Wiseco Chevy Small Block 4.030in Bore 1.062in CH 13.50 CC Piston Set

Forged from 2618 aluminum, these Wiseco Professional Series pistons are built for the demands of serious racing and heavy-duty performance builds. The 4.030-inch bore size is a common specification for many Chevrolet Small Block engine builds, and the 1.062-inch compression height is crucial for achieving the correct deck height and compression ratio with your chosen crankshaft and head combination.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements to ensure optimal performance and durability under extreme conditions. The ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and extended engine life. The fully machined crown and forced pin oiling further enhance their capability for severe duty applications, making them a solid choice when you're pushing the limits of your engine.

This set includes eight pistons, designed to work with a 0.927-inch pin diameter. While these pistons are engineered for high performance, please note they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
