Features
- Accumulator Groove: A specialty groove between the top and second ring provides added volume for blow-by gases. This helps reduce pressure between the rings, improving top ring seal and minimizing ring flutter at high cylinder pressures.
- Designed specifically for Chevrolet Big Block 454 Engines. To provide optimized performance durability
- Double Pin Oilers: Deliver twice the amount of oil to the wrist pin as compared to the standard single pin oiler.
- Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
- Includes high-quality wrist pins, and locks
- 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
- Smooth Crown Finish: Deburs all areas around the valve pocket and dome area, to reduces stress risers and prevent hot spots.
- 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.

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately.
