ARRMAFront & Rear Metal Diff Boost Box, ARA210007

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

This product is fantastic. Just one very small discrepancy...there is some slight resistance to the rotation of the gear out of the box. None to worry. A guy on youtube suggested shimming the outer casing to the diff. I did so and the resistances was gone (3MM washers worked GREAT!) Do this and your diff replacement will be PERFECT! Be sure to lightly grease the gearing!

Love these and they are such a good upgrade over the plastic stock ones.

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

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

Better than the stock
