Wiseco Chevrolet Small Block Gen I 4.125in Bore 3cc Dome 1.000 CH Piston Kit - Set of 8

These Wiseco Professional Series pistons start with a 4.125-inch bore size, specifically crafted for Chevrolet Small Block Gen I engines. They are forged from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for handling the intense pressures found in racing applications. The 3cc dome design and a 1.000-inch compression height are key dimensions that dictate how the piston interacts with the cylinder head and camshaft timing, making them vital for engine builders aiming for specific performance targets.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features designed to improve ring seal. This attention to detail helps ensure consistent combustion and reduces the risk of blow-by, even under severe duty conditions. Additionally, the ArmorGlide skirt coating is applied to resist seizure, reduce friction, and contribute to quieter operation, all while the forced pin oiling system ensures the wrist pin receives adequate lubrication.

This set includes eight pistons, along with premium rings, ready for heavy to severe duty race builds. While these pistons are built for extreme performance, please note they are not CARB approved and cannot be shipped to California. They are designed to withstand the demands of high-performance engines where durability and consistent power delivery are paramount.
