2.5 inch susp. lift with 31" or 4 inch susp. lift with 33"?

hello everyone,

I drive a 2005 stock Wrangler 4.0lt, with Rubicon tires (245/75/16). I am thinking of upgrading it, but I have some doubts about what should I choose. 2.5 inch suspension lift with 31" tires, or 4 inch suspension lift with 33" tires? What is your opinion? What about cost? A 4 inch S/L will need more parts to be changed? If I'll install a 4 inch S/L with my tires (245/75/16), I will look like a fool?

it depends on multiple things:
Is it your daily driver? Do you want it to continue to be ?Will it be used for any off roading?

Also.. What rear axle do you have? You will either have the more common Dana 35 with 3.07, 3.73 gearing or possibly a Dana 44 with 3.73 or 4.10 gearing.

This will be a factor in determine your tire size.

Note: you don't need a exactly a 4" suspension lift...

Once you get around 4" of suspension lift things may get pricey. You may want to consider a combination of a 3" Suspension lift, and a 1" Body lift or similarly, a 2.5 inch suspension lift with 1.25 body lift. The body lift won't effect the suspension of the vehicle at all and will allow you to stay out of the real pricey area.

As far as using stock tires on a 4" lift yes it will look goofy.

So really you need to give us more info to determine exactly what you should get.

what about 2.5" suspension lift with 33s? (requires 1" bumpstop extensions in front, 1.5" in rear, and a 1" body lift). Thats what I'm running.

Most 4" suspension lifts will require 2" bumpstop extensions to prevent the shocks from bottoming out. Make sure to get a kit that includes these.

I drive this car only on weekends and holidays. Since I use it for my free time, I go off-roading most of the times (snow, mud, beach, trail), but I also drive for an hour or two in the highway. I am not an extreme off roading driver.

To tell you the truth I don't know which Dana do I have, but I am willing to change to 4.56, if I'll go on 33s.

At the time, I am about to put a new, more bulky tank of LPG, in the place of the current gasoline tank. This tank will go a bit lower from the current one (an inch or 2) and I don't want to be anxious about its safety when I drive…

2.5" with 33s looks very cool, but, as far as I have read, there occurs a lot of rubbing…

Perhaps the solution of 3 + 1 is the best one (or 2.5+1.5).

I am reading all day to find the best solution for me… Up to know, I've seen that 2.5 inch is very low-cost, since I'll not need to change more parts in my car, that I'll have to change when I'll ger higher (even with 3+1). Is that correct?

The economical way to run 33s is with a 2" suspension lift + a 1.25" body lift. Any taller than 2" will most likely net you driveline vibrations, which will require additional upgrades (i.e. SYE, DC driveshaft and adjustable rear upper control arms) to resolve.

If by unfortunate chance you do get vibes from a small 2" lift, it can easily be resolved by installing a motor mount lift (preferred) or by dropping your transfer case with a spacer (you'll lose underbody clearance). In any case, both methods are less costly compared to the SYE route.

then your reading stuff by people that don't know wtf they're doing. add bumpstops and wider flares and you're fine. rubbing the flares isn't a problem, you need to worry about the actual steel. bumpstopping properly is important.

33's and a 2" lift no problem on my 99 TJ. BUT: My wheels have only 3" of backspace.

As I understand, the factory wheel has about 5" of backspace. That would make mine rub.

so your answer is ...it depends.
