Default Underdrive gearing for ar44

Does anyone have a part number of underdrive gears for my wraith 1.9 with ar44 axles? I can only seem to find overdrive gears for some reason.

Yes that's the part number I have which is way to big for the rear diff on the ar44 axles

I thought they were compatible with that axle, so????? I thought SSD made an underdrive set too but I couldnít find anything when I looked. Hopefully someone knows of one because now Iím confused.

I only know of Overdrive gears for the AR44 axles not any underdrive.

As far as overdrive gears, your options are....

1. Boom Racing - Asiatees
2. Hot Racing - eBay
3. SSD RC - eBay

I'm guessing its the same principal going overdrive in the front as as opposed to underdrive in the rear? Any one of those brands better than the other? Also do I need any other parts or will that bolt up to my stock diff internals?

Underdrive would require a larger ring gear which isn’t possible with AR44’s, or a smaller pinion which would be weak since it’s so small. Overdrive is available and the only option.
