Wiseco Ford Small Block 302 4.030in Bore 1.090in CH -9.00 CC Piston Set

If you're rebuilding the heart of your Ford Small Block 302 for serious racing or heavy-duty performance, a strong set of pistons is where you start. This Wiseco Professional Series piston set is built to handle the demands of severe duty applications, giving you the confidence to push your engine hard. Each piston is forged and machined right here in the USA from 2618 aluminum, a material chosen for its improved tensile strength under extreme conditions.

Wiseco has packed these pistons with features that matter for performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is critical for compression and preventing blow-by. The fully machined crown ensures consistent combustion chamber volume, and forced pin oiling helps keep the wrist pins lubricated under high loads. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and even makes operation quieter.

This set is specifically sized for a 4.030-inch bore with a 1.090-inch compression height and a 0.927-inch pin diameter. Remember, these pistons are not CARB approved and cannot be shipped to California. They are designed for use in competition vehicles and are not intended for street use where emissions compliance is required.
