Wiseco Chevy LS 4.005in Bore 1.165in CH 10.00 CC Piston Set

These Wiseco Professional Series pistons are forged from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the demands of heavy to severe duty race builds. Each piston is machined in the USA to precise specifications, including the crown, ring grooves, and anti-detonation features, all aimed at improving ring seal and overall performance. The ArmorGlide skirt coating is applied to reduce friction and resist seizure, contributing to quieter operation and longer life under extreme conditions.

Designed with forced pin oiling, these pistons ensure proper lubrication to the wrist pin, a critical factor in high-performance engines. The set includes premium rings, and the precision ring grooves are engineered for optimal sealing. With a 4.005-inch bore and a 1.165-inch compression height, these pistons are specifically made for Chevrolet LS engines that are being built for serious racing applications where durability and consistent performance are paramount.

This set is intended for builders who are looking to push the limits of their engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
