I'm looking to get a 3" BL and run 35's probably about 12.5-13.5" wide (or something close to that). I don't know what size wheels to run or what BS for the least amount of rubbing or none at all. Also, I have no idea what keys and bars are that I've seen mentioned while I was skimming through the threads. Are they things I will need to look at for my setup? And one more thing, what about cranking? I'm assuming that means the torsion bar but I'm not positive and if so, should I be thinking about that?
So basically I'm a noob looking some guidance on how to make the setup I want work.
Thanks,
Matt

35s you will need at least a 4 inch lift if you decide on wheels that are 4.5 inchs of backspace. most aftermarket wheels are. the prefect combo would be 315/70/17 tire on a wheel with 5.5 in backspace. Your stock wheels are close to that but i would not recommend putting that wide of a tire on your 6.5 wide wheel.

solution: you can crank the t-bars to get around 1.5-2 inches of lift. just make sure at the end of the crank you still have a fingers width between the upper control arm bump stop and the frame or your ride will suffer greatly. alot of guys including myself are t-bar cranked and running h2 rims on 35/12.5s. The h2 wheels have 5.5 inches of backspacing so it tucks them nice. You will however have to trim the inner fender wells.

if your dead set on some aftermarket wheels try to find some that are around 5.5 inches of backspace. anything less you will have to cut metal without a lift. As for your body lift, im personally not a big fan of them, but many guys on here with half tons run them.

here are some pics of my 2500hd on h2s and 35s

hope that helps you out some

Cedric, he has an HD dude, he doesn't need four inches of lift just to run 35's
Go to this thread:

I posted pictures of how my HD used to look. This is just cranked stock bars and new shocks. I fit 35's on an 8.5" wide wheel with 5.5" backspacing and with some minor trimming never rubbed at all.

Now everyone is gonna have a different story on cranking and stuffing, every truck seems to have a different story.

the only cranking you should be doing is inside your house

i understand he has an HD so do i. i was saying he would need to run a 4 inch lift if he wants to run an aftermarket wheel which most have a 4.5 in backspace. With a 5.5 bs wheel as you mentioned in the other post, all you need to do is crank and trim such as i did with my h2s.

You can get plenty of wheels with 5.5 backspace, my current wheels have that backspace as well. There was a member on here, I think its twotones brother who runs the same setup just cranked with a 16x10 wheel and 4.5" bs on 315's and he does fine to

Dont do a body lift on a hd, they look really really big the frame hangs out alot. Do a level kit or something, just my 2 cents.

i see, i was just letting him know what my personal experiences were. i didnt want to tell him about a 4.5 bs wheel since i have had a few friends that have had to do quite alot of trimming and just ended up lifting, didnt want to give him bad info. 5.5 bs does seem to be the best fit though. got any pics of the truck with the 16x10 and 4.5 bs? seems quite wide and i think it would stick out quite a bit. i doubt he could fit those on there without a bl or timming the metal.

oh _nar_ im know them from dieselplace.com, nar had to do a shit load of metal trimming to the fender. just something to remember when you get the wheels. a wheel with 5.5 in of bs you wont need to trim the metal from the fender, just the bumper valance and the inner fender.

Thanks alot for the input so far guys.
2LoNoma: what setup do you have on your GMC? That looks a lot like what I'm looking for. I have the crew cab too so it gives me a really good idea of what it'll look like.

He's got a suspension lift, so that's significantly more $$$ than a BL.

Oh, alright. Damn. Ok, well I've been reading some more posts and I've been hearing about this 4" Cognito lift. Anyone have any pics of that? Is it any good? I'm assuming I could easily slide 35's under that since it's possible with only a 3" BL? Maybe 36's?

Evan

The 4" cog really isn't worth it because you can get the 7-9" for a couple hundred more, I know that you still save money but you WILL want those extra inches sooner or later and will end up spending more money getting a new kit than if you just get the 7-9"

BTW- Cogs are pretty high priced anyway

Yea I just looked at the price of the Cognito...$1600, then I saw a 3" kit from Performance Accessories...$365
I think I'll go with something like that and settle for 35's with some possible cutting...
That's outrageous for a BL.

The cognito is suspension.

Ooooh ok. Well I don't need that then. I'm just looking to fit bigger tires under without rubbing or too much cutting.
