JE designs are specifically engineered for extreme applications up to, and including, professional competition

• JE Auto forged pistons from JE Pistons are the result of over 75 years of industry leading experience extended to our range of premium forged pistons for 23 Degree Small Block Chevy Engines JE Pistons are designed for each specific engine and racing application to provide the ultimate combination of durability and performance. From drift track to drag strip, JE Pistons’ performance is proven in victory lane time and time again. Equipped with the following custom level features
• Smooth Crown Finish, Contact Reduction, Dual Velocity Gas Ports, and Pin Fit. JE Auto Pistons are engineered, forged and machined 100% in the USA
• 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.
• 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.
• Custom Level Features: Smooth Crown Finish-Deburs all areas around the valve pocket and dome area to reduces stress risers and prevent hot spots.
• Standard Features:Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
• 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
