Good product
Works great in my Arrma senton 3s BLX good parts and direct fit. They already come with 80k weight lube in them

Fits the Arrma Granite 3s Blx
This item fits the Arrma Granite 3s Blx (ARA4302V3) with no issues! It does make a difference on how this thing handles & makes it more stable. Make sure the differentials are properly filled with enough of fluid & grease the outside gears before installing. Comes prefilled with 10k.

Metal Differential Boost Box for 1:10 Arrma Granite 3S BLX
So far, so good! I have replaced the composite version quite a few times. Hopefully this will make the drive train last longer. I also purchased the power module boost box with the metal slipper clutch spur gear as part of the assembly. I am cautiously optimistic with this set up. My Arrma Granite 3S BLX truck is super fun to drive, and the stock set-up works great, but the composite input gear and composite crown gear only hold up for so long. Same thing can be said for the composite 57 tooth spur gear in the slipper clutch assembly. Metal gears in place of the composite gears should add durability to the fun equation! ... show more

READ THIS REVIEW!!
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! ... show more

Strong differential.
Not much to say about these high quality Arrma products. They are heavy and stout. No issues so far. Fit as they should with no modifications.

Nice upgrade for your Arrma vehicle
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 ... show more
