Correct
@Caman96. I'm comparing the axle assembly for a semi-float 8.5" 10 bolt (GVWR 7200-type that is designed for fitment with the 11" drums, which I would need if I were to upgrade to the 11" JB6 drums) versus a semi-float 9.5" 14 bolt. (In that case the brakes are the same - both 11" JB6 - so no weight difference from the brakes. And previously in this thread I looked at how a pair of 11" drums is only 10 lbs heavier than a pair of 10" drums; so even going from a 10-bolt 8.5 semi-float with JB5 10" drums to a 14 bolt 9.5 semi-float with JB6 11" drums only adds up to an increase of 40 lbs, or 58 lbs if both axles had a True-Trac limited slip.)
And I am not considering, for the sake of this thread or for my Tahoe, the 14 bolt full-float 10.5". That's of course a different horse.
I care, for one. Weight is one reason I've been unsure about the 14 bolt - and now I know, with real figures; and 30 lbs difference (or 48 lbs with a True-Trac) is what those numbers tell me. I figured I'd share those real numbers since we've been talking about it and because I think real numbers are more useful than supposition, rumor, or echo chamber. Each thing you change can potentially affect something else. Weight can be one factor. I'm not the type who thinks bigger is necessarily better. And I like to do my homework.
