Wiseco Chevy Big Block 4.625in Bore 1.155in CH 28.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine for serious racing or severe duty, these Wiseco Professional Series pistons are a solid choice. They are designed to handle the extreme demands of competitive racing, offering a blend of strength and advanced features to keep your engine running strong under pressure. The pistons are forged from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for withstanding the high combustion pressures found in performance applications.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and other features that enhance ring seal. This attention to detail helps ensure optimal combustion and reduces the risk of detonation. They also come with an ArmorGlide skirt coating, which is designed to reduce friction and resist seizure, contributing to quieter operation and longer piston life even in demanding conditions. The fully machined crown ensures a clean combustion chamber shape, and forced pin oiling helps keep the wrist pin lubricated.

This set includes eight pistons, ready for your next heavy or severe duty race build. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
