Team Associated 3/32" Carbide Diff Balls (14)

If these are the same part that come with 6 series vehicles they are junk. Maybe they had a bad run of them but several people in our group have had them pit and come apart after only a few races. the chrome looking coating comes of all leaves what looks like a ruck beneath the coating. I've been building ball diffs since the 80's and I properly break them in. I never bark diffs. Earlier balls for 4 and 5 series had no issues.

These are top quality. Compared to acer and other Chinese balls, these built a smoother diff. The price tells the tale here. Dunno on longevity.

There are 14 balls now to suit B5 style diffs, not just 12 as in the description :)

Don't go cheap! You need to stick with these balls. I tried a cheaper T4 rebuild kit, and the diff did not last one heat!
