Wiseco Chevy SB RED Series Piston Set 4000in Bore 1425in 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 utilizes their Race Engineered Design (RED) philosophy to offer the strength and durability needed for demanding performance builds. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making it suitable for racing and engines with power adders.

Each piston in this set features horizontal slot oiling in the pin bores. This design helps keep the wrist pin and small-end of the connecting rod properly lubricated, which is crucial for a long service life in a high-performance engine. The dedicated forgings allow for an engine-specific, strutted design that maximizes strength while keeping weight down. To further reduce friction and wear, these pistons come with an ArmorGlide skirt coating, which also helps quiet down operation. 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. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
