Description
Accumulator Groove, Smooth Crown Finish, Combo 2, Contact Reduction, Double Pin Oilers, and Pin Fit. JE Auto Pistons are engineered, forged and machined 100% in the USA
Features & benefits
- 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.
- 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.
- Designed specifically for 23 Degree Small Block Chevy Engines To provide optimized performance durability
- 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
- Includes high-quality wrist pins, and locks
- Made 100% in the USA
- 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.
- Smooth Crown Finish: Deburs all areas around the valve pocket and dome area, to reduces stress risers and prevent hot spots.
- 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.
