Wiseco Chevy SB RED Series Piston Set 4010in Bore 1425in Compression Height 0927in Pin - Set of 8

Starting with pistons forged from 2618 aluminum, the Wiseco RED Series is built for the demands of performance racing and power adder applications. These pistons are engineered and machined in the USA, ensuring they have the tensile strength needed to handle the stress of high-performance engines, whether you're building for drag racing or circle track.

Wiseco's Race Engineered Design (RED) philosophy means these pistons aren't just strong; they're smart. They feature horizontal slot oiling in the pin bores, which is crucial for keeping the wrist pin and small-end of the connecting rod properly lubricated, contributing to a longer service life. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, lessening wear on both the piston skirt and the cylinder wall. An accumulator groove is included to help maintain consistent ring seal and power output.

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.
