2 Inch Lift on H2.

[OrangeCrush]

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.

SummitUP,

To get the full 2-3" from the Cognito kit, does one need to purchase the green keys also or can this amount of lift be had from the full crank of the stock t-bars?

Thanks for the input in advance,

That's a good question Duck, and I would say it all depends. In my case I needed the "green keys" to get the lift I needed. The adjusting bolt on the driver's side only had a 1/4" of adjustment left before bottoming out (passenger side was at 1/2"), and turning it in all the way didn't give enough lift.

My advice to anyone wanting to do this is just go ahead and start cranking the T-bars up and see how far you can go. There's a tremendous amount of pressure on those adjusting bolts, and to avoid damaging the bolts (i.e. stripping the threads) it's highly advised to unload the front suspension first by jacking the front end high enough to get the front wheels off the ground. And don't forget the WD40!

One other thing to consider, is the torsion bar key installation tool is required to change the keys. Looks like this:

So, there are three options on that page.

Two are $460 and one is $680.00. I would think it would be better to use the extended length shocks over the added brackets as well.

So what is needed if you are going to raise the front end up 3".

maybe a full list with part#'s would allow us to order all teh correct parts at once.

Maybe we can list this out as FRONT and REAR parts added/modded.

I the past i turned the tbars up just a little, added fabtec tie rods and rancho shocks/steering stabilizer....but the shocks would blow out up front quickly....too short.

This time i want to add to the height (without doing another Rancho 4" kit), add to the steering support, idler/pivot support, and increase what little travel we can get up there.

So, what do I need?

Here's what I have so far:

FRONT:
Rancho steering stabilzer $55 RS5407
Fabtech tierods $245 FTS71002
GM green keys (3" lift to the front) $44 15592573
Cognito Idler Pivot Kit $200 IPAWG8
Cognito Pitman/Idler Support $216 PISK2008
Cognito Upper Control Arm Kit (someone please fill in all that is needed)
Shocks (not sure, I would like to go extended length without adding purchases)(does fox make the proper extended length)

Rear:
Samco rear Springs (1" of lift) $360 SCH2Rear Spring
Crown Brake Lines (+2 length) $159 CR-H2
Shocks (not sure on shocks needed) (fox maybe)
rear spring spacers (not sure if these would be needed after adding the samco springs or not)

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

[DuckTruck]

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.

[DuckTruck]

"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 .
