Unfortunately, there are a lot of jackasses in this thread giving bad advice.

Most kits are marketed as a 4", 6",etc and you can crank further.

For instance, the Rancho 4" kit can be cranked further. The fabtech lift only drops the full differential 4.5" and you can crank another 1.5-2" on top of that. The procomp lift is full 6" drop lift and you can crank on top of that(although not recommended).

With that said, do you realize how cheap it is to lift the back of our trucks? Granted if you go to new leaf springs that can get expensive, but you're talking about less than $100 to go as high as 6" higher over stock.

Getting new torsion keys is NOT doing it right. New keys are basically re-marketed Ford keys which are just indexed differently so you can crank more. In reality, buying new keys is actually worse for your suspension as you can run into more trouble with cranking.

Now with your NNBS silverado all this stuff gets thrown out. The new trucks don't have a torsion system so there is no "cranking"

What your point? When people say lift kits they mostly mean the front because thats the part that matters. There are a 100 ways to lift the rear. You just ranted on nothing. B

If you want good info on the GMT900(not NNBS) GMFullsize has quite a few members over there with lifted GMT900s. They were very helpful in making my decision

My point exactly. This is what I meant, or should I say how I meant to say it. Lift kits that quote a 4-6" or 6-8" lift mean just that, what you said. You get a 4" or a 6" kit, and can crank the torsions to get another 2" in the FRONT.

I won't agree with you there, about the "troubles" and all. UNLESS, you are talking about cranking the new keys up so much you get the front way up there. Then you can come into some vibration problems, and CV shaft problems, brake line problems, allignment problems. Then yes, you will run into problems. BUT, if you just want to "level" the truck as I did, you will not run into any problems what so ever. In fact, my truck rides just as nice with the torsions cranked for level that friends don't believe that I have cranked the keys a little to get it level.

But now he was talking about adding the "leveling kit" to the "lift kit" so he can clear the 35's?? That is doing the same as "cranking" the keys on the torsion IFS systems. There he is going to be putting spacers in to bring the allready 6" lifted front up another 2". So does that mean he is going to go with 8" lift blocks in the rear to make the truck sit level? Bad Idea in my book.

I wasn't trying to rant. And I am sorry if that was the way it sounded. But you are wrong, when people talk lift kits, they mean the whole truck. Leveling kits are where they talk about the front. At least all the people I talk to do.
And yah, there are quite a bit of ways to raise the rear of the truck. But I will take a new leaf pack over 6" blocks any day of the week. Reason being, lift blocks SUCK. You get more axle wrap, more vibrations, and poor performance from the rear of the truck. AND, there was a guy on here who was in a rear end collision and his lift blocks/u-bolts broke, and twisted the axle under the truck! You wouldn't get that with a new leaf pack.

No advice given is actually bad, the bad part about it is that some people listen and take that and actually do it.

And if anyone believes that my advice is bad. Then so be it, I was stating as Hero has, but I guess it looks as though I can't put it into words like he can, or maybe it is because he has more posts than I do. But what I was saying is pretty much what Hero just wrote here.

So let me apologize now that if anyone followed any advice I have given here and it turned up to be "bad". I AM SORRY!!!

One other small fact. Did you guys know the reason for the "nose down" look on todays IFS trucks? It is because all the manufacturers making the 1/2 ton trucks make the trucks with this stance. This is so when you put the max load in the bed of the truck, your headlights will not blind people when you are driving at night??
Got that little bit of info from a GM tech rep at a CORR race one year back in the 90's. And if you look at all STOCK 1/2 ton trucks they are ALL "nose down" from the factory, whether they are 2wd or 4wd.

I will agree on you on most of your last comment. But on this I must say you are wrong. I got hit when my truck was stock and it broke the stock u bolts and bent the springs. I don't like lift blocks thats for sure thats why I didn't put them in. Well the 5 in one anyway. And when i get more money I will put 4" springs in.
