JE 279670R Piston Single SRP Pro 2618 (4.030 in. Bore, 1.600 in. CH, -5.00 CC) for FORD Small Block Engine

Description JE 279670R Piston Single SRP Pro 2618 (4.030 in. Bore, 1.600 in. CH, -5.00 CC) for FORD Small Block Engine

JE Pistons SRP Pro 2618 line expands on the premium features of the SRP Pro Series with extremely strong 2618 forged aluminum. The pistons maximize strength and value for small-block and big-block builds.

Forged in the USA, the 2618 aluminum provides the high tensile strength required for high-demand performance applications.

• Proprietary Forged Side Relief (FSR) design minimizes friction and power loss, reduces skirt width, and saves weight with a shorter Wrist Pin
• Ring groove placement maintains a positive seal in high-HP boosted applications, while the stout top land improves strength
• Low-friction skirt coating reduces wear and operating noise while optimizing performance
• Accumulator groove reduces combustion gas pressure and Piston Ring flutter, improving the Piston Ring seal for consistent power
