Wiseco Chevy BIG BLK DRAG 1.270 (6238A6) Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series forged piston kit is built for serious racers and builders who demand durability and performance in heavy to severe duty race builds. These pistons are designed to handle the extreme stresses of competition, offering a robust solution for your engine project.

Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high temperatures and pressures. The pistons feature precision ring grooves, an anti-detonation groove, and additional features to improve ring seal, all contributing to better combustion efficiency and reliability. The fully machined crown ensures consistent performance, while forced pin oiling helps keep the wrist pins lubricated. Additionally, the ArmorGlide skirt coating reduces friction, resists seizure, and contributes to quieter operation, making these pistons a well-built choice for demanding applications.

This kit includes a set of 8 pistons, designed for Chevrolet Big Block engines with a 4.310-inch bore and a 1.270-inch compression height. The wrist pin diameter is 0.990 inches. While these pistons are built for extreme performance, please note 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.
