Wiseco Chevy Big Block 4.600in Bore 1.155in CH 4.00 CC Piston Set

If you're building a serious performance engine for your Chevrolet Big Block, this set of Wiseco Professional Series forged pistons is a solid choice. These are built for heavy to severe duty race applications, meaning they're made to handle a lot of stress and power. They feature a 4.600 inch bore size and a 1.155 inch compression height, designed to work with specific crankshafts and connecting rods to achieve your desired engine displacement and performance characteristics.

Wiseco crafts these pistons in the USA from 2618 aluminum, which offers improved tensile strength compared to other aluminum alloys, making them well-suited for the demands of racing. They come with precision machined ring grooves, anti-detonation grooves, and features to improve ring seal, all contributing to better combustion efficiency and power. The piston crowns are fully machined, and they include forced pin oiling to ensure the wrist pins stay well-lubricated under high loads. Plus, they feature an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly.

This set includes eight pistons, along with premium rings, and is designed to fit a wide range of Chevrolet vehicles from the 1970s through the early 2000s, including models like the Chevrolet C10 Suburban, Impala, and Corvette. Remember, these are intended for racing and performance builds, and are not CARB approved, so they cannot be shipped to California.
