Wiseco Chevy LS 4.070in 1.165in CH -20.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons offer improved tensile strength, making them a solid choice for demanding Chevrolet LS engine builds. The 4.070-inch bore size is a common upgrade for LS engines, and the -20.00 CC dish volume is designed to achieve specific compression ratios when paired with appropriate cylinder heads and crankshafts. This set includes eight pistons, each featuring precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal and overall engine performance.

Wiseco's Professional Series pistons are built for heavy to severe duty applications. They come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown ensures accuracy, and forced pin oiling is incorporated to keep the wrist pin lubricated under high stress. These pistons are designed and machined in the USA, reflecting a commitment to quality and durability for serious racers and builders.

When rebuilding or modifying your LS engine for performance, these Wiseco pistons are a key component. They are designed to work with a 0.927-inch wrist pin. Keep in mind that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
