Wiseco Chevy SB RED Series Piston Set 4155in Bore 1215in Compression Height 0927in Pin - Set of 8

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of performance racing and power adder applications. The Race Engineered Design (RED) series offers a strong foundation for engines used in everything from drag racing to circle track racing, providing the durability and precision needed to compete.

Each piston features horizontal slot oiling in the pin bores to ensure consistent lubrication for the wrist pin and small end of the connecting rod, which is crucial for long service life under high stress. Dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. The ArmorGlide skirt coating further reduces friction and noise, while also minimizing wear on both the piston skirt and cylinder wall. This set includes premium rings, so you won't need to source them separately, and an accumulator groove helps maintain consistent ring seal and power delivery.

This set is designed for Chevrolet Small Block engines with a 4.155 inch bore, a 1.215 inch compression height, and a 0.927 inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
