Several people have mentioned That a back brace is a waste of time. Not exactly. It will not help ring and pinion life. It's real purpose on both 8 3/4 and 9" rears is to brace the housing so that it won't tow in and bend. Good power and dead hook can/will bend them. By the time you start bending the 8.75 housing, you've already been breaking ring and pinions. For the money it costs to bandaid an 8.75, you could have built a Dana for it and forgotten about it.
