Wiseco Chevy Small Block 4.185in Bore 1.120in CH 13.50 CC Piston Set

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

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength over standard aluminum. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is crucial for compression and preventing blow-by. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are details that show these are made for demanding use.

This set includes eight pistons, each designed for a 4.185-inch bore with a 1.120-inch compression height and a 0.927-inch pin diameter. Remember, these are intended for heavy to severe duty performance builds and are not CARB approved, meaning they cannot be shipped to California.
