Invest in 14 bolt or 10 bolt

pay a visit to ls1tech and see back to back dyno pulls from a 10bolt to a 12 bolt or a 9"

the denali 14bolt i got for my 2010 had 342s
I have a set of GM 410 gears for a 14bolt
my old SSS rear had 373s when i got it
you are right they are hard to come by but a GMT400 isnt as expensive and 1320 wheels sells the spacers to run on a gmt800 truck
id go 9" in heartbeat for my 2002 truck as for my 2010 i wanted a direct swap rear
the 10.5" 14bolt still uses a gov bomb

Anyway, I will agree there will be losses with swapping to a bigger axle. For me, whatever loss there is going from a 10 bolt to a 14SF wouldn't be enough to discourage the swap.

Well that was a learning experience. Looked at LS1Tech, LS1, and other forums. Losses were anywhere from 1-2 HP to 30HP (9"). One guy even said that after a swap, he lost 10hp but seemed to gain it back after the axle was broken in.....but I don't think you would do dyno pulls until after the axle was broken in....

the 9.5 rear is a nice option as its bolt in but once you get past the whole bolt in requirements its time to go to a 9"

Bringing this back.
Does ANYONE know if there are any options for disc brakes on the 2500 version of the 9.5" that will clear 15" wheels? It is absolutely imperative that I be able to run my 15s.
AxisT6 will be able to build me a 14 bolt from a 2500 core for a good price, but as I am aware the axle tubes are bigger than my 10 bolt meaning that my caltrac lowers will no longer fit. And the 2500HD brakes have no chance of clearing my Bogarts. Caltrac probably sells the lower brackets to fit the 2500 axle, but I'm stumped on the brakes.
Other option is Ford 9" from Got Torque at around double the cost. But I believe I will be able to use my current backing plates and 1990 silverado brakes.
