Wiseco RED Series Chevy Small Block 400 4.125in Bore 1.125in CH -21.00 CC Piston Set

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 400 engines, designed to handle the demands of racing and power adder setups. They utilize Race Engineered Design (RED) to give you a competitive edge with precision-machined features.

These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for performance racing and when adding forced induction or nitrous. Each set includes premium rings, so you don't have to source them separately. The pistons feature horizontal slot oiling in the pin bores to keep the wrist pins and connecting rod small ends properly lubricated, which is key for a long service life. Dedicated forgings allow for an optimized, engine-specific strutted design that maximizes strength while keeping weight down. An accumulator groove is also included to help maintain consistent ring seal and power delivery.

The ArmorGlide skirt coating on these pistons works to reduce operating friction and noise. This coating also helps to minimize skirt and cylinder wall wear, contributing to the longevity of your engine build. Please note that these pistons are not CARB approved and cannot be shipped to California.
