well you answered you own question right there man ,,, a 9 1/4 in ring gear axle is quite a bit more beef than a chevy 8 and somthing inch ring gear,,, and ring gear beef translates to spider gear beef for the most part wich is what you weld ,,,, 10 bolt p.o.s. rear end ,,, personaly i think its the worst rear end chevy ever put under the rear of a fullsize rig the 12 bolt is stronger granted marginaly but marginaly is still stronger... 12 bolt rear should have been under half ton rigs not this 10 bolt stuff
of corse opinions are like buttholes everybody has one and i know mine stinks 2 but it is my opinion and i am sticking to it :thumb:
