The two tone has looked good on every other generation so whynot

I agree

Isn't there a 9.5 from an Avalanche or something that would bolt in?

07+ subs, avy, and tahoe with tha axn axle code. But they are 4x the cost for an older 9.5. For my setup I will have to modify the mounts some anyway why not start with a cheaper axle. Hummer H2 9.5” axle is also a drop in if you can find one but you wold need to get axle shafts and brakes from a Silverado max.

Saving money for a 6 lug 14 bolt. I stopped by a wrecking yard today and painted the one I wanted it’s from a 94 model gmc

What gear ratio is the 14 bolt semi float you currently have that's too narrow? I'm wanting to swap my 10 bolt for a semi float 6 lug 14 bolt, and I wouldn't be opposed to running wheel spacers.... I'm wanting to also go to 4.10 gears in the process.

It’s 4.10s. I’ll swap the gears into the other axle housing. its 3" narrower than the 10 bolt under mine and 6" narrower than the width of the Dana 44 with gmt800 unit bearings.

Picked up a 6 lug 14 bolt this afternoon from a 94 model 4x4 68" WMS 3" wider than the 2500 9.5" axle

sooo whats happening?

 

[Overlandtowater]

Nothing at the moment. It’s Christmas shopping time of year. I should be able to pick back up on it after the first of the year.

 

[Overlandtowater]

One tool came in that should make my gear change a little easier

 

[Mekcanix]

oooh Pretty

Get a good inch LB torque wrench, a set up bearing and a nice backlash gauge

Tearing into the heavy half semi float 14 bolt (9.5”) pulled all the drum brake parts off. The 10 bolt backing plate bolts up to the SF14 bolt. The 10 bolt rotors seat all the way on the heavy half axle shafts. Sat the caliper and bracket on the rotor and measured, the backing plate mounts are 2 1/4” to far in on the axle shafts. With the backing plate mounts welded on both sides I don’t want to try and cut them off to slide them towards the outside 2.25”. I was thinking about spacers but didn’t see any online anywhere. I might cut the 10 bolt mounts off and ream them to slide over the 9.5 axle housing.

SF 14 bolt disc brake conversion, first I cut the backing plate mounts off the 10 bolt. To do that I cut the axle housing either side of the mount that way I could take it inside on a work bench, finished by grinding the weld out the rest of the way and driving the tiny piece of housing out with a punch and hammer. Then I needed to ream the inside of the mounting bracket out to slide over the sf14 housing to accomplish this without a lathe I used a metal burr in a die grinder, to keep it slow and consistent I would wipe the surface to be ground down with a sharpie and cut it till the ink was gone. This was slow but seemed to work well. After 4 hours, 15 grindings, one cheap burr, and another abrasive bit I could finally pound the mount over the housing. The easiest way I could figure out how to get the proper depth was to assemble a scrap set of suburban brakes together on the sf14 housing I didn’t have a set of pads to throw in the calipers so for now I haven’t welded anything. I can’t see why this won’t work and no the mounting bracket is not where I intend on welding it. I will pull the 10 bolt out from under the burb and get measurements to copy what is on the 10 bolt. Now one more side to do.
