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.
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.
