The ULTIMATE extreme performance helical piston made of a 50% stronger polycarbonate resin, with embedded steel teeth specifically designed to work with Extreme torque up helical gears (ref#17164) to give a extreme heavy tuning of 170-190 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 helical piston you get:

In extreme tuneups for power, the forces acting on the piston and gears are huge.
Every little detail in design and size of the components are very important.
When the gear makes first contact with the piston, it slams with great force against the first section of teeth on the piston.
ULTIMATE pistons have been designed with polycarbonate teeth for the first section, to allow it to absorb impact fare better than steel.
As the piston travels further back, the pressure on the teeth increases dramatically, this is where steel teeth gives maximum strength against breakage.
Most be used with appropriate ULTIMATE® upgraded internal components to secure the best performance and durability.
For use with classic Army gearboxes modifications are required.
