8" and 35's do I really need gears?
I got a 05 2wd with 8" of lift and 35's and I cant even get a chirp out of my tires nether less burn out, and I can feel a lack of power. Is it about time to re-gear?
I hardly ever go hardcore off roading and most likely will go upgrade to 37's and a BL sooner rather than later.
If it is the case I would like to go Yukon. What ratio would best fit my set-up and where is a good place to get them?
Thanks guys and Merry Xmas:santa:

I have a few questions:
1). What motor is in your truck?
2). What gear ratio do you currently have?
3). What do you plan to do with your truck?
I personally have an '06 4x4 with a 6" lift, 35" tires and 3.55 gears. After I lifted the truck and stepped up to the 35's I felt a loss of power compared to the stock, and I know that my torque converter is working overtime trying to get me up to speed, but otherwise it hasn't been too bad. I don't do a great deal of towing, but when I do tow I make sure to keep the transmission out of OD and keep the torque converter locked up. If you are only occasionally towing, then you may be able to put off a re-gear for a little while, though frequent towing and stepping up to 37's might justify a gear swap sooner.
I will be re-gearing with 4.88s in my truck, but only because I rarely drive on the freeway, spend a lot of time in the hills and plan on going with 37s in the future. Most people are happy with 4.10s or 4.56s and 35" tires. Since you have a 2wd truck, you could get by with 4.30s in the axle (they do not make 4.30 gears for a 8.8" IFS axle, not that your 2wd truck has to worry about that). If you are certainly going to move up to 37's, then I would select the 4.56 or 4.88 gears depending on your driving style and planned usage for the truck. If it is a 4.6L, then I would almost certainly install 4.88s to give the truck all the help it can get. Hopefully that helps out a little bit.
One last thing: I've been lifted on 35's and 3.55's for the last 30k miles, and in that time I have towed up to 7,500 pounds in 102 degree California heat with no ill effects.

My engines a 5.4L
Its my everyday driver, I live in Miami and work about 15 miles away so its pretty much all highway. And for what I want to do, the most extreme would be the BL and 37's.
I also don't want to completely kill my gas mileage.
Man, I cannot find the label on my diff that would tell me the gearing. Is there another way?

Inside of your door is a sticker with a bunch of information on it, look for where it says Axle on that decal, and then find the 2 digit code associated with it. After you know your axle code, post it here and I will tell you what it means.
As an example:
My truck is axle 19, that is a 3.55 open differentials
My friend's truck is axle H9, that is a 3.55 with a limited slip

yeah with 38s but running 35s and 4.88s rpms will run a little high wont they?
