Anyone have any clue what the height difference expected between the TF 3" and the 4", I currently run the TF 3" BUT NEED MORE LIFT next set of rubbers. Any help would be great.........

 

an inch,,,,,

 

M.O.R.E. 1'' BL

 

The TF 3in sits around 3.5-4in depending on the weight you have added up front and on the rear.
The 4in kit sits at 5-6in. Also depending on 2dr or 4dr.

I have the 4in TF flexarm and LOVE it.
It is sitting at about 5.5in. I can easily fit 37's with full stuff and cut fenders. 40's would be tight, but your CG would be great. You would have to have cut fenders or aftermarket high fenders. Along with your 1in body lift, you should be set for 40's.

HERE is a link if you want to see the weight I run on it. (Scroll down)

 

they say the 4 inch is a 5.25 lift

My 4" started out about 5.25. I am sure that it is closer to 4.5 nowadays. Bumpers, winches, skid plates and other goodies have added a lot of weight. It has also been wheeled about a dozen times since then. I installed it last Labor Day weekend.

Still plenty of room for 37s now that the front fendars have been trimmed.

 

Thanx for the input, I got alot more than 3" with the 3" lift hope I get the same outcome from the 4", the 1" m.o.r.e. 1" bl helped a little but I think ima just swap out my coils to make up for the bigger tires,bumpers, winch, etc.

 

Those of you running the 3" and 4" teraflex lifts, did you have to do anything to your t-case i.e. lowering kit. How bout longer cv drive shafts? Are they a must? If not do you have any vibration issues? Also guessing you replaced control arms and track bars. These damn jeeps start getting expensive rather quickly.

 

AK- I currently run the tf3" with 35's with plenty of room for 37's, that also with a ton of added weight from my bumpers and winch, I have no vib. issues I'm planning on swaping out my 3" coils to the 4" just cuz i can, I dont plan on new drive shafts just yet, not till i need them anyway. Oh and I have swaped out my lower arms just for better handling. Slowly but surely I plan on installing the 6" TF long arm kit one day.....Till then, keep rockin

 

T-case does not need lowering as the TJ's did, it's a different set up.
