VHM Pistons

VHM pistons are 100% CNC machined from high quality solid billet material. With our Takisawa lathe we are able to turn elliptical shaped pistons with very high precision.

  • High performance
  • Longevity and keeps performance during lifetime
  • Non-circular piston profile (and inside coating)
  • Resistance to detonation

Important to keep in mind the correct piston-cylinder clearance when mounting a piston, which you can find on the packing list (included in each VHM piston box). We've created an instruction video on how to measure the bore size and thus piston-cylinder clearance.
