Wiseco RED Series Chevy Small Block 350 4.020in Bore 1.250in CH -11.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components for performance applications. Their RED Series pistons are built using Race Engineered Design principles to give you the strength and durability that performance engines demand, along with precision machining for a competitive edge. These pistons are available for many popular domestic V8 engines, forming the foundation for everything from drag racing to circle track builds.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its tensile strength, which is crucial for high-performance racing and engines with power adders. To help maintain optimal lubrication for the wrist pin and the small end of the connecting rod, they feature horizontal slot oiling in the pin bores. This design detail is important for ensuring a long service life. The dedicated forgings allow for an engine-specific strutted design that maximizes the strength-to-weight ratio, meaning you get robust construction without unnecessary bulk. Each set comes complete with premium rings, so you won't need to source those separately. An accumulator groove is also included to help maintain consistent ring seal and power delivery.

This specific set is designed for Chevrolet Small Block 350 engines with a 4.020-inch bore and a 1.250-inch compression height, featuring a -11.00cc dish. Please note that these pistons are not CARB approved and cannot be shipped to California.
