Wiseco Chevy SB RED Series Piston Set 4125in Bore 1250in 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, designed to handle the demands of racing and power adder setups. They use a Race Engineered Design (RED) to give you the strength you need with precision features for a competitive edge.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for performance racing and when adding power adders like turbos or superchargers. To ensure optimal lubrication and long service life, they feature horizontal slot oiling in the wrist pin bores. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. You'll also find an accumulator groove that helps maintain consistent ring seal and power delivery. Plus, each set comes with premium rings, so you don't need to source those separately. The ArmorGlide skirt coating is applied to reduce friction and noise, while also minimizing wear on the skirts and cylinder walls.

This set includes eight pistons, rings, and is ready for installation in your performance Chevy Small Block build. Please note that these pistons are not CARB approved and cannot be shipped to California.
