Wiseco RED Series Chevy LS 4.075in Bore 1.105in CH -20.00 CC Piston Set

When you're building a high-performance Chevy LS engine for serious racing, whether it's drag strip or circle track, you need pistons that can handle the stress. The Wiseco RED Series is built for exactly that. These aren't your average pistons; they're forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard, especially with power adders like turbos or superchargers.

Wiseco's Race Engineered Design (RED) philosophy means these pistons are optimized for strength and durability. They feature dedicated forgings that allow for an engine-specific strutted design, maximizing strength while keeping weight down. You'll also find horizontal slot oiling in the pin bores, which helps keep the wrist pin and connecting rod small end well-lubricated, contributing to a longer service life. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall. Each set comes complete with premium rings, so you don't have to hunt for compatible ones.

This set is designed for a 4.075-inch bore and features a 1.105-inch compression height with a -20.00cc dish. An accumulator groove is included to help maintain consistent ring seal and power delivery. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
