Wiseco RED Series Chevy LS 4.125in 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 action or circle track competition, you need pistons that can handle the stress and deliver consistent power. The Wiseco RED Series pistons are built for exactly these kinds of demanding applications. They are forged and machined right here in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that are pushed hard or running forced induction.

Wiseco's Race Engineered Design (RED) philosophy means these pistons aren't just strong; they're smart. They feature dedicated forgings that allow for an optimized, engine-specific strutted design, giving you the best possible strength-to-weight ratio. You'll also find horizontal slot oiling in the pin bores, which is a smart detail that keeps the wrist pin and the small end of the connecting rod properly lubricated, helping to ensure a long service life for these critical components. Plus, the ArmorGlide skirt coating is applied to reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall. This set comes complete with premium rings, so you won't have to hunt for compatible ones.

An accumulator groove is also included to help maintain consistent ring seal, which directly translates to sustained power output. These pistons are designed to give you a competitive edge, offering the durability and precision machining that performance engine builders rely on.
