Wiseco RED Series Chevy Small Block 350 4.020in Bore 1.125in CH -2.00 CC Piston Set

If you're rebuilding the heart of your Chevy Small Block 350 for serious performance, these Wiseco RED Series pistons are built to handle the demands. Designed for engines that see heavy use in racing applications, from drag strips to circle tracks, these pistons are forged from 2618 aluminum, a material chosen for its high tensile strength needed in performance and power-adder scenarios.

Wiseco's Race Engineered Design (RED) process means these pistons are precisely machined for a competitive edge. They feature horizontal slot oiling in the pin bores to keep the wrist pin and small end of the connecting rod well-lubricated, which is crucial for a long service life under stress. 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, while also minimizing wear on the piston skirt and cylinder wall. This set includes 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 is for an 8-cylinder engine and is designed for a 4.020-inch bore with a 1.125-inch compression height. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
