More info

The gears in your AEG gearbox are responsible for cycling the piston - they're available in a couple of different types i.e. ratios, gearox designs etc. It is critical that you go for the correct gears for your gearbox, for example if you have an L85, SR25, M14, P90 or Thompson etc then you have to go for a specific set of gears. That said, the vast majority of guns use standard gears i.e. V2 or V3.

Once you've got the correct type, then you've got to choose your ratio. Stock/standard gears are 18:1 meaning that the bevel gear has to turn 18 times to cycle the piston once. The lower the ratio the higher the ROF (rate of fire), whereas the higher the ratio the higher the torque. 16:1 is basic high speed, although you can go right the way up to 10:1...just depends on how ridiculous you want your gun shooting!

These 18:1 gears from SHS are perfect for replacing stripped gears where you do not require any gains in rate of fire. If you are looking for higher speeds in ROF (rate of fire), then you would be far better off with the 16:1 or 13:1 variants. They are constructed out of steel and CNC machined for superior quality and performance. 18:1 gears are the standard ratio found in most out of the box guns, and are smoother-cycling than higher speeds due to the additional teeth. They are also higher-torque, making them perfect for short-stroke setups.

Installing high speed gears requires care and attention, as if the shimming is off then you can end up burning out motors, destroying gears & pistons etc. If you are in any degree unsure, we would strongly recommend leaving it in to a professional. Installation requires disassembly of the gearbox.
