Since adding bigger rims and tires, I noticed that I need some more stopping power. I've searched around and can't find anything on brakes when running more rotational weight. The brake pads need to be changed, and I've read about EBC green or yellow, Hawk LTS and stock GM ceramic pads being the best when running smaller tires. But my question is will those pads be able to stop 37s on 22s? I don't want to spend the $$ on a Wilwood kit. Any help is greatly appreciated

The brake pads are not going to help that much , but it is a good idea to upgrade, I run the Hawk pads, You might also look into changing the rubber brake lines and adding Stainless Steel Braided lines, that will also help a little. Stainless Steel Brakes Company makes kits for the Chevy / GMC trucks, and not that hard on the wallet.

The brake lines were changed when it was lifted. I forgot to mention that. What are you running for brake system?

Have you tried to engage the ABS? I would be willing to bet that you can still engage the ABS, which means technically you have enough braking power to over power the tires. The brake pedal will still feel stiff as hell and give you the impression that you're not stopping well.

To improve braking feel you need to either increase the friction at the pad with one of the pads you listed or increase your brake hydraulic ratio. You increase the ratio by either calipers with bigger pistons or a master cylinder with a smaller piston. You'll get a longer pedal but more "power". It'll feel like your pedal drops lower before the you get to the "friction point" as I call it, but once there you'll have more pedal feel.

The problem you'll have is that with the stock size rotors you'll still fade the brakes just as easy as before maybe even quicker since you have more braking power. Only fix for this is bigger rotors or brake ducting, but it doesn't sound like fade is your problem.

Mmcall will be along shortly to tell you to check your stock brake hardware for binding. He's right as just about all of these trucks have problems with this issue.

I have the SSBC Calipers ( Front ) and Slotted Rotors ( All ), At the time Brembo brakes were my only other option but was not spending $ 6000.00 for front calipers and Rotor's, so went with SSBC. I would like to get the WilWoods, the only set that would work is the Hummer H2 setup with a little fabricating for the 3500 Dually. Good Luck

37's on 22's will never stop well with factory brakes lol. Your wheel and tire combo and stock brakes are like a 5,000 pound load to your brake system with no weight in the truck! The rotating mass has a huge contribution to the handling and breaking of your truck. Ricer set ups will not do well off road either. Set these truck up like trucks. JMO! lol
