Wiseco Chevy Small Block 4.040in Bore 1.062in CH -22.00 CC Piston Set

If you're building a high-performance Chevrolet Small Block engine, this Wiseco Professional Series piston set is designed to handle serious power. These pistons are forged from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the demands of racing and severe duty applications. Each piston features a 4.040-inch bore size and a -22.00cc dish volume, which is crucial for achieving your target compression ratio.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that enhance ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The fully machined crown ensures accuracy, and forced pin oiling is incorporated to keep the wrist pins properly lubricated under extreme conditions. This set includes eight pistons, along with premium rings, ready for your heavy-duty build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, ensure you follow the manufacturer's recommended installation procedures and clearances.
