Wiseco Chevy LS 4.010in Bore 1.165in CH 5.00 CC Piston Set

If you're building a high-performance Chevrolet LS engine for serious racing or heavy-duty applications, you need pistons that can handle the stress. This set of eight forged pistons from Wiseco is designed specifically for that purpose. They feature a 4.010-inch bore and a 1.165-inch compression height, making them suitable for many popular LS engine configurations.

Wiseco crafts these pistons from 2618 aluminum, a well-known material for its improved tensile strength, which is crucial for withstanding the extreme pressures found in race engines. They're fully machined in the USA, including precision ring grooves, anti-detonation grooves, and features designed to improve ring seal. You'll also find an ArmorGlide skirt coating, which helps reduce friction and resist seizure, contributing to quieter operation and longer life under demanding conditions. The crown is also fully machined, and the pistons include forced pin oiling for better lubrication.

These pistons are intended for heavy to severe duty performance builds where durability and reliability are paramount. Please note that this part is not CARB approved and cannot be shipped to California. For optimal installation and performance, always refer to the manufacturer's detailed specifications and recommended build procedures.
