Wiseco Chevy Big Block 4.615in Bore 1.270in CH 28.00 CC Piston Set

If you're building a serious performance Chevy Big Block, Wiseco's Professional Series forged pistons are a solid choice. These pistons are made in the USA from 2618 aluminum, which gives them improved tensile strength for handling the demands of heavy to severe duty race applications. They're designed to be a no-compromise component for builders who are pushing their engines to the limit.

Wiseco machines these pistons with precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction and resist seizure, all while keeping operation quieter. The fully machined crown and forced pin oiling are details that show these are built for serious performance where reliability is key.

This set includes eight pistons, each designed for a 4.615-inch bore with a 1.270-inch compression height and a 28.00 CC volume. Keep in mind these are not CARB approved and cannot be shipped to California. You'll want to refer to the manufacturer's installation instructions for proper fitment and assembly details.
