i went two years on a 10 bolt. wrinkle walls nitrous out of the hole lifting the tire on a 4200 pound truck. that had 180k before i even built it. trutrac/richmond/ta girdle.

the 14 bolt needs the same love. the g80 in my SS is broke and that was when it was stock.

 

OK, condensed version; the 9" hybrid or the 14 bolt SFA, which is/ was stronger................

 

9 inch

 

hmm, gotta learn more about this 9 incher..............

 

Sorry, but not familiar with the 9" hybrid. What is it, what does it come in?

 

It comes in the new trucks that have the 6.2litre engine, so I guess it has to be good...............

 

Interesting...anyone have a link or details on it's internals? Hybrid? a beefed up 8.6 10 bolt?

 

10 bolt = 8.625"
14 bolt = 9.500"
Hybrid = 9.000"

 

Well, the 8.6 is really no different than the 8.5 10 bolt introduced in the early 70's other than different carrier bearings diameters.
The 9.5 14 bolt is completely different design that is often confused with the original 14 bolt 10.5", which is a bad boy.
So the Hybrid is a totally new design is what I'm asking? Or like the 8.5 to 8.6 "upgrade"?

 

Not familiar with that 8.5, 8.6 upgrade, the 9" a totally new design/ inception and is referred to a a hybrid design; exactly why I don't know................
