Default Ball Diff or Gear Diff for the B4?

Hey all,

So I accidentally bought a gear diff transmission case for my B4, which obviously doesn't fit with the existing ball diff gear I have. To be honest, I hate messing around with ball diffs. I was just wondering how many people out there are running gear diffs in their various reincarnations of a B4, and how they find it? I have 2 B4's so perhaps it would be a good idea for me to have one with a gear diff and the other with a ball diff?

Welcome peoples thoughts, thanks heaps

I can't speak from personal experience but my good friend just switched over to a gear diff and said he likes it better than the ball diff. He was the TQ and won the main at our club race on Saturday so it must be working ok. He said he is running it with 4000wt. Fluid FYI .

I run mine with either 3000wt diff fluid or grease depending on track conditions. Put it in and see how you like it, I actually prefer it over the ball diff.

I run and prefer the ball diff. Some people I have talked to are the opposite and run the gear diff. I have also heard that ball diff is better for low grip and the gear diff is better for high traction and carpet.

high traction dirt or astro or carpet = geardiff

I run a gear diff with 1000K oil on a low-medium traction track. I love it, such low maintanance and works really well. Can't say anything bad about it really!

I do the opposite others do.
I run a gear diff outside on big 8th scale tracks, and ball diff inside.
Both work really well. If I had a choice thou id run a ball diff.
The ball diff seems more tunable than a gear diff. Loose dirt I like to run a gear diff over a ball diff.

also both joel and reedy run ball diffs in there b4.1 at ride. I reckon that it would be best if you ran a ball diff.

Thanks for that. As mentioned above, I already have a ball diff in both my B4s. In any case, the gear diff is on its way.
