Wiseco Chevy BB DRAG 1.270inchCH (6240AS) Piston Shelf Stock Kit

If you're building a serious racing engine for your Chevrolet Big Block, this Wiseco Professional Series piston kit is designed to handle the extreme demands of drag racing. These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for withstanding the intense pressures and heat generated in a high-performance engine. The kit includes everything needed to outfit an 8-cylinder engine with a 4.500-inch bore.

Wiseco has packed these pistons with features aimed at maximizing performance and durability. You'll find precision-machined ring grooves, anti-detonation grooves, and other features designed to improve ring seal and prevent detonation, ensuring every bit of power is extracted efficiently and safely. The piston crowns are fully machined for accuracy, and they come with forced pin oiling to keep the wrist pins properly lubricated under high load. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, contributing to overall engine health and longevity during severe duty applications.

This kit is intended for heavy to severe duty race builds where reliability and performance are paramount. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or a professional mechanic to ensure these pistons are the right fit for your specific build and to gather any additional components you might need for installation.
