Wiseco Chevy Big Block 4.615in Bore 1.215in CH 40.00 CC Piston Set

When you're rebuilding the heart of a Chevy Big Block for serious racing, the pistons are where you can't afford to cut corners. This Wiseco Professional Series piston set is built from the ground up for heavy to severe duty applications, giving you the confidence to push your engine to its limits. Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under extreme conditions.

Wiseco has packed these pistons with features that matter on the track. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is critical for power and longevity. The crown is fully machined for accuracy, and they even come with forced pin oiling to keep the wrist pins well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, all while contributing to quieter operation.

This set includes eight pistons, ready to be installed in your Chevrolet Big Block engine. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builds demanding the utmost in performance and durability, this Wiseco set is a solid choice.
