ARRMA HD Input Gear 13T, ARA311031 Large

This input gear is a great OEM replacement. It drops in exactly like the original, and performs as expected. A metal alternative would be a nice upgrade, but these are affordable and work perfect.

Doesn't fit in arrma 3sblx crazy it's the part# in the exploded viewEdit: I made an error part is intended to be larger as you drive the truck it wears perfect

For Senton 3s BLX

This part was exactly what I needed, identical to the stock one I took off to replace. Item arrived very quickly, actually 1 day earlier than expected, in Arrma Factory Packaging, sealed, brand new part. Ready to bash again, and again!

Haven’t broke it yet. :)

Was the correct piece

For the low cost it’s an amazing part. I use 3s in my vorteks and it surprisingly lasts a long time. Quiet and well made

I give it 3 stars bc if you do not bash hard they will last. Just go ahead and spend the extra $8 and get the Metal input gear. You will have to get the metal differential gear also not much $. The composite differential housing works fine but if you are going to bash it is worth the extra money. You will only have to spend it once. My big rock is upgraded to 4s and has not striped the metal ones even landing under power. 3s typhon and a couple lands under power and it will strip the composite gears.the Metal set up is a little louder but so what.

Bei unserem Big Rock war das Zahnrad "rund", also als Ersatz das hier bestellt und eingebaut.Jetzt flitzt er wieder durch die Gegend.
