Really????

I have the Rancho lift with factory wheels...no problems...

This subject is really peaking my interest. First of all I did not realize the "knuckle" kits space the front wheels out even wider than stock. Then the drop bracket kits seem to just move everything downward.

I was leaning toward using new torsion bar keyways and the cognito UCA's to gain a couple of inches and more downward travel.

From my experience, it's all about down travel, and mose IFS trucks (ours) has very little. That is the drawback to the Cognito plan, by raising it, I am also loosing down travel, so I guess that is not a good option either.

Finally I noticed Cognito offers a 4-5" drop bracket system for 2500 GM trucks, but not for the H2. Hmmm... the H2 is very similiar to the Suburban which comes in a 2500 also.

Now, about the Rough Country, Factory wheels can be used? Did I read that correctly? And without spacers?

he Cognito 2500Hd kit does fit the H2, it's just not in the H2 section . However, if you look at the kit for 2500Hd it does say Hummer H2.

It also allows more downward travel by relocating the stop, provider cushion on the stop, and puts it in factory alignmnet specs all at the same time!

SWEEEEEET!!

OK, so it's looking like the the cognito 4", the superlift 6", or still the near stock height option with the cognito upper arms. I want a little lift, but for me it's all about travel, especially in the front. I know how to make rear axles travel: Relocated shock bracketry with LT shocks, control army with something like Rubicon express joints, lengthened brake line and wiring, and maybe a driveshaft mod.

Over the years, I have learned for a standard track truck a ratio of about 70% travel in the rear and 30% in the front, keeps the rollovers to a minimum.
Shocks (and suspensions seem to work best with 3"-4" of stuff, and the rest of the travel all in drop out.

But with all the track of this thing, you could afford to stretch the front some without worrying about terra based aerobatics.

I emailed Cognito on this question.
Their response stated that the 4"-6" 2500HD kit does not fit the Hummer. They did not go on to explain why, only that it would not fit.

So, I'm looking for a kit that allows the use of the stock wheels that wll give me 4" to 6" of lift and increased wheel travel. I think, no matter which kit I get, I will add the cognito UCA's and wort with the poly travel limiters to gain max down travel with the added lift.

I see that one member with a RC uses stock wheels, although the Rough Country web site says the wheels will not fit, hmmm. Superlift will work but is more costly and uses a bunch of brackets, and lowers the Torsion bars (into harms way). I'm also wondering which kits require another front driveshaft. Bought those before , and they get spendy pretty quick!

No problem.
I will, however, add that UCA to whatever kit I buy. That way I get both increased gound clearance amd increased travel. From what I can see, all these lift kits do is just what the name says. They do not increase suspension travel which is FAR more important. All you could do is safely get into a little deeper water with just a lift kit.

Our main goal should be to get the "tallest" tire we can fit in there without rubbing. Wider tires are nice for increased traction, but can limit flex/travel when you get into a situation where they hit the outer fender etc. I don't care much for a 6" lift - just to go up another 1/2" or so in tire size and at the same time raises the center of gravity

Personally, I am just going to tweak the stock setup as far as it will go to keep the factory warranty and get 37s underneath
