JE Pistons SRP 2618 Alloy Forged Pistons

JE Pistons developed the SRP Pro 2618 Series alloy forged pistons over the course of an entire year using 3D modeling with several revisions being tested using FEA (finite element analysis). These pistons offer superior strength for high boost/nitrous racing with alloy forged 2618 aluminum, featuring designs for optimal ring seal (accumulator grooves) and low friction (skirt coatings). Optimize your engine's power for maximum performance with JE Pistons SRP 2618 Series forged pistons. Key features: * Application-Specific—best suited for racing/high-performance builds * Forged using 2618 aluminum, yielding high-tensile strength needed for high-demand performance applications * 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 * Ring groove design placement proven to maintain positive seal in high-HP, boosted applications, along with stout top land thickness for improved strength * Low-friction skirt coating reduces wear and reduces operating noise while optimizing performance * Includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings * Accumulator groove helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power * Value-focused—provides premium features at a more accessible price point than ultra-high-end pistons, suitable for serious racers on a budget
