ULTIMATE POM Piston Head - Ventilated
- The most advanced piston heads available.
- Feature built in pressure bearings to reduce friction from the spring.
- The ventilated face of the piston head forces air into the piston head and out through holes under the o-ring, forcing the o-rings to expand outwards resulting in maximum compression inside the cylinder.
- This POM version piston head has the same features as the other aluminium piston head, but is made from a lighter material and is intended for high-speed tunings.
