Wiseco Chevy Big Block 4.615in Bore 1.060in CH 28.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine for serious racing or severe duty applications, a strong set of pistons is crucial. This Wiseco Professional Series piston set is designed to handle the extreme demands of competition. They are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress and heat.

These pistons feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal, which is vital for maintaining compression and preventing blow-by in a high-output engine. The crown is fully machined for accuracy, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated. Additionally, they include an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly, all contributing to better performance and longevity under harsh conditions.

This set is intended for a 4.615-inch bore with a 1.060-inch compression height and a 0.990-inch pin diameter. Remember that these pistons are not CARB approved and cannot be shipped to California. For a severe duty race build, these Wiseco pistons offer a well-built foundation.
