lift based off of which springs??

So here's a weird question...and maybe it doesn't make a difference. Say u were getting the AEV 2.5" lift. Is this 2.5" based off a rubicon or a sport....

Cause we all know that putting in a higher spring rate (say 19/59 out of a rubi) can get u an inch or so of lift on a sport.

So how is this figured??

Thanks

Bryce

On a lift like AEV it'll be 2.5 inches above stock after you add bumpers and a winch. If its stock you will probably get 3 or just over. As for the spring rates...rubicons don't automatically get the stiffest springs. A lot of factors come into play like whether or not it has a hard top or a tow package

I'd guess it's 2.5" above the average springs. Somewhere in the middle rather than an extreme

I think it's just 2.5 bigger than the springs that are in it. While the Rubi springs may be stiffer, I don't think they are physically taller than the Sport springs.

I just took my Rubi springs out and replaced them with a "2.5" lift. The front was 2.5" longer than the Rubi fronts and 2" longer than the rears. When I took them out of my TJ Sport years back it was the same thing....

Most lifts are gonna give you more than what it says on the box. I think kjeeper10 got something like 3" out of his 2.5" TF lift. I ended up with over 3" on my Full Traction setup, even with heavy-ass bumpers and other weighty mods.

Over time, the springs will usually settle a little bit, too.

I have wondered the same thing. If you check the specs on Jeep's site the Sahara and Rubicon are listed to have (respectively) 1.4" and 1.5" more clearance than the sport model.

The Sport S, Sahara, and Rubicon all come with 32" tires.

I don't believe there is a difference in spring height but they are different rates from a rubi to a sport.

That's why people take the ones out of a rubi and put them in a sport. Cause u do gain a bit of lift.

But as for tire size...they're both 32" tires but the actual diameter is about 1/4" difference. That's why if u go buy a rear tire cover they have 2 different part numbers. One for the sports mad Sahara. One for the rubi.

And the sport and Sahara have the same tires which doesn't make sense as to why the Sahara and rubi sit higher than a sport....it has to be in the suspension.

With different spring rates, you get height increases because of the spring firmness and they do not sag as much.

If you have stiffer springs they aren't taller then the weaker ones but you do have more lift with the stiffer springs because they don't compress as much with the weight of the vehicle.

Saying that, people will see a little more lift with replacement coils on weaker stock springs then those with stiffer ones. Probably not much though. The reason is, they put the stiffer springs on Jeeps that need them due to weight. Stiffer springs are usually on Unlimited models. If anything, if people want to call the stiffer springs anything, they should call them Unlimited springs instead of Rubi springs but even then they seem to be random.

But yes, you will see a little better lift on a 2dr with weak springs then a 4dr with stiff springs. Main reason many manufactures list their springs as an example 3" 2dr/2.5" 4dr. And thats because of the weight and spring rate from each. You will see many post all the time that they only got 2.5" with their 3" coils while the next person says they got 3.5" out of the same set of springs. I all depends on 2/4 dr and stock spring rate alone with mods like heavy bumpers and winches.

Another question along the same line - if you got the tf 2.5 Bb lift with springs, how do those springs compare in stiffness to the stock jk ones? Would they be more like the softer or mor like the stiffer?

The tf bb uses the stock springs, so there us no change in stiffness. They're just mounted with 2.5 inch spacers.

There is. 2.5 coil lift as well. How about the coils in that kit?
