Metal Main Central Axle Drive Shaft Upgraded Spare Parts for 1:12 124019 124018 RC Car Spare Accessories

Beware the screw are losses but that's ok need to pack with diff grease anyway

This will go in my 124010 speed run build great value for $$ havn’t opened it up yet if i find anything bad will repost

Doesn't work with the 144011 which has the thicker dogbones and shafts. Works fine with the standard 144001 front cv shafts I had from a parts kit. Sadly I have no skinny dogbones to go with them.There are unbroken edges on most of the gears but the teeth and other machining is pretty nice. The diffs were both well shimmed; no in and out play. They had enough grease to lube but were not packed by any means. Most of the screws weren't terribly tight. Would recommend a tightening of all of them before running it hard.

Good replacement for WL 1/12 124017 V2 however the extra pinion motor gear that it comes with is 27t tooth for this but could be used if you are able to move the motor and would increase the top speed at the expense of cogging. The whole build up of this is really a good deal and comes all assembled. It does include the upgraded metal drive gear that was previously plastic. The mesh doesn't seem to be as smooth as the plastic one. My original had the screw on the front drive gear break off in the shaft. I recommend that you Grease your diff internals if you open it up this far as ive already powdered 2 diffs on this car, the diffs are not adequate for the speed 40+mph and power of the 124017 as it was all borrowed from lower powered models

Look at the photo, see how the oot drives are not even straight? When you get them, you will need to disassemble them and use Loctite on the screws, holding the outdrives onto the devil/sun gears. But it doesn’t even matter because they will still spin loose under the talk of the vehicle.. also, the gears do not come greased. You’ll need to grease them.. no matter how much I reassemble them and glue them they would not stay together as soon as the car started rolling. Dog bones also locked up and ground inside the outdrives.. bottom line is do not buy these. They are trash and just a massive headache and you will be constantly disassembling front and rear transmission of your car.

The media could not be loaded. Upgraded differential is NOT compatible with upgraded dog bone axels

No issues with install and has been working perfect so far.

Old diffs broke constantly. bought these: problem solved. Totally worth it. Buy them.
