These gears require disassembly of the gearbox to install, and as such, they are recommended only for advanced users.

About Our Airsoft Gears, Gear Sets & Gear Ratios

The absolute bread and butter of your gearbox, the gears are an important part of your AEG's operation and ratios need to be accurate for endless rounds of smooth firing. Stock up on your mods, replacements or spares and explore our full range of airsoft gears and gear sets, from top brands like ASG and Modify. 

As simple as it is, It’s vital to bear in mind that the higher the quality of your airsoft gears, the longer your AEG is going to last. However it’s also worth considering that massively up-rated steel gears are pretty useless if you're still using a polymer-toothed piston, so be sure to up-rate the rest of your gearbox as you improve vital parts. 

Airsoft gear sets are rated by a 'ratio' value. This is essentially how many turns the motor needs to make for a complete cycle. There are plenty of airsoft gear ratio calculators available online to help you work out exactly what you need, but a rule of thumb is a smaller airsoft gear ratio will result in a higher rate of fire, at the cost of more work for the motor.
