Wiseco Chevy Small Block 4.035in Bore 1.125in CH -19.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston set is built for Chevy Small Block engines and is designed for builders who need serious durability for heavy to severe duty race builds. These aren't your average pistons; they're packed with features aimed at maximizing performance and longevity under extreme conditions.

Each piston in this set is forged and machined in the USA from 2618 aluminum, which offers improved tensile strength compared to other aluminum alloys. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, all contributing to better combustion efficiency and power. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pin lubricated under high stress.

This set includes eight pistons, each with a 4.035-inch bore, a 1.125-inch compression height, and a -19.00cc dish volume. 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 off-road use or racing applications where emissions regulations may not apply.
