Wiseco RED Series Chevy LS 4.005in Bore 1.105in CH -20.00 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 boosted setups. They are forged from 2618 aluminum, a material chosen for its high tensile strength, which is essential when you're pushing an engine hard.

These pistons feature Race Engineered Design, meaning they're optimized for strength and performance. The horizontal slot oiling in the wrist pin bores ensures the wrist pin and connecting rod small end stay well-lubricated, which is crucial for a long service life under stress. Wiseco uses dedicated forgings for each engine application, allowing them to create a strutted design that maximizes strength while keeping weight down. To further reduce friction and wear, the skirts are coated with ArmorGlide, which also helps quiet down operation. An accumulator groove is included to help maintain consistent ring seal and power delivery.

This set includes premium rings, so you won't need to source those separately. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance builds and are a solid option if you're rebuilding a Chevy LS engine for serious use.
