I haven't had a problem with the ball diff. Now I admit the last ball diff I ran was 10+ years ago in a f102 but the fgx ball diff out of the box lowered my lap times, increased corner speed, made the car rotate the turns better, increased rear traction, and made the car more driveable on corner entry and exit. Maybe I got lucky and picked out a good one.

The ball diff in mine is the worst ball diff I have ever seen.

For the ball diff, the Zero diff fits, but needs the diff outer gear instead of the belt pulley. It is a much better piece.

strange, mine is probably one of the worst i have had! like Fred said its like a pepper grinder, either it slips or locks up. I am pretty sure its the thrust bearing. what surface are you on? I think that it will be the best choice but i need to make it work like it supposed to.
I wonder if there is a v1 and a v2 for the ball diff. I thought about trying the roller diff but the ball diff has done me well so far.

I had to take the gear diff apart and sand the fronts and backs of the beveled gears to get rid of the molding flash. Then I put it back together with no fluid and made sure it felt free with no binding and no gear skipping. Then tore it back apart and put in the fluid. I green slimed the half shafts every time they came back out.

I did the same thing and my diff is pretty smooth...but I did notice like Fred that there is a lot of drag in the o-rings even before I assembled the diff...I've built 3 different gear diffs from 3 different manufacturers and noticed the same thing with all of them. Just came to think that was the nature of a gear diff eventually.

I built the v2 gear diff for my sakura zero and it had noticeably less o ring drag compared to the v1 but is was still not as smooth as the spec r or xray diff. I only installed 2 of the large shims instead of three so a little o ring pressure was relieved. Maybe this helped a little.
