Wiseco Chevy BIG BLCK DRAG 1.270CH 4310A Piston Shelf Stock

This is a single Wiseco Professional Series forged piston designed for Chevrolet Big Block engines with a 4.310 inch bore. Wiseco builds these pistons in the USA from 2618 aluminum, which gives them improved tensile strength for demanding race builds. They come with precision ring grooves, anti-detonation features, and additional ring seal improvements to help keep things sealed up tight under pressure.

You'll also find an ArmorGlide skirt coating on this piston. This coating helps reduce friction, resist seizure, and makes for quieter operation. The fully machined crown and forced pin oiling are also notable features that contribute to their durability in heavy to severe duty performance applications. These are well-built pistons intended for serious racers and builders looking to push their engines hard.
