Wild Things® Pistons

Küryakyn Wild Things piston kits are the best pistons you can buy for your 95" or 103" Twin Cam.

  • Forged from the highest-grade aluminum alloy designed for piston use —Making them the strongest piston on the market.
  •  The special skirt shape and material means less break-in time, quieter running and a stronger resistance to scoring. The lightweight design results in less power robbed by the forces of inertia and less vibration.
  • Larger and deeper valve pockets will handle larger valves and cams without extra machine work. The decks are slightly raised for a tight squish with stock .045" thick head gaskets. This is extremely important and results in better combustion efficiency and power.
  • The redesigned dome shape on the high-compression piston for stock heads results in less pumping losses (robbed power) and better combustion efficiency and detonation control (pinging).
  • All piston kits come complete with pistons, pins, keepers and rings.
