The cast aluminum girdle IS a good idea. This will keep the maincap's deflection under control. A local guy's ABS reluctor ring was actually interfering with his stamped steel (stock) 10-bolt cover launching his car on slicks. He found this out when he tore it apart to fix the broken posi/ring&pinion. An aftermarket cover could have prevented this as they preload the bearing caps preventing them for excess deflection when the carrier torque sideways.
Get the cover, if you upgrade to a 12-bolt, 8.8", or 9", you can always sell your TA cover on a board.

I'd like to see pictures of this. I feel pretty confident we will see ZERO pictures of a twisted tube on a 10-bolt.
Was this a rear that someone tried to weld the tubes to the housing?

I weld all of the 'serious effort' differentials that I build.... and not one of them has failed the the past 18+ years.
And BTW..... the tubes are not 4130. They are either 1021 or 1022 ish ERW tubing.

Its a tricky balance to actually get the 'set' preload correct, without adding deflection into (or other wise known as pinching) the main cap into the bearing race when its cold..... but then again, if there is not enough (and it then heats up)..... it wont be enough and the bearing race will still taco from the carrier trying to spit the parts out the back.
Having met, and getting to know the originator/designer of this product (he is a friend of the business).... his intent was good.... and even he said it was just a "money maker" to sell a design that would be a great BANDAID, but its not a "FIX."
