Wiseco Chevy LS 4.145in 1.165in CH -23.00 CC Piston Set

Starting with a 2618 aluminum forging, these Wiseco pistons are machined in the USA to handle the demands of serious racing and heavy-duty builds. The 4.145-inch bore size is a common upgrade for many LS engine configurations, and the 1.165-inch compression height combined with a -23.00cc dish volume is designed to achieve specific compression ratios when paired with appropriate cylinder heads and crankshafts.

Wiseco's Professional Series pistons are packed with features aimed at improving performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features designed to enhance ring seal. The fully machined crown ensures accuracy, and the forced pin oiling system helps keep the wrist pin lubricated under extreme conditions. A notable feature is the ArmorGlide skirt coating, which Wiseco developed to reduce friction, resist seizure, and contribute to quieter operation, all critical factors when pushing an engine hard.

This set includes eight pistons, ready for your next severe-duty LS engine project. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal results, always refer to the manufacturer's installation instructions and recommended assembly procedures.
