Wiseco Chevy LS 4.020in 1.165in CH -17.00 CC Piston Set

Wiseco is well-known for building tough, reliable engine components, especially for high-performance applications. This Professional Series piston set is a prime example, designed for Chevy LS engines that demand serious durability. If you're building a race engine or a severe-duty performance street machine, these pistons are made to handle the stress and heat that comes with pushing your engine hard.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength compared to cast aluminum. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is critical for power and engine longevity. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, makes operation quieter, and resists seizure, all contributing to a more robust and efficient engine under load.

The fully machined crown ensures accuracy, and the forced pin oiling system keeps the wrist pins lubricated. Wiseco designed these pistons to withstand heavy to severe duty performance applications, meaning they're built for the long haul in demanding builds. This set includes eight pistons, ready for your next engine project.
