VHM pistons are entirely CNC machined from high-quality materials and have a non-circular profile to prevent engine blockage. They guarantee high performance, longevity and continued high performance throughout their service life. This piston has an internal coating that reduces micro-welds, reduces friction on the pin, prevents seizure of the bore and ensures excellent heat conduction. What's more, this piston is fitted with special Z-clips that prevent the clips from turning and damaging the groove.
This piston can be used as a direct replacement for A kits.
For non-A models, this piston must be used with a special VHM insert for flat-head pistons.
