Wiseco Chevy Small Block 4.035in Bore 1.250in CH 13.50 CC Piston Set

If you're building a high-performance Chevrolet Small Block engine for serious racing or heavy-duty applications, this Wiseco Professional Series piston set is a solid choice. These pistons are forged and machined in the USA from 2618 aluminum, a material known for its improved tensile strength, making them well-suited for the demands of severe duty performance builds. The set includes eight pistons, each designed to precise specifications for optimal engine function.

Wiseco has packed these pistons with features aimed at maximizing both durability and performance. You'll find precision ring grooves, anti-detonation grooves, and additional features designed for improved ring seal, which helps maintain compression and prevent blow-by. The fully machined crown ensures consistent combustion chamber volume, and the forced pin oiling system helps keep the wrist pins lubricated under extreme conditions. Additionally, the ArmorGlide skirt coating is applied to reduce friction, resist seizure, and contribute to quieter operation, all crucial for engines pushed to their limits.

This set is intended for builders who are serious about extracting maximum performance and reliability from their engine. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, ensure you have all the necessary supporting components and refer to the manufacturer's installation instructions for proper assembly.
