ASG AEG M170 Polycarbonate Piston - Red

  • $19.95


The ULTIMATE extreme performance piston is made of a 50% stronger polycarbonate resin, with embedded steel teeth specifically designed for high-speed tunes and extremely heavy tuning of 150-190 m/s.
All dimensions of the piston have been reworked to fit perfectly inside ULTIMATE gearboxes and give 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 the ULTIMATE gearbox.
  • Perfect combinations of polycarbonate teeth and steel for impact-energy absorption and strength.
  • The reinforcement bar gives superior structural strength to the piston teeth.
  • Optimal angle for the first contact between piston and gear.
  • 50% stronger polycarbonate (than the ULTIMATE high-performance piston)


In extreme tune-ups whether for speed or power, the forces acting on the piston and gears are huge.
Every little detail in the design and size of the components is 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 far better than steel.
As the piston travels further back, the pressure on the teeth increases dramatically, this is where steel teeth with a reinforced longitudinal bar give maximum strength against breakage.
