Strong and lightweight piston. The body is made from a Dupont polymer material, whilst the rack is made from steel using a metal injection molding process (MIM), very tough and durable. The 14 tooth rack isn't glued to the piston body, I recommend fixing this down with glue or epoxy.
Please note there is a slight design issue that I wasn't 100% happy with, the piston rack is missing about 1mm of material on the pickup tooth, exposing a gap. However I've tested these pistons and they have held up fine under regular builds. I've lowered the price to reflect this. The factory are working to remake the racks. Please see picture.
