Wiseco Chevy Small Block 4.060in Bore 1.125in CH -5.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is a prime example, designed for Chevy Small Block engines and built to handle serious racing and heavy-duty use. If you're building a performance engine that needs to withstand severe duty, these pistons are a solid choice.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding conditions. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The fully machined crown is also a notable detail. For added durability and smoother operation, they come with an ArmorGlide skirt coating that helps resist seizure, reduces friction, and makes for quieter running. The design also includes forced pin oiling to ensure the wrist pin stays well-lubricated under high stress.

This set includes eight pistons, each with a 4.060-inch bore and a 1.125-inch compression height. The pin diameter is 0.927 inches. Please note that these pistons are not CARB approved and cannot be shipped to California. They are intended for racing applications and heavy-duty builds where performance and durability are paramount.
