Wiseco Chevy LS 4.165in Bore 1.165in CH -2.00 CC Piston Set

These Wiseco Professional Series pistons start with a 2618 aluminum forging, chosen for its improved tensile strength, which is crucial when you're pushing an engine hard. They're machined right here in the USA to tight tolerances, featuring precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal. This attention to detail means you get consistent performance and durability, even in heavy or severe duty race applications.

You'll also find an ArmorGlide skirt coating on these pistons. This isn't just for looks; it's designed to reduce friction, resist seizure, and help keep things quieter under load. The fully machined crown and forced pin oiling are also part of the package, ensuring proper lubrication and heat management where it counts. If you're building a serious LS engine for racing or demanding performance use, these pistons are made to handle the stress.

This set includes eight pistons, each designed for a 4.165-inch bore with a 1.165-inch compression height and a -2.00cc dish volume. The pin diameter is 0.927 inches. Please note that these pistons are not CARB approved and cannot be shipped to California.
