Wiseco Chevy LS 4.125in 1.165in CH -23.00 CC Piston Set

If you're building a high-performance Chevy LS engine for serious racing or heavy-duty use, a strong set of pistons is crucial. This Wiseco Professional Series piston set is designed for those demanding applications where reliability and durability are paramount. These aren't your average pistons; they're crafted from 2618 aluminum, which offers improved tensile strength over other aluminum alloys, making them well-suited for the stresses of racing.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that enhance ring seal. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The fully machined crown ensures consistent combustion chamber volume, and forced pin oiling helps keep the wrist pins lubricated under extreme conditions. This set is built to handle heavy to severe duty performance builds, giving you the confidence to push your engine's limits.

This set includes eight pistons, designed for a 4.125-inch bore and featuring a 1.165-inch compression height. Remember, these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity in your build, ensure you follow all manufacturer installation guidelines and use appropriate supporting components.
