Description

JE pistons machined from high Silicon 4032 alloy for tighter, quieter running clearances (part # 131834 is manufactured from 2618 alloy which by design requires slightly more cylinder to piston clearance). All part numbers utilize an application-specific forging for a more efficient dome shape. These pistons are the perfect choice for your street Hemi engine. Valve pockets have been engineered to accommodate oversized valves and long duration, tight lobe separation cams. The 4032 alloy pistons are precision CNC machined for 5/64, 5/64, 3/16 factory-style rings. 2618 alloy pistons are CNC machined for 1/16, 1/16, 3/16 rings.
