Wiseco Chevy Small Block 4.185in Bore 1.060in CH 12.00 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, built for serious racers and builders who need top-tier performance and durability in their Chevy Small Block engine. These aren't your average pistons; they're designed from the ground up to handle the demands of heavy to severe duty race builds, pushing the limits of what your engine can do.

Each piston in this set is forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for reliable operation under extreme stress. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, ensuring efficient combustion 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 further contribute to their robust design, making them ready for intense competition.

This set includes eight pistons, each designed for a 4.185-inch bore with a 1.060-inch compression height and a 0.927-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Chevy Small Block for racing, these pistons offer a well-built foundation for serious power.
