Blomiky 2 Pack QZJ05 Q903-ZJ06 Metal Differential Spare Parts for Blomiky Q903 1/16 Scale Brushless RC Truck Q903 Differential 2

Sheared off one of the tabs that the axle slots into on both the front and rear plastic diffs that came stock on the brushed 1/16 Laegendary Sonic truck. Ordered these metal upgraded ones on Monday night, and in the meantime cannibalized what could be salvaged from each one to cobble together at least one working unit and then converted the truck to rwd only. Only had the chance to test out the Frankenstein diff just once because the new ones came in early Wednesday afternoon. Got home and checked them out first thing. Seem to be built rather well. Metal gears inside and out, and just because I wanted to be sure about it, I opened them both up and they already had some grease in the housing as well. Fit and worked just as perfectly as the oem pieces did, but at about almost right at half the cost since a single new metal diff from Laegendary is like $15 but the ones here from Blomiky were only $18 for two, so it’s definitely a no-brainer as to where I’ll be getting my next set when I need some more!

These differentials seem well made, durable and fit prfectly. The only problem is they are just a little to wide for my 1:16 4x4 (Laegendary Sonic) and when assembled, they put a little too much pressure on the front axles causing the steering servo to no function. Works great in the rear though!!

Perfect fit brushless 1/16 truck

Didn't fit my car, but they can be ground down a bit if you know what your doing.

They don't last very long.

Looks like a good quality upgraded part to replace the plastic ones it came with even has some grease in it

Parte original de muy buena calidad. Como nuevo mi RC con estos diferenciales. Entrega a tiempo. Recomendado.

Used for sonic 1/16 scale rc. There exactly what I needed
