2 Inch Lift on H2.

[HumminNBoatin']

I am looking to lift my truck. But I dont want a 4inch or 6 inch lift. I just want a little bit of lift. Somewhere around 2 inches. Anyway I have a couple of questions and thought I would post my plan and see what you guys think.

Front End:
Currently the front end is all stock. I was thininking of cranking the T-Bars for another 1 1/2 - 2 inches for height.

But how far is the max I can crank for height before I max it out? I want to be sure that I can leave at least 1 full inch of upward motion if not more before whe arms hit the bump stops

Also how far can i lift without putting too much stress on the CV's and Tierods??? Is an 1 1/2 - 2 inches really going to stress them that much more??

I would also probubly get new shocks as well. I am currently running the original ones so im sure after the adjustment they would be rendered usless pretty quickly??

Back End:
I currently HAVE factory Air ride.

I was thinking I would really like the truck to ride at its extened ride height all the time in the rear with the possibility to raise it yet another 2-3 inches when pressing the ride height button on the dash.

I have some questions about that:
Can I just adjust the height sensors to make it ride higher and trick the computer?? Then press the button and get another 2 inches??
My gut tells me this will not work as the bags will not expand that far.

I was really thinking of placing a hockey puck under the air bag to help with this.

If raising this high, am I staring to change the geometry of the rear end too much. Trailing Arms? Drive Shaft? Brake Lines?

Any insite would be GREATLY APPRECIATED!

When I had my '03 H2, I installed the fabtech 6" kit. It was an excellent product but unfortunately along with a liftkit went bigger tires, different gears and supercharger.

Too much for my daily driver...

Having said that, last week I picked up an '06 SUT. I installed the torsion keys and raised the truck up 2 1/2". With a 2" taller tire, that raised the truck up an add'l 1".

3 - 3 1/2" inches was perfect for what I was looking to accomplish. Here's a pic of before and after.





The best part is the ride.... virtually unchanged.

I just did the Truxxx lift kit on my 08 H2 sut. It is a 2"-3" in front with different keys and shock extenders and in the rear it is 1.25" coil spacers.. Took about an hour and a half to install and am very happy with the kit. It was $315.00 shipped.

Well the hard part for me is the Rear End Lift. I have Air Ride. I want to keep its functionality. I need to find out if there are spacers for the air bags.

I'd like to impart some valuable info to anyone who wants to do the torsion bar lift. IMO it's a waste of money to pay $267 for the <Truxx Torsion Bar Keys> with the shock extender brackets when for $44 ($22 each) you can buy the same keys from <gmparts direct>. Just order GM Part # 15592573.

With the money you save, you can buy quality Bilstein shocks which are longer and do away with the shock extenders. it's a much better way to go IMO.

Here's a photo I took which shows the difference between the OEM stock key on the H2 compared to the GM Part # 15592573.

SummitUp......I agree with you 100%. If all someone is looking to do is crank the t-bars, then the keys you mentioned above from GM and some longer shocks is the way to go.

However, if you want to gain 2-3" of lift, with better articulation, alignment, etc. than I think the kit I mentioned from Cognito is the way to go.

I couldn't agree more. I raised my front end a full 3" to accommodate the 37" KM2's. If the front end is cranked a full 3" and the OEM UCA isn't replaced with the Cognito UCA, the premature contact of the metal to metal bump stop on the OEM UCA's will create a harsh ride as the result. Also the angle of the upper ball joint on the OEM UCA will be too extreme, and will wear out prematurely.

Looks Great Mark! Are those 37" Toyo MT's?

You might also look into the 2-3" cognito lift. I am also looking to go this route.

I not really a fan of the cognito kit. The reality is you can use the OE upper A-Arms and just have it aligned unless you want to push the front end to the max. I am not looking to go all the way with the front end. Just up a little. Also the rear end is where I have more questions than anything. I am going to call Travis over at Rubber Duck as he may know more about what to do in the rear.

"to the max".......that's exactly what I intend to do and run 40"s

Please post up when you find out. I may want to do this as well, and while you are at it run 38s just to make sure i can as well .
