I've heard that different lift kits actually measure at different heights, for instance a TF 3 in lift is more like 4+. What about Full Traction lifts, how do they measure up in this respect? Thanks.

 

From what i understand it depends on the weight of your jeep to deterime the true lift height. If you have 300+ pounds in bumpers, then your jeep will sit slightly lower depending on the amount of additional weight. Also if a 4 inch lift is for a 4 door and a 2 door then the 4 door may get 3 inches of lift because of the additional weight, but some companies like rough country account for the extra weight of the 4 door, so when u order it from RC they ask you if you have the 4 door(unlimited) model so they can upgrade the springs to stiffer/taller ones.

 

Full Traction springs are pretty true to their advertised lift height.

 

I had one of the first TF 3" kits and got about 4.5" of lift. I was told that they have fixed that problem with a larger selection of springs.

 

I installed a Teraflex 2.5" coil spring lift on my four door JK, and measured before and after height. I got exactly 2.5" of lift in front and 2" of lift in back, for whatever that is worth.

 

Just installed the Teraflex BB with shock adapters and got 3" up front and 2.5" in the back on a 4 door.

 

How did you manage to get 3" from a 2.5" spacer?

 

I installed the 2.5 terra flex coil lift in 2 jeep, mine and my girlfriends. I have a 2 door soft top and got 3.40 inches and she has a 2 door hard top and got 3.15. The size on the terraflex lift is minimum of what u get. Same springs go on a 4 or 2 so u get more with 2 door cause of weight. Great lift. Love it. 35s rock climbing and no rubbing anywhere.

 

I was confused too, but after I searched and others had similar experiences. I didnt measure the spacers themselves, but I would assume they are 2.5". I measured from ground to fender before and after install.
