Features & benefits

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.
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
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.
Smooth Crown Finish: Deburs all areas around the valve pocket and dome area, to reduces stress risers and prevent hot spots.
Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
Double Pin Oilers: Deliver twice the amount of oil to the wrist pin as compared to the standard single pin oiler.
Designed specifically for 23 Degree Small Block Chevy Engines To provide optimized performance durability
Includes high-quality wrist pins, and locks
Made 100% in the USA
