Description
SHS Steel Anti-Reverse Latch
This is a steel anti-reverse latch from SHS, a replacement component for AEG gearboxes. SHS is a widely used maker of affordable gearbox internals, including gears, pistons, springs and latches.
A retailer listing for the SHS anti-reversal latch describes a precision steel latch with a stainless steel axle, made for SHS version 2 and version 3 gearboxes and described as a universal part that suits many compatible gearboxes.
What the anti-reverse latch does
The anti-reversal latch is a small sprung lever that engages the bevel gear. It lets the gears turn forward but stops them spinning backwards under the force of the compressed spring when the motor stops, which protects the motor and lets the gearbox hold its position between shots.
Standard latches can wear or crack over time, especially in replicas with stronger springs or high rates of fire. A failed latch can lead to the gears spinning backwards and a jammed or damaged gearbox, so replacing a worn latch is a sensible piece of preventative maintenance.
Fitting
Fitting this part means opening the gearbox, so it is best suited to players with technical experience or to an airsoft technician. Always remove the battery and magazine first, take photographs as you dismantle, and keep track of small springs and screws, particularly the trigger and anti-reversal latch springs.
After reassembly, test the replica on every fire mode at a safe backstop and have it chronographed before taking it to a game.

Compatibility
Published specifications describe this latch as made for SHS version 2 and 3 gearboxes and suitable for many compatible gearboxes. Our original listing advises checking fit with your gearbox and related parts. Gearbox parts vary between versions and manufacturers, even where the names look similar. Always confirm your replica’s gearbox version and maker before ordering, and if in doubt, contact us with your replica model.
Care and maintenance
Use a proper airsoft gearbox grease, applied sparingly, rather than household oils, which can attract dirt or damage plastic parts. Check moving parts for wear and correct shimming whenever the gearbox is open for servicing.
Keep the replica’s battery in good condition, as a weak battery makes the motor work harder and puts extra load on every part of the drivetrain.
Who is it for?
This latch suits technicians and experienced players servicing or upgrading V2 or V3 gearboxes, especially in replicas with stronger springs.
Please note: Fitting by an experienced player or technician is recommended. The latch spring is not mentioned in our listing.
