Smooth Crown Finish, Contact Reduction, Dual Velocity Gas Ports, and Pin Fit. JE Auto Pistons are engineered, forged and machined 100% in the USA

• 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.
• Custom Level Features: Smooth Crown Finish-Deburs all areas around the valve pocket and dome area to reduces stress risers and prevent hot spots.
• Designed specifically for 23 Degree Small Block Chevy Engines To provide optimized performance durability
• Dual Velocity Gas Ports-combination of both lateral and vertical gas ports, providing the advantages of both. DVGP's provide positive gas pressure to the back side of the top ring w/out the carbon buildup of the traditional vertical style.
• 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
• Standard Features:Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
