The Race Engineered Design (RED) behind these pistons means they're not just strong, but also smart. They feature horizontal slot oiling in the wrist pin bores to ensure the wrist pin and connecting rod small end stay well-lubricated, which is key for longevity in a performance engine. Wiseco also uses dedicated forgings that allow for an optimized, engine-specific strutted design, balancing strength with a manageable weight. To further reduce friction and wear, these pistons come with an ArmorGlide skirt coating, which also helps quiet down operation. Each set includes premium rings, so you won't need to hunt for those separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

This set is designed for a 4.060 inch bore with a 1.550 inch compression height and a 0.927 inch pin diameter. It's important to note that these pistons are not CARB approved and cannot be shipped to California. They are a set of 8 pistons, ready to be installed in your performance build.
