Details: This Piston uses a strong plastic which is even tougher than some Nylon Fiber reinforced pistons. I suspect that these Prometheus Pistons are made of polyacetal copolymer, but I will have to consult a plastics expert for clarification. (I will update this description once I find out)
The pickup tooth is very beefy, and all of the teeth are heavily reinforced. Since the factory omitted a tooth, modifying the teeth for AoE correction may not be necessary for this Piston.
The metal rack is thoroughly heat treated. The racks take quite a bit of force to pry out of the Piston, and the Piston body has support which prevents the rack from caving in.
Interestingly, these Prometheus Hard Pistons were first made in 2004. Many Chinese companies have cloned this Piston, but they haven’t even come close to replicating the same quality as the original. This is because Laylax uses superior quality materials in all of their Piston molds; as well as precision machining and QC.
