Quote: A 9" housing must be back-braced for strength, as the tubes are welded to a sheet-metal housing. I bend/straighten NON back braced (circle track) fab 9" housings in my hydraulic fixture very easily.
Because the tubes are press fit several inches deep, then welded around the circumference to a rigid center casting, a Dana 60 housing takes much more pressure to bend/straighten.
The Dana 60 pictured in this thread with Cal-Tracs and blue shocks is a perfect example of an application where a back-braced 9" will not fit and a Dana 60 is probably the best choice.
Why would a back braced nine inch not work there? I run a 8 3/4 back braced with the same 3 inch axle tubes as a nine inch and "blue" shocks with out a problem in my car.
