Wiseco Chevy LS 4.005in Bore 1.311in CH -9.70 CC Piston Set

If you're building a serious performance Chevrolet LS engine, Wiseco's Professional Series forged pistons are designed to handle the extreme demands of racing and heavy-duty applications. These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for high-stress engine environments. The set includes eight pistons, each featuring a 4.005-inch bore and a 1.311-inch compression height, with a -9.70 CC dish volume.

Wiseco has packed these pistons with features to ensure reliability and performance under severe duty. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The piston crown is fully machined for accuracy, and they incorporate forced pin oiling to keep the wrist pins properly lubricated. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and contribute to quieter operation, all while being well-built for the long haul in demanding builds.

This set is intended for builders who are pushing their LS engines to the limit. Please note that these pistons are not CARB approved and cannot be shipped to California. For a complete build, ensure you have all necessary supporting components and refer to the manufacturer's installation instructions for proper fitment and assembly.
