I am interested in lifting my 2001 Tahoe aprox 2"-4" and looking to do this in the most economical way without having to change driveshaft, brake lines or any major systems if even possible. Does anyone have any experience in doing this to this gen Tahoe and if so do you have pics and info for me. Thank you

 

I've known lots of guys that burn up parts regularly after DIY lifts. These SUV's are practically windsurf boards already... have you considered cramming the largest wheel/tire set-up you can fit in there and calling it a 1/2" lift?
'07 'Burb squeezed 265/70R17's with +38mm offset. Took me awhile to find the right wheel tho...
