Wiseco Chevy Big Block 4.530in Bore 1.215in CH 48.70 CC Piston Set

This is a set of eight Wiseco Professional Series forged pistons designed for Chevrolet Big Block engines. You get pistons with a 4.530-inch bore, a 1.215-inch compression height, and a 48.70cc dish volume. These pistons are built from 2618 aluminum, which is known for its improved tensile strength, making them well-suited for demanding race applications.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements to ensure reliable performance under heavy stress. The piston crowns are fully machined, and they feature forced pin oiling for better lubrication. Additionally, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. These are designed for severe duty race builds where durability and consistent performance are critical.

Keep in mind that this piston set is not CARB approved and cannot be shipped to California. If you're building a high-performance engine for racing or heavy-duty use, these pistons are a solid option from a well-known manufacturer.
