PISTONS SET OF 8

JE Pistons are custom-forged racing pistons, designed, forged, and machined in-house for quality control. They utilize advanced CNC machining and Finite Element Analysis (FEA) for testing and race simulation. These SRP Professional pistons feature a lightweight FSR forging, making them up to 20% lighter than traditional equivalents. Made from high-silicon 4032 aluminum alloy, they offer reduced piston-to-wall clearance and quiet operation. Designed for normally aspirated or moderate forced induction/nitrous applications, they include accumulator grooves for improved ring seal, a high-performance skirt coating, and low drag performance piston rings.
