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!
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.
Reviewers are split on these 14-ball carbide diff balls. One reviewer rates them 2/5, reporting that balls from the same batch pitted and came apart after a few races, with the coating flaking to reveal a rough surface beneath; they suspect a bad production run rather than a design flaw. Two reviewers rate them 5/5, praising a smoother diff compared with cheaper Chinese balls and saying they outlast a budget rebuild kit, though one admits longevity is unknown. A verified owner notes the set contains 14 balls, not the 12 stated in the description, which suits B5-style diffs. The sample is small and the reviews conflict on durability.
