Wiseco Chevy LS 4.185in Bore 1.165in CH 6.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and severe duty LS engine builds. The 4.185-inch bore size is a common upgrade for LS engines looking to increase displacement and power. This set is designed to handle the stress of heavy use, offering improved tensile strength and durability.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation features, and additional ring seal enhancements. The crown is fully machined for a clean combustion chamber surface. For reduced friction, quieter operation, and improved seizure resistance, the piston skirts are treated with an ArmorGlide coating. Forced pin oiling is also incorporated to ensure proper lubrication of the wrist pin under high loads.

This set includes eight pistons, each with a 1.165-inch compression height and a 0.927-inch pin diameter, making them suitable for many popular LS engine configurations. While these pistons are built for extreme performance, please note they are not CARB approved and cannot be shipped to California.
