TJ trying to get a 4" lift

I have an '02 Wrangler Sport and I am trying to get it lifted 4". After doing some research it seems like in order to do that I need to replace the drive-shaft and install a slip yoke eliminator as well. Is this true?

Also I want to get 33" tires after I get the lift. Will I need to get new rims, or can stock rims use bigger tires?

you are correct in your thinking. You might be able to drive with just a lowered t-case skid, but its not the best thing to do. As for 33's depends on the size of your stock rims. Most will allow a 10.50 tire with little rub, for 11.50 and bigger new rims with better back spacing are the way to go. Bs of 3.75 to 4 works well.

Slip yoke eliminators have come way down in price the last couple of years. Rubicons come with them as stock equipment, and I had one installed on a 94 YJ we lifted 3". You can order a custom driveshaft (Tom Woods) or a good mechanic/shop can make one up from a longer one-cut it down, etc. which is what we had done.
I'm running 33" x 12.5" tires on 15" x 8" rims-great sidewall play when air'down. Just check the tire size charts, get the right size for your rim and you'll be all set.
You may 'not' have to change the pitman arm-4" lift kits come with them but it's not always worth changing over...we did change and a month later went back to stock-it lifted the tie rod high enough that it banged against the differential. Switched back, had alignment checked, and haven't had a problem since. Whatever you think you can afford, add $150 or to that and get a better lift-you DO get what you pay for! Less expensive lifts have lousy bushings-get the best you can afford.

I have the Rubicon Express 3.5" lift, which sits at about 4.5" true height, with just a transfer case drop. Absolutely no driveline vibrations on my rig.

Some people get the death wobble, some people don't. I don't know why, but that's just the way it is. If it were me, I'd try the drop first, and if you get the wobble, go for the drive shaft and slip yolk eliminator.

You don't need a SYE with a 4" lift and 33's. I have one and no vib at all and I drive mine as a DD.

I have a 4" lift (Rubicon calls it a 3.5") and right now I don't have a SYE kit installed. It runs just fine, no undue vibrations. I will eventually get a SYE, but it's not necessary with a t-case drop (which the Rubicon lift comes with).

If you don't have the money for the SYE, just put in the T-case drop until you've got the money for the SYE. I've had the drop in mine for over 2yrs without any problems. Sure I'd like to get the SYE and custom driveshaft and regain the clearance but I've got better things to spend my money on.

I have the RE 3.5" SF and dropped the T-Case. I clear 33's perfect and have little vibration. I also added adjustable lower control arms and that helped dial it in well. I ran stock rims with 32x11.50's and they would rub on the control arms when I turned too hard. I recently upgraded to new rims and 33x12.50's and now i don't rub at all with the better backspacing. I would recommend planning on changing your rims as well.
