Wiseco Chevy SB RED Series Piston Set 4155in Bore 1000in Compression Height 0927in Pin - Set of 8

Wiseco is well-known for its high-performance forged pistons, and their RED Series is built for serious racing applications. If you're rebuilding a Chevrolet Small Block engine for drag racing, circle track, or any other demanding performance use, these pistons are designed to give you a competitive edge. They utilize Race Engineered Design (RED) to offer the strength and durability you need, combined with precision-machined features.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for performance racing and applications with power adders. To ensure optimal lubrication and extend service life, they feature horizontal slot oiling in the pin bores, which keeps the wrist pin and small-end of the connecting rod properly lubricated. The dedicated forgings allow for an engine-specific, strutted design that maximizes the strength-to-weight ratio. Additionally, each set comes with premium rings, so you won't need to source those separately, and an accumulator groove is included to help maintain consistent ring seal and power output.

This set includes eight pistons, designed for a 4.155-inch bore with a 1.000-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.
