Heavy-Duty Polycarbonate Piston M170 by ASG

This high-performance heavy-duty piston by ULTIMATE from ASG is built for demanding upgrade builds reaching up to 190 m/s. It's made from reinforced polycarbonate resin that is 50% stronger than regular pistons and features 10 steel teeth in the rear half for maximum resistance to stress.
The front polymer teeth effectively absorb impact, while the steel rear teeth endure extreme loads, ensuring optimal performance in even the most demanding setups.
