New to the site

Hey yall I just recently bought a 2001 Tahoe LS 2wd and I came across this website and it looks like its a pretty good site but anyways Im wanting to lift my Tahoe and I was wondering what is the best and inexpensive way to lift the tahoe to fit 33's or 35's??

You might be able to get away with cranking the keys to at least level the front. That should get you enough room for the 33's I think. I usually go the other way with my rides, so someone else would probably know better than I would.
To fit the 35's you're most likely going to need keys, springs and possibly longer shocks. I think someone makes coil spacers as well, but again I'm not well versed on lifting these things.

Since your 2wd you can go with a spindle lift. They are pretty cheap and can range from 2 to 4in. i would go with a 3in spindle and a 1.5" coil spacer for the rear. A good thing to keep in mind when doing spacers in the rear is that the amount of lift you get is half the size of the spacer. 1.5=3, 1=2, ect.
