Wiseco Chevy LS 4.125in Bore 1.110in CH -25.00 CC Piston Set

If you're building a high-performance Chevrolet LS engine for serious racing or heavy-duty use, a solid set of pistons is crucial. This Wiseco Professional Series piston set is designed to handle the extreme demands of competitive racing and severe duty applications. They are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is essential for components that endure high combustion pressures and temperatures.

Wiseco has packed these pistons with features aimed at maximizing performance and durability. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, ensuring efficient combustion and preventing blow-by. The crown of each piston is fully machined for accuracy, and they incorporate forced pin oiling to keep the wrist pins properly lubricated under extreme conditions. A notable feature is the ArmorGlide skirt coating, which helps reduce friction and resist seizure, contributing to a quieter operation and longer component life.

This set includes eight pistons, each with a 4.125-inch bore and a 1.110-inch compression height, along with a 0.927-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders aiming to push the limits of their LS engine, these Wiseco pistons are a well-built option designed for the most demanding race builds.
