Wiseco Chevy Small Block 4.130in Bore 1.120in CH 13.50 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built with improved tensile strength to handle the demands of severe duty race applications. They feature a 4.130-inch bore and a 1.120-inch compression height, designed specifically for Chevrolet Small Block engines. The fully machined crown ensures precise combustion chamber volume, while the precision ring grooves and additional sealing features help improve ring seal for better performance and durability.

Wiseco has included an ArmorGlide skirt coating, which helps reduce friction and resist seizure, leading to quieter operation and extended piston life. For added reliability, these pistons also feature forced pin oiling to ensure the wrist pin stays well-lubricated under high stress. These are serious pistons for serious engine builds, designed to remove limits and withstand heavy use.

This set includes eight pistons, ready for your next high-performance engine build. 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.
