Saw it on ebay for $50.00 is it worth it?

Ask yourself if you need it or not? If you do not need it, dont buy it. I mean the gear diff works pretty good right?

ya it does. just wanted to know what it did so much better for $50.00

you can find them cheaper than that

Mainly they are made for racers for the adjustability. But myself I'd rather spend $45 on an FLM sealed diff so you can tune by different thickness diff fluid. I run one in my Slash and Rustler and they are awesome.

Also I've heard the ball diffs don't hold up very well on brushless power bashing.

Ball diff's are just a nother pain in the ass, i ordered 2 new stampede metal gear diff's because 4 systems on my first one took it's toll, if these Break, im going with the FLM

you can adjust a normal traxxas gear diff with different oils, no?
a ball diff is definatly an upgrade for a racer as you can tune it
without pulling apart anything (pop a driveshaft out thats all).

not worth $50 though in my opinion and not for bashing obviously
the gear diff is tougher.

just a note most ball diffs set up correctly and maintained well, are
more than capable of taking brushless power, and more to the point more
power than is allowed in most classes of racing.

The traxxas diffs are not sealed so they cannot be tuned with different oils.. You can mod them to be sealed its not hard to do.. basically they leak at the bearings so you have to get a oring seated in there to seal it.. and some silicone around the case..

I've looked at the ball diffs for the rustler, but they are not worth the money.. if you are a serious racer maybe, but for bashing no.. the traxxas diffs work fine the way they are, but could use some adjustability.. I will be doing that mod over the winter months..

Wow...Ya I'm thinking about an FLM diff and transmission case, but that's about $100 alone right there! Probably I'll just get the diff first then go from there btw how does the FLM transmission case hold up when butt-diving? Does it bend/warp at all?

No, it shoudnt your pretty serious if you do bend it

You can run diff fluid in the stock rustler diff. I've done it for a while now until I got the FLM diff housing.

The only problem is, is the stock diff housing is not sealed, so your diff fluid leaks out and makes a nasty gooey mess all inside the tranny case.

If your wanted to seal the stock diff yourself so you can tune with fluids then look here. Especially have a look at the link in post #30 which shows a larger picture of page 133 in the magazine that he posted. http://monster.traxxas.com/showthrea...leville+washer

i've got mine still in my toolbox after buying it 4 years ago... put it in a while back and hated trying to figure out how to adjust it right so i just put the gear one back in...
