Wiseco Chevy Small Block 4.035in Bore 1.250in CH -1.70 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston set is built for serious racers and builders who need top-tier performance and durability for their Chevy Small Block engine. These aren't just any pistons; they're designed and built to handle the demands of heavy to severe duty race builds, giving you the confidence to push your engine's limits.

Each piston in this set is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for high-performance engines. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown ensures accuracy and consistency across the set, and forced pin oiling helps keep the wrist pins lubricated under extreme conditions.

This set includes eight pistons, each designed for a 4.035-inch bore with a 1.250-inch compression height and a 0.927-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
