This is the 14 tooth nylon piston from SHS with factory weight reduction. This piston only has 14 teeth because the tooth before the pickup tooth is missing to fix angle of engagement. It's made of fiber reinforced Nylon and has a full rack of steel teeth. If you need maximum strength and durability with easy installation this is what you want. You don't have to do any cutting or drilling for AOE or "swiss cheesing" Note: To increase this piston's strength even more you can use some ultra thin cyanoacrylate adhesive (super glue) and wick it in around the piston rack.
Note: Because of the gap between the rail segments in this piston it can "catch" in gearboxes with only partial piston rails. If your gearbox only has short rails above the sector gear and not full rails you should consider using a piston with shorter gaps or no gaps in it's rail structure like the SHS 15T.
