Wiseco Chevy Big Block 4.560in Bore 1.395in CH -8.00 CC Piston Set

When you're building a serious performance engine for your Chevy Big Block, especially for heavy or severe duty racing, the pistons are a critical component. This set from Wiseco's Professional Series is built with no compromises, designed to handle the extreme demands of competition.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength over standard aluminum. They feature precision ring grooves, anti-detonation grooves, and other features to ensure excellent ring seal under high pressure. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and even makes operation quieter. The fully machined crown and forced pin oiling further contribute to their robust design for demanding applications.

This set includes eight pistons, each designed for a 4.560-inch bore with a 1.395-inch compression height and a 0.990-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders focused on maximum performance and durability in a race-focused Big Block Chevy, this Wiseco set is a solid choice.
