Wiseco Chevy LT1 4.065in Bore 1.105in CH -20.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston set is a prime example, designed for Chevy LT1 engines that demand serious durability. If you're building a performance engine that needs to handle heavy or severe duty, these pistons are engineered to meet that challenge.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown is ready for your build, and the forced pin oiling ensures the wrist pin stays well-lubricated under stress.

This set includes eight pistons, each with a 4.065-inch bore, a 1.105-inch compression height, and a -20.00cc dish volume. The wrist pin diameter is 0.927 inches. Please note that these pistons are not CARB approved and cannot be shipped to California.
