Wiseco Chevy Big Block 4.560in Bore 1.270in CH -19.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance builds. The 4.560-inch bore size is specific to Chevy Big Block engines, and the 1.270-inch compression height, combined with a -19.00cc dish volume, helps achieve specific compression ratios tailored for high-performance applications.

Wiseco machines these pistons in the USA, focusing on precision in every detail. You'll find precision ring grooves designed for improved sealing, an anti-detonation groove to help prevent detonation damage, and features that enhance ring seal. The crown is also fully machined for accuracy. For added durability and reduced friction, these pistons come with an ArmorGlide skirt coating, which helps resist seizure, lowers friction, and contributes to quieter operation. The design also includes forced pin oiling to ensure the wrist pin receives adequate lubrication under extreme conditions.

This set includes eight pistons, designed to withstand severe duty and heavy use. While these pistons are built for extreme performance, please note they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
