Bigger calipers with hydroboost would put your retinas on the windshield!
I love my hydroboost in the diesel. I'm putting it in my gasser too.

Today I wore my WF T-shirt. My 5yo says "It's the Suburban that's missing a wheel!"
--pause, while intently examining the brush guard--
"Daddy, you should put a thing on the front of our Suburban to push the trees out of the way. Like this one, or like the ArmyTruck!"

I could feel the difference when I went from the 37s to some very heavy 38s and the H2s with wheel spacers. It got slightly better with the 40s on KMCs, but it’s not tight.It’s not a huge leap to say factory square body brakes are, well, underwhelming. That’s before any fun parts or beef get added
Yessir. Brackets are from Torq.So you get the caliper from Powerstop and the bracket from someone else?
I’m not sure what kind of booster and master cylinder tuning might be required, but you’ve got the same idea as me.Bigger calipers with hydroboost would put your retinas on the windshield!
You’re training the next generation of diesel suburban aficionados.Suffice it to say that your truck has become famous in my household.

No. This uses the matching the Dodge rotors, which are also large (I’ll layout the whole kit tomorrow). I have to machine the hubs so they slip over. This only works inside a 17” wheel.Same rotors as factory?
GotchyaNo. This uses the matching the Dodge calipers, which by are also large. I have to machine the hubs so they slip over. This only works over a 17” wheel.

So these are remanufactured or brand new castings? You happen to have a part number?They’re Powerstop’s version of a 2009 Dodge 3500 caliper. They have minor rigidity improvements over the stock ones, plus a fancy powder coat.

That's really good feedback, and thank you. I still have the 3/4 ton piece on the truck, but have been planning to use that 34mm/1-5/16" bore size master for this change, since I just don't see how the smaller bore can push enough to make the Dodge calipers work. Arguably, I should have switched long ago.I'm not sure what master cylinder you are running but i have a P30 hydroboost/diesel and 4 wheel disc one on my diesel blazer and it increased the stopping power a ton. Bolts right on and increased the bore size from 30 mm to 34 mm if remember correctly. Might need the extra fluid flow with those bigger calipers.
Brand new from Powerstop: KC5411-36 is the fully loaded kit. I put it in my Amazon store: https://amzn.to/2WRJwijSo these are remanufactured or brand new castings? You happen to have a part number?
I thought by '07 they were using the AAM rear axles?
Yeah Dodge runs the 10.5 in lighter duty early common rail trucks and then switched to the 11.5 I was not sure what GM ran in what trucks as far as 10.5 vs 11.52001 is when they made the switch to aam.
I have a '03 aam axle in my 79. It's the 11.5 ring gear. But they still make the 10.5 ring gear for some applications. I assume this is a 11.5 otherwise I am not sure the point of the upgrade? Unless your after the fact-tree disks.
