bought some ue diffs off ebay
 

Is it anyone here that sold them? They are 6 spyder. From what I read on Robins site, they are pretty indestructible.

Paralyzed, thanks for the offer.

Does anyone know what gears I would order if I needed to rebuild them? They are used so I really don't know what they have been throuh.

"Super 6" diffs are just ofna hyper diffs. Here are brand new ones with bonus hyper bulkheads for $33 > http://www.ebay.com/itm/NEW-OFNA-HYP...item1e774bbc2a

If you payed more than $33 a piece you got ripped off.

Crap, you are right. You didn't respond to my offer so snatched a set on eBay. Oh well, thanks for the info =D

How do I turn them into super 8s?

That''s an 8 spider ofna hyper diff. They are pretty rare, they sell for not much less than the ue store, and they come without pinions.

I was simply going to sell you the super 8's and replace them with hyper 7 diffs (the $33 ones) and pocket $80, but I decided I didn't want to tear down my maxx to get them out, they are inside FLM combo bulks on an assembled truck.

In theory the super 8's are stronger because they spread the load to 8 spider gears instead of 6, and they have an aluminum case instead of plastic, but in my opinion anything that would break a 6 spider will break an 8 spider. They just look cooler and have a bigger number.
