AZTECH XTREME Nylon Polymer Piston Body


This piston body literally ticks every single box for the ultimate AEG Piston.

Custom made Fiber reinforced PA66 Polyamide (Nylon) Lightweight Piston, hardened Cr12MoV rack, strengthened and weight reduced with large windows in the low stress areas, this is DSG and high rate of fire ready out of the box.

Our strengthened and reinforced, lightweight and over engineered piston features:

-Lightweight ported and reinforced ultra strong PA66 Polymide Piston
-Cr12MoV hardened 14 tooth rack

We have over engineered the piston as much as physically possible. nearly doubling the amount of material to the highest stress point at the back of the piston bridge to increase support for the pick up tooth with 80% more material than every other piston we have measured and tested. We opted for Cr12MoV hardened steel as it is the strongest metal we could use to ensure maximum life and outright breaking strength.


Main properties of PA 66 Nylon include:

  • High strength and stiffness at high temperature
  • Extreme light weight out of the box.
  • Good impact strength, even at low temperature
  • Good abrasion and wear resistance
  • Excellent oil and solvent resistance
  • Good fatigue resistance

It is highly recommend to bond the steel rack to the body of the piston for high performance builds.

We recommend a high strength Gorilla Grip 2 part araldite epoxy as an absolute minimum or

We recommend using JB Weld Original Steel reinforced Epoxy for the highest strength bond available.
