Wiseco Chevy Small Block 4.125in Bore 1.120in CH 3.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious racers and builders who demand improved tensile strength for heavy to severe duty race applications. The 4.125 inch bore size is a common choice for many Chevy Small Block performance builds, offering a good balance of displacement and piston wall thickness. Each piston features precision machined ring grooves, an anti-detonation groove, and additional ring seal improvements to ensure reliable performance under extreme conditions.

Wiseco's Professional Series pistons come with an ArmorGlide skirt coating, which helps reduce friction and resist seizure, while also contributing to quieter operation. The fully machined crown ensures a clean combustion chamber surface, and forced pin oiling is incorporated to keep the wrist pins properly lubricated. This set includes eight pistons, designed to withstand the rigors of high-performance racing where durability and consistent operation are critical.

When rebuilding your top end with these pistons, it's important to note that they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to get the most out of this well-built set.
