Wiseco Chevy SB RED Series Piston Set 4165in Bore 1550in 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, designed to handle the demands of racing and power adder setups. These aren't your average pistons; they're crafted with Race Engineered Design (RED) principles to give you a real edge on the track.

Each piston in this set is forged and machined 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 the wrist pin and small-end of the connecting rod stay well-lubricated, helping to extend service life. The dedicated forgings allow for an optimized, engine-specific strutted design, meaning Wiseco engineers have maximized the strength-to-weight ratio for each piston. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall. An accumulator groove is included to help maintain consistent ring seal and power delivery.

This set includes premium rings, so you won't need to source them separately. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance racing and power adder applications.
