The ULTIMATE extreme performance piston made of a 50% stronger polycarbonate resin, with embedded steel teeth specifically designed for high-speed tunes and extreme heavy tuning of 150-190 m/s.
All dimensions of the piston has been reworked to fit perfectly inside ULTIMATE gearboxes and gives a smooth low friction performance.
The length has been adjusted to make a perfectly even contact between the first gear and the first teeth of the piston preventing breakage and minimizing wear.
With ULTIMATE Extreme performance piston you get:
Increased strength.
Increased durability.
Low friction.
Perfect fit in ULTIMATE gearbox.
Perfect combinations of polycarbonate teeth and steel for impact-energy absorption and strength.
Reinforcement bar gives superior structural strength to the piston-teeth.
