Wiseco Chevy Big Block 4.605in Bore 1.120in CH 23.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Chevy Big Block engines. The 4.605-inch bore size and 1.120-inch compression height are key dimensions for achieving the right compression ratio and piston-to-valve clearance in your build. Wiseco machines these pistons in the USA, ensuring a high level of precision throughout the manufacturing process.

These aren't just basic pistons; they're packed with features for demanding applications. You'll find precision ring grooves designed for improved sealing, along with anti-detonation grooves to help prevent detonation damage. The crown is fully machined for accuracy, and they include forced pin oiling to keep the wrist pins well-lubricated under high stress. The ArmorGlide skirt coating is a notable addition, designed to reduce friction, resist seizure, and contribute to quieter operation, all crucial for engines pushed to their limits.

This set includes eight pistons, the full complement for a V8 engine. While these pistons are built for heavy to severe duty race applications, remember they are not CARB approved and cannot be shipped to California. If you're building a high-performance Chevy Big Block and need robust internal components, this Wiseco set is a solid option.
