Wiseco Chevy Small Block 4.035in Bore 1.000in CH -25.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance builds. They feature a 4.035-inch bore and a 1.000-inch compression height, with a -25cc dish volume. This specific material choice is key because 2618 aluminum offers improved tensile strength, which is crucial for handling the extreme pressures and temperatures found in high-performance engines.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal enhancements to ensure optimal performance and durability. The fully machined crown and forced pin oiling further contribute to their robust design. Additionally, the ArmorGlide skirt coating helps reduce friction and resist seizure, while also contributing to quieter operation. These pistons are designed to withstand severe duty applications, making them a solid choice for builders who need reliable components for their custom engines.

This set includes eight pistons, designed for Chevrolet Small Block engines. While these pistons are built for extreme performance, please note they are not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder or refer to Wiseco's installation guidelines for specific details regarding your build.
