Wiseco Chevy LS 4.130in Bore 1.165in CH 6.00 CC Piston Set

If you're building a high-performance Chevy LS engine for serious racing or heavy-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 offers improved tensile strength over other alloys, making them well-built for demanding conditions. Each piston is forged and machined right here in the USA.

These aren't just basic pistons; they come packed with features to improve performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features designed to enhance ring seal. The crown is fully machined for accuracy, and they even include forced pin oiling to keep the wrist pin lubricated under extreme loads. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit when you're pushing an engine hard.

This set is specifically for a 4.130-inch bore with a 1.165-inch compression height and includes everything needed for an 8-cylinder engine. Keep in mind these pistons are not CARB approved and cannot be shipped to California. They are built to withstand heavy to severe duty performance applications, so you can remove your limits with Wiseco's Professional Series.
