H2 Hummer wheels fit with just spinning torsion bars?

Jay, just do some trimming, then lower it as much as practical. Keys do not help the ride stiffness at all. The stiffness is a result of reducing wheel downtravel. Pogo. A longer shock or shock extension will help quite a bit.

im new to the forum, but I put 265/70/17 Nitto Dura Grapplers on my H2 wheels and I haven't experienced and rubbing onmy 2004 2500HD crew cab.

i got a set of 315/75 toyos on my truck with a superlift 6 inch kit (kit for sale cheap, only got 25k miles on it) and i could maybe fit something a little bigger with it! if i were you, if you want the tires, you would be better off with the lift! i'm converting my truck to solid axle and goin for 44s so i'm sellin absolutley everything from under the front end!

The thing you need to understand is what does "fit" mean? What top your suspension out and trim ...."Fit"?

Jay Carnes, Look at this and you will see what you need to look for to maintain your ride and find your best scenario :

After you crank your bars up you start to loose rebound/drop out travel.



When you turn your keys up you limit the travel first with your factory shock. Easy fix with extenders or longer shocks.




After the shock you loose drop out travel between the UCA and frame stop. A bad ride at that point, metal to metal. You also get a bad factory ball joint angle that binds and will wear out fast. Also the factory UCA does not allow for correct alignment spec. most of the time.





Turning your bars up are the number 1 upgrade GM owners do to get a little bigger tire under there trucks. So Cognito looked at the problems that occur and came up with there Cognito 2-3 leveling UCA kit. The bases is to correct ball joint angle and alignment specs. When testing there set up they found that the factory CV shafts will allow for alittle more drop out than factory allows. So when you find that the stance you get after cranking your bars is where you want your truck to sit and your ride has gone bad then you have ran out of drop out travel, the Cognito UCA will give you 2" more drop out from there to gain your ride back.








Again does the Cognito UCA kit give you lift? No, it corrects the problems that occur when you level your truck with factory UCA.

- For guys that are drag racing using 4wd and sled pullers, this kit is not for you because the CV angles are greater than you can use at that torq. when in 4wd. A 4" lift with a drop front diff. will work better since you will have level CV angles not cranked up.

- Guys that are every day drivers and regular 4wd offroading, this kit is great for you to get bigger tires under the truck for a better look.

- This kit works best with Bil5100's front and back.
- You can add a rear 1" block and u-bolt to raise the rear as well.




Hope this helps....
