Features & benefits

Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
Designed specifically for Chevrolet Small Block 23 Degree Engines. To provide optimized performance durability
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
Includes high-quality wrist pins, and locks
Made 100% in the USA
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.
Contact Reduction: Reduce the amount of contact area against the cylinder wall when the piston "Rocks over". Contact reduction also serves to disrupt the flame travel into the crevice area causing a reduction in detonation.
Double Pin Oilers: Deliver twice the amount of oil to the wrist pin as compared to the standard single pin oiler.
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.
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.
