Wiseco RED Series Chevy LS 4.015in Bore 1.105in CH -20.00 CC Piston Set

Starting with a 4.015-inch bore and a 1.105-inch compression height, this Wiseco RED Series piston set is built for serious performance in Chevy LS engines. These aren't your average pistons; they're forged from 2618 aluminum, a material chosen for its tensile strength, which is crucial when you're pushing the limits with racing or adding significant power. The Race Engineered Design (RED) philosophy means these pistons are specifically crafted to give you a competitive edge, whether you're on the drag strip or the circle track.

Wiseco machines these pistons in the USA, and they've included some smart details to ensure longevity and performance. The horizontal slot oiling in the pin bores keeps the wrist pins and connecting rod small ends well-lubricated, which is vital for preventing wear under high stress. They also feature dedicated forgings for an optimized strutted design, balancing strength with a manageable weight. Plus, the ArmorGlide skirt coating works to reduce friction and noise, while also cutting down on cylinder and skirt wear. You get a set of eight pistons, complete with premium rings, so you won't need to hunt for those separately. An accumulator groove is also built in to help maintain consistent ring seal and keep power delivery smooth.

This set is designed for performance applications and includes everything you need to get started with the pistons and rings. Please note that these pistons are not CARB approved and cannot be shipped to California.
