JE Pistons / SRP · 311904

Description

Features & benefits

• Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
• 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.
• Skirt Coat: Skirt Coat reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
• Designed specifically for GM LS7 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.
• 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.
