Wiseco Chevy BB DRAG 1.120inchCH (6243A3) Piston Shelf Stock Kit

If you're building a serious Chevrolet Big Block drag racing engine, these Professional Series forged pistons from Wiseco are a solid choice. They're made in the USA from 2618 aluminum, which gives them improved tensile strength needed for the high demands of racing. This set is designed for a 4.530 inch bore and features a 1.120 inch compression height, with a 0.990 inch pin diameter.

Wiseco packs a lot into these pistons. You'll find precision ring grooves, anti-detonation grooves, and other features to improve ring seal, which is critical for performance and durability. The fully machined crown is ready for your build, and the pistons come with forced pin oiling to keep things lubricated. Plus, they have an ArmorGlide skirt coating that helps reduce friction and resist seizure, making for quieter operation and better longevity under stress.

This kit includes a set of 8 pistons, along with premium rings. They are built to handle heavy to severe duty race applications, so you can push your engine hard. Keep in mind these are not CARB approved and cannot be shipped to California.
