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

Verbaut wurden diese Differenziale in einem Arrma BigRock 3S und bisher alles unauffällig. Machen das was sie sollen nur mit deutlich mehr Stabilität. Bin sehr zufrieden, lediglich der Preis ist deutlich zu hoch.

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!

I put these in my granite after upgrading the power system and slipper. Smooth and quiet. Worth the cost for me.

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
