Features & benefits

Includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings
Forged in the USA using 2618 aluminum, yielding tensile strength and minimal thermal expansion
Designed specifically for Nissan VK56DE 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
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.
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.
Skirt Coat: Skirt Coat reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
