Our pistons are manufactured exclusively from premium quality extruded aerospace 4032 & 2618 aluminum alloy. These materials provide a far superior product over OEM pistons.

Wrist Pins are included at no extra cost. Valve pockets can be machined to accept oversized valves.

    Features Include:
  • High strength lightweight aluminum forgings
  • Fully CNC machined and balanced to +/- 1 gram
  • Lateral gas ports
  • Double pin oilers, force fed from oil ring add twice the amount of oil from the cylinder wall to the wrist pin
  • Accumulator Groove, collects residual gasses during combustion and alleviates top ring flutter while increasing ring seal
  • Contact Reduction Grooves, that limit the piston/cylinder contact during high temperature and RPM
