The 8mm mod is B4 carbon hub extenders installed on the rear hubs. It raises the outer link raising the roll center.

It helped me to keep the rear of the truck in control on low grip hardpacked tracks.
how hard I try but my rear does not wash out.

Has anyone else done this to their diffs?

Does anyone have some of the Ofna shims, any extras they would like to sell?

Seems everywhere is out, wouldn't mind getting some.

I still have some. I'll mail them tonight no charge.

would these work? http://www.mcmaster.com/#standard-shims/=hjtq09

Thanks Krio, I really appreciate it. Let me know if you still need my address.

sizes are right from what I can configure under the metric column.

Makes me wonder ... I know someone looking for diff rings for a vehicle that is hard to find. What kind of "Shims" would you want to simulate the durability of a diff ring. (off topic I know, curious though)

I just picked up a used SC10 and this is one of the mods i plan on doing during my tear down.

Let us know how it goes.

Holy Crap. The last 3 pages has been about the 8mm hub mod and a flush of people who can't even read the post below theirs that answers their question about it.

Read. The. Others. Posts. (even wildcherry's unfortunately) They've said what the damn mod does 3 times in 3 pages. /rage

so ... um ... yeah ...

what does the mod do?

SO where do I add 8mm of what???

wait you mean theres a mod you can do with the hubs that will make my sc10 better???????????

I also keep hearing about these v2 diff's, how does that work as well?

Hell, I am still in awe that there are these things in the shape of a circle that rotate ...
