Threadlock (Blue) is still required

Toss it in any build you want and expect it to last longer than anything in the gearbox.

The Whisper MK.II (Mark 2) is the strongest polymer piston head on the market.

  Very low coefficient of friction and extremely high impact resistance

• As durable as an aluminum piston head

  Strong enough to strip cheap allen keys before the screw gives out. 2mm hex drive

• CNC Aircraft Grade 7075 Aluminum Threads

• Flat Front Face Edge to Edge to Reduce Dead Air Zone
  Good for setups requiring maximum useable air volume.

• FKM Oring 
  For better performance under high heat usage
