Part Type

Engine Piston Kit

• Designed specifically for Chevrolet Big Block Engines. To provide optimized performance durability
• Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
• Includes high-quality wrist pins, and locks
• Lateral Gas Ports: This process mills slots into the top of the top ring groove and provides a pathway for combustion pressure to get behind the top ring. Resulting in increased ring seal and is most common in circle track applications.
• Made 100% in the USA
• Pin Fit: The pin bore is precision honed to attain an exact pin clearance. Clearances typically range from .0003 to .0010 between the wrist pin and pin bore.
• Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin
• Vertical Gas Ports: Machined gas ports channel combustion pressure behind the top ring for improved cylinder sealing and reduced blow-by under high load. Common in drag racing applications where maximum ring seal is critical.

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only.
