Description
Machined from high silicon 4032 alloy for tighter, quieter running clearances. All part numbers utilize an application specific forging for a more efficient dome shape. These pistons are the perfect choice for high-performance street/strip Hemi engines. 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 made for 1/16, 1/16, 3/16 rings.
