Lift required for 34's on a third Gen.?

I have a full set of Kings,fronts with 650 lbs springs,TC uca and Deavers J66 to install , they been sitting in my garage for about a month due to the lack of free time to install them. The plan was to run 285/70/17 and call it a day but I'm kind of debating going to 285/75/17's instead. I know a lot of people claim that the lost of power by going to 33's is hardly noticeable but experience tells me thats BS and I'm probably going to end up re gearing to restore the lost power and at that point will probably go with a bigger tire anyways . I'm trying to avoid doing things twice. What's the minimum lift required to run 34's , what body parts need to be modified and which suspension parts will you change from the ones I already have? I drive a 6 speed manual
Thanks in advance for any advice

 

Your setup is great. I would recommend getting a CMC aka Cab Mount Chop so you don't have your tires rubbing the body. 2"+ of lift should be good for your 34" Just depends on what you want to do and like down the road. If you're going to gear it 4.56 or 4.88 would be a good choice and bring you back in the powerband for the engine. There's more stuff but it would take a lot of time to explain everything. Check out the stickies in the threads around TW about bigger tires.

 

Taking care of the CMC this weekend before I install lift
