Wiseco RED Series Chevrolet Small Block 4.135in Bore 1.550in CH -1.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components for performance applications. This RED Series piston set is built for Chevrolet Small Block engines and uses Race Engineered Design (RED) principles 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 and machined right here in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard. They feature horizontal slot oiling in the pin bores to ensure your wrist pins and small-end connections stay well-lubricated, which is key for long service life. The dedicated forgings allow for an optimized strutted design, meaning Wiseco engineers can maximize strength while keeping the weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also cutting down on skirt and cylinder wear. You also get a set of premium rings included, so you won't have to hunt for those separately. An accumulator groove is also built-in to help maintain consistent ring seal and power delivery.

This set includes eight pistons, designed for a 4.135-inch bore with a 1.550-inch compression height and a -1.00 CC volume in the piston dish. Please note that these pistons are not CARB approved and cannot be shipped to California.
