ARRMAFront & Rear Metal Diff Boost Box, ARA210007

5stars given but, these are the first upgraded ones I have tried. There could be better ones but I am very pleased with these so far.

This is an excellent option to put on an arm 3 line I got them for my granite BLXV V3 And Dave performed flawlessly after bashing the heck out of it in session. Super Happy With The Product.

Was bought to replace the rear o. A granite bxl and ended up putting both in to remove the plastic gear from the front

Definitely recommend upgrading to these. Perfect fit in the V3 Granite.

I installed these metal differentials in my Typhon 3S after my rear diff decided to destroy itself. The original unit has metal internals but the input and ring gears are made of plastic; they don't last long. So far these upgraded differentials have proven to be very durable and I've not had a single issue after installing them. The only negative thing I can say about them is the price, which seems a little ridiculous. If you can stomach the cost, they are a very solid choice

Better than the stock

Must have update to the plastic gears

I run 3 cell on asphalt oval track. Easy install, perfect fit, should outlast original plastic gears.
