Wiseco RED Series Chevy LS 4.020in Bore 1.105in CH -10.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components for performance applications. This RED Series piston set is built for Chevy LS engines, designed to handle the demands of racing and high-power builds. These aren't your average pistons; they're crafted using Race Engineered Design (RED) principles to give you a real edge on the track or the street.

Each piston in this set is forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing serious power. They feature a dedicated forging design that optimizes the strutted structure for the best strength-to-weight ratio possible. To further reduce friction and wear, the skirts are coated with ArmorGlide, which also helps quiet things down. You'll also find horizontal slot oiling in the pin bores, ensuring your wrist pins and small-end connections stay well-lubricated, which is key for long service life. An accumulator groove is included to help maintain a consistent ring seal, keeping power delivery smooth and reliable.

This set includes eight pistons, all machined to a 4.020-inch bore size with a 1.105-inch compression height and a -10.00cc dish volume. Importantly, this kit comes complete with premium rings, so you won't need to source those separately. Please note that these pistons are not CARB approved and cannot be shipped to California.
