About this part

Product Details

If you're building a serious performance Chevy Big Block engine for heavy or severe duty racing, you need pistons that can handle the stress. This set of eight Professional Series forged pistons from Wiseco is designed for just that. They're made in the USA from 2618 aluminum, which gives them improved tensile strength to resist flexing under extreme pressure.

Wiseco machines these pistons with precision ring grooves, anti-detonation grooves, and other features to ensure excellent ring seal, which is crucial for power and longevity in a high-performance application. They also come with an ArmorGlide skirt coating. This isn't just for looks; it helps reduce friction, resist seizure, and makes for quieter operation. The fully machined crown and forced pin oiling further contribute to their durability and performance under demanding conditions.

This set is specifically for a 4.625 inch bore and includes premium rings. Keep in mind these are not CARB approved and cannot be shipped to California. For builders aiming to push the limits of their Big Block, these pistons are a solid choice.
