Wiseco Chevy Big Block 4.580in Bore 1.145in CH 15.60 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine for serious racing or severe duty applications, a solid set of pistons is crucial. This Wiseco Professional Series piston set is designed to handle the extreme demands of competitive racing, offering a well-built foundation for your engine's power.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress. Wiseco has incorporated precision ring grooves, anti-detonation grooves, and other features to enhance ring seal, ensuring efficient combustion and preventing detonation. The fully machined crown and forced pin oiling further contribute to the piston's durability and performance under heavy loads. Additionally, the ArmorGlide skirt coating helps reduce friction and resist seizure, leading to quieter operation and extended component life.

This set includes eight pistons, each designed for a 4.580-inch bore with a 1.145-inch compression height and a 0.990-inch pin diameter. Remember that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and reliability in demanding race applications, this Wiseco piston set is a strong option.
