After reading the lift information proved on the forum. It says lifting 3" will require a SYE kit and a double cardan u-joint/driveshaft. This might be a dumb question but I'm assuming this is in the rear being that the front driveshaft already has a double cardan u-joint/driveshaft? And correct me if I'm wrong this requires a SYE kit and a custom driveshaft?

Thanks
 
For the short wheelbase TJ it's usually at about the 4" suspension height where a SYE and double-cardan driveshaft is required in the rear. Yes the front is fine, it's the rear where it is needed. I wouldn't spend the $$$ for a SYE/driveshaft for a 3" suspension lift.

What if it creates drive line/vibrations? Just drop the transfer-case skid plate about an 1" ?

Any suspension lift starting at 2" and taller can/will cause vibrations.

For 3" and shorter suspension lifts you can either install a pair of 1" taller motor mount lifts (preferable) or a 1" tcase drop kit to get rid of them. For a 2002 or older you can just stack enough washers around each t-case bolt to drop it 1". For a 2003 or newer you need longer bolts too, they got shorter and smaller in 2003..

Great! Thanks Jerry

Yeah a SYE kit and custom driveshaft seemed like a lot of $$$ to only go up 3 inches.
 
Yep but fortunately you don't need them yet. :)

Ya know I don't mind buying the correct parts and good quality to do a lift and I want to do right one time. It's the labor that beats me up and 4x4 shops charge a truck load of $$$ to install them. I can only do so much mechanically.
 
Rancho makes some very good shocks but suspension lifts? Not so much. I'd go for a brand whose main business is suspension lifts... like Currie, Zone, or Savvy. Other manufacturers like Rough Country or Skyjacker are not top tier choices either

Hey Jerry... What do you think about Rubicon Express suspensions?

Thanks

I had one, their control arm flex joints aren't so good. There are worse suspensions but avoid their long arm suspension which is what I installed. It didn't work all that well and its long arms would get hung up multiple times a day while rock crawling. Their short arm works better. For what it costs I'd pay a little more to go with a Currie or Savvy. Personally I'm now running a Currie 4" suspension lift.

They're just average. Not the best, but far from the worst.

If you want a good lift go with a brand like Currie or Savvy. Zone is a good brand if you're on a budget.

Rokmen also makes some nice stuff as well!

Thanks Jerry... I'm trying to settle on a new suspension to invest in. Plan is to go with a short arm suspension. 33's is all I plan to run here in GA. I want to have confidence on the trail and good manners on the road getting there. PO left me with a budget boost and 35's and other minor stuff to get straighten out. I'm parting out another rusty framed TJ and plan to take those proceeds and roll into a suspension.

Thanks for the response, I enjoy reading your and the other experts feedback.
