Wiseco Chevy Small Block 4.030in Bore 1.125in CH -5.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components, especially for high-performance applications. This Professional Series piston set is a prime example, designed for serious racers and builders who demand the best for their Chevy Small Block engine. These aren't just any pistons; they're built with a no-expense-spared approach to deliver custom-level performance and durability, ready to handle heavy to severe duty race builds.

Each piston is forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for the stresses of racing. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating that helps resist seizure, reduces friction, and makes for quieter operation. The fully machined crown is ready for your build, and forced pin oiling ensures the wrist pins stay well-lubricated.

This set includes eight pistons, each with a 4.030-inch bore, a 1.125-inch compression height, and a -5.00cc dish. The included wrist pin diameter is 0.927 inches. Please note that these pistons are not CARB approved and cannot be shipped to California.
