2024 Edition Notes from Retro Arms
We made some useful improvements into our CNC gearboxes V2:
- Spring holders have grooves, so the springs for tapped plate and trigger switch will not jump off.
- Added groove for safety lever, so it will hold during installation.
- Added groove for trigger spring, for better fitting.
- AOE control hole.
- Sockets for bushings/bearings have smaller diameter about -0,02mm (7,98mm), for non-overturning the bushings during installation. The socket edges are cutted down for better installation.
- We enhanced grooves for wiring for 1mm, you can now use wirings with 2,5mm diameter.
- Added protecting edge for wiring against the motor.
- All threads are now shaped instead of cutted for better strength.
- Both of the gearbox parts are centered by milled grooves and edges.
- Added hole for releasing anti-reverse latch.
- For better durability, we added more material around cylinder head part of the gearbox, this was the most critical part and we added 100% more material where is huge radius.
- Added groove for anti-reversal latch spring, so it will not jump off.
- Outer edges are now cutted off.
- You can find what type of sockets gearbox have on the outside part of the gearbox (8mm or 9mm).

Second one I've purchased. Love not having to worry about blowing off the front of my gearbox. Love the routing for wires. ETUs fit nicely. If you're buying nice internals why not put them in something that's going to last.
I use this in my favorite builds the most solid gear shell there is.
Precision CNC’d, looks great and it nice and smooth. Would definitely recommend for an upgraded gearbox
Just wish it had the hole for the bolt catch
whats the diffrence between a stock gear box and a retro arms
a standard gearbox has many intolerances as well is made from cheaper weak metals which always fail eventually. Especially if you upgrade your aeg theres added stress from the increased cycles, cycle time, and over all increased abuse. They all crack eventually. A retro box will never crack and since it is not off spec, upgrading is super easy and makes the process 10 times easier. You do not have to radius the gearbox, nor dremmel out stupid trigger contact threads to seat a mosfet. It is the best upgrade for any aeg. It is a shame to spend $500 on parts for your gearbox shell to break and potentially break other internal parts to just have to re build it. With retro, you build it once and forget about it with confidence.
