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.
• Ultra Groove: Specialty ring groove machining process that provides near perfect groove flatness and surface finish. Tolerances are held to the millionths of an inch.
• 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.
• Double Pin Oilers: Deliver twice the amount of oil to the wrist pin as compared to the standard single pin oiler.
• Designed specifically for Chevrolet Small Block 400 Engines. To provide optimized performance durability
• Includes high-quality wrist pins, and locks
• Made 100% in the USA
• Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
