Wiseco Chevy BB DRAG 1.120inchCH (6243A6) Piston Shelf Stock Kit

If you're building a serious Chevrolet Big Block drag racing engine, this Wiseco Professional Series piston kit is designed to handle the extreme demands of competition. These pistons are forged and machined right here in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress and heat, which is crucial for sustained performance on the track.

Wiseco has packed these pistons with features to ensure durability and performance. You'll find precision ring grooves, anti-detonation grooves, and other ring seal improvements to keep combustion contained and efficient. The fully machined crown ensures a consistent shape, and forced pin oiling helps keep the wrist pin properly lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, all contributing to a more reliable and powerful engine build. These are built for heavy to severe duty race applications, meaning they're ready for the kind of abuse that wins races.

This kit includes a set of eight pistons, each designed for a 4.560-inch bore with a 1.120-inch compression height and a 0.99-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
