Element 13.5 Tooth Thick Rail Piston

These pistons are a must have part for aegs because while shimming with a normal piston most of the time you will shim all the gears perfectly with 0.1mm of movement and the 0.2mm of clearance between all the gears so you have perfect amout of contact then when you go to put your piston in you will find that the piston doesn't get 100% contact with the sector which mean you have to drop the sper down a little bit in the gearbox which inter reduces your contact with the beval and causes the beval and sper to wear more and can sometimes cause teeth to snap off but you don't have to do this with this piston as it is a wide rack so you can shim perfectly everytime
