Lifting for Dummies.... ?

Ok, so I have the 2007 Z71 with LT3 equipment group (I don't know if it matters but it says I have the Rear Axle - 3.73 Ratio)..... I beat the heck out of the bottom of my 2006 and therefore am thinking what I need to do for the '07 is lift it.  At least that sounds logical to me....

What I want:  The bottom of my truck (frame etc) to be higher off the ground... (and I admit to secretly just wanting it to look cooler)

What I need: The Av is still my primary vehicle for everyday driving so I wont be putting huge off road tires or anything on it and would rather not screw up any of the stock functionality of the truck.  (I'm saving my jeep for all of that fun).

The existing tires and wheels are what I'd like to keep, ONLY IF that makes sense.  If not then I'll replace all five with whatever you guys end up telling me I should have. 

Note the truck also needs to remain good for towing a trailer with a Jeep Wrangler Unlimited 4D Sahara on it and the truck will be on dirt roads "easy 4 wheel drive trails" etc...

What I have now are 18" Aluminum Wheels and P265/65R18 BW Bridgestone tires (according to the lil sticker in the window)

Will I need new shocks as well to maintain 'comfort' or will a little lift be fine as-is?

And how the heck do I choose between a 3", 4" and 6" inch lift?  As far as all of the other 'code words' you guys are using when describing your lifts... I'm T-Totally lost.

Any help?

And once I figure out what I want done... any suggestions on where I should go to do it?  The truck is currently scheduled to visit the Chevy dealership service center to have the sunroof installed.  I'm also wanting push bars on it but do not yet know if I should use Chevy for that or go elsewhere....

I'm in Franktown CO (anywhere in the Denver/Colorado Springs area is fine with me... I live dead center between the two major cities)

THANKS A BILLION for the anticipated advice!!! 

- First time wandering away from a stock vehicle....

p.s. I do not have any decent pics of the truck yet but for what it's worth this is it as it sits now....

4" - 6" suspension is typical (also usually seem to end up with similar results.) something to do with advertising.
this will give you ground clearance.

The other option less expensive is a Body Lift.
Dose not add ground clearance. on frame (bumpers and body yes)

Both give you the ability to run larger tire.
giving ground clearance. (to both above SL & BL)

not going to bis a 33" dia tire would be safe and fit stock rims.

I would do my homework on suspension Lifts for a 07 it is still new.
Find some posts of Members that have gone through it 1st.

Best of luck and? :welcome:
Larger OD tires lift the axles off the ground.
to support larger tires one needs to lift the rest.

Body lift semi cheap
Suspension lift semi expensive but allows for more suspension movement
IF money were no object..... what would the preference be?  I'm assuming suspension lift?

You say "to support larger tires one needs to lift the rest." I'm assuming the suspension lift also allows for larger tires?

In the end do both "basically" end up looking the same? E.g. both will lift the body? It's just that one serves to only lift the body (body lift) and one serves to lift the body and allow more suspension movement which is a good thing?  And I'm assuming the recommendation is for larger tires either way right?

I HATE how ignorant I sound but a fact's a fact and I'm ignorant in this area lol (hopefully these basic questions will assist others at some point)

There's a tech from the dealership that's supposed to call me soon concerning my desire to have it lifted and I'd least like to have 'half clue' of what I'm asking for before he starts seeing dollar signs lol

Thanks again!
If money is no object then get both body and suspension lift

Yes suspension lift allows for larger tires...

Body lift can look funky as frame can show more

suspension lift looks "rugged"

Body lift does not do anything for suspension travel it just gives more clearance for larger tires in fender wells

I suggest finding some local members and meeting up with them and see what they have.

also find a few local 4x4 shops and talk to them.  talk to all of them.. get as much in fo as you can
Def plan to but one quick question on your comment....

You say "body lift looks funky and shows frame" and "suspension lift looks rugged"  by getting both does it begin to look nicer overall?  Or does it become funky and rugged looking?
all in the eyes of the beholder....

check out some pics in this section....

tons of them in various threads and you decide
Also next time you are out and about and see A BAD A@@ Ride.
Go ask where they got the work done and If they would recomend a shop.

I asked around at My Preferd; Auto mechanic, Speed shops,and Tire shop.
Found out the tire shop I use dose Lifts love these Guys. American Tire in NJ

Also you are planing on running your stock Gear's 33" (35"s max) for a daily driver
and if you want to tow 33's with no gear swap

Suspension and Body lift lets you run 37's >:D
Your most important concern should be gearing if you're still planning to tow.  That's the issue I have right now, and as much as I hate to do it, I'm going to sell my lifted AV and replace it with a HD.

The reason you'll need taller tires after the lift is it just doesn't look right, not to mention it defeats the purpose of installing a lift, suspension or body.  Once you get taller tires, your performance will suffer without getting your gears swapped out.  Most running a 6" lift end up with 35" tires, and the ideal ratio would be 4.56.  With the hills/mountains you have in CO., you'll need it, especially if you're towing.  I have 3.73's and live in the flat lands where it's not that big of an issue.
:welcome:to the club PicOlio.There are alot of good pointers in here to get the ball rolling for you .My opinion would be to look around in this section look at the topic lifted nation and others.You will get some further ideas from them.Good luck with your decision and let us know how it goes. (y)
Let's see if I can get this to work.....

also, I've heard that with the 07s, the 6" lift doesn't necessarily mean you can fit 35's. So, if you do want to run 35" tires, it might be best to go slightly larger. Also, 33's on a 6" lift are too small and could cause stability issues.
As an FYI, the Rancho 4" and Fabtech 6" lifts I'm looking at (for an '07) both developed thier kits with and recommend a max tire size of 315/70-17" (~12"x34.5"), but still may require minor trimming.

Oddly enough, that size in BFG KOs isn't rated for severe snow. I'm looking at using a 305/65-18 KO? (12.2" wide x 33.7" tall), unless I can find something a hair taller.
"also, I've heard that with the 07s, the 6" lift doesn't necessarily mean you can fit 35's. So, if you do want to run 35" tires, it might be best to go slightly larger. Also, 33's on a 6" lift are too small and could cause stability issues."

I have a 6" procomp lift with stock wheels and 33's, I have no stability issues.  If I replaced tires with 35's, I would add unstrung weight, my brakes would be overloaded, center of gravity 1" higher, more load on steering and suspension parts, and less power.  If lift is designed to handle 35's, 33's will work just fine.
mypackage said:

If lift is designed to use 35's, there should be 35's. When we went to go pick my av up, they had 33's mounted. I asked them what the hell they were doing (in nicer language, of course), and told them to put the 35's on. IMO, 33's are just too small with a 6" lift.
