Wiseco Chevy Small Block 4.140in Bore 1.120in CH 3.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston set is a prime example, designed for Chevy Small Block engines where durability and performance under extreme conditions are critical. If you're building a serious race engine or a heavy-duty performance street machine, these pistons are engineered to handle the stress.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is essential for withstanding the high pressures and temperatures found in performance engines. They feature precision ring grooves, anti-detonation grooves, and other features to ensure better ring seal, which helps maintain compression and prevent blow-by. The crown is fully machined for accuracy, and they come with forced pin oiling to keep the wrist pins properly lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly.

This set includes eight pistons, designed for a 4.140-inch bore with a 1.120-inch compression height and a 0.927-inch pin diameter. They are built to withstand heavy to severe duty performance applications, meaning they are ready for demanding race builds. Please note that these pistons are not CARB approved and cannot be shipped to California.
