The anti-reversal latch is a very important part of the AEG gearbox. This part engages the ratchet teeth on the bevel gear in order to stop your AEG gears from reversing when the motor is off and causing damage to your motor or battery. The Modify Safety Anti-reversal Latch is not only to stop the AEG gears from reversing safely and efficiently, but also to allow you to release your AEGs spring safely and quickly.
