JE Pistons Chevrolet Small Block Stock Car 4.060in Bore 1.250 CD Flat Top -3.8cc - Set of 8 377964

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

  • 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.
  • Dual Velocity Gas Ports: A combo 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, reducing carbon build up of traditional gas ports.
  • 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
  • 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
