Ultimate Polycarbonate Piston
Ultimate Polycarbonate Piston.
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.
