Wiseco Chevy LS 4.020in Bore 1.165in CH 10.00 CC Piston Set

If you're building a high-performance Chevy LS engine for serious racing or severe duty applications, you need pistons that can handle the stress. Wiseco's Professional Series forged pistons are designed for just that. They start with 2618 aluminum, which is forged and machined right here in the USA, giving them improved tensile strength to withstand extreme conditions.

These pistons come packed with features that serious builders look for. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is critical for power and longevity. They also include Wiseco's ArmorGlide skirt coating, which helps reduce friction, resist seizure, and keep operation quieter. The fully machined crown and forced pin oiling further contribute to their durability and performance under heavy loads.

This set is for an 8-cylinder engine, with a 4.020-inch bore, a 1.165-inch compression height, and a 10.00 CC dish volume. Remember, these are intended for racing and heavy-duty use, and they are not CARB approved, meaning they cannot be shipped to California.
