Wiseco Chevy Big Block 4.615in Bore 1.270in CH 48.70 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Chevy Big Block engines. The 4.615-inch bore size is specific for certain Big Block applications, and the 1.270-inch compression height works with many popular crankshafts to achieve the desired deck height and compression ratio. Each piston features precision ring grooves, an anti-detonation groove, and additional features designed to improve ring seal, all contributing to better combustion efficiency and power output.

Wiseco's Professional Series pistons are made in the USA with a focus on durability for heavy to severe duty race builds. They come with premium rings and feature an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and operate more quietly, which is especially beneficial in high-stress engine conditions. The fully machined crown ensures accuracy and consistency across the set, and forced pin oiling helps keep the wrist pins lubricated under extreme loads.

This set includes eight pistons, designed to be a complete solution for rebuilding or upgrading your Chevy Big Block engine. 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.
