Wiseco Chevy Small Block 4.035in Bore 1.250in CH -5.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is a prime example, built for serious racers and builders who need parts that can handle extreme conditions. If you're putting together a heavy or severe duty race engine for a Chevy Small Block, these pistons are designed to meet that challenge.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds. They feature precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown is ready for your specific build requirements, and they include forced pin oiling to keep the wrist pins lubricated under high stress.

This set includes eight pistons, each designed for a 4.035 inch bore with a 1.250 inch compression height and a -5.00cc dish volume. They use a 0.927 inch pin diameter. Keep in mind these are not CARB approved and cannot be shipped to California.
