Wiseco RED Series Chevy LS 4.065in Bore 1.105in CH -10.00 CC Piston Set

Built from 2618 aluminum, these Wiseco RED Series pistons are forged and machined in the USA, specifically for high-performance Chevy LS engines. The RED (Race Engineered Design) series is all about providing the strength and durability needed for demanding racing applications, from drag strips to circle tracks, while incorporating advanced features that give you a competitive edge. Each piston is designed with a dedicated forging to maximize its strength-to-weight ratio, ensuring robust performance without unnecessary bulk.

You'll find horizontal slot oiling in the pin bores, which is a smart design choice to keep the wrist pin and small end of the connecting rod properly lubricated, a critical factor for long service life in a high-stress environment. Wiseco also includes an accumulator groove to help maintain consistent ring seal and power delivery. Plus, the ArmorGlide skirt coating is applied to reduce friction and noise, while also minimizing wear on both the piston skirt and the cylinder wall. This set comes complete with premium rings, so you won't need to source those separately.

This set is designed for a 4.065-inch bore and includes a 1.105-inch compression height, with a -10.00 CC dish volume. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a serious performance LS engine, this set offers a well-built foundation with features aimed at durability and competitive performance.
