I fi have a 2 door but dont have the cash to lay down for a whole set and have a 3 inch lift should i jsut get front lowers and rear uppers for now? And my lift is actualy about 2 3/4 its not a full 3 inches. I heard front lowers for handling and rear uppers for the stock driveshaft ona 2 door. Thanks

 

I'm not sure if you actually need the front lowers with only 2 3/4 in. but they will help dial in your caster. The rear uppers will allow you to set your pinion angle.

 

I am just under 3 inches on mine and have over 25k miles on it. No need for rears, I am going to get lower fronts at some point in time but it drives good just the way it is.

 

After reading numerous posts on the same subject, I came up with the same conclusion as you. Front lowers will help adjust your castor with a reasonable lift, and rear uppers will help with your pinion angle. Larger lifts will require more adjustment to attain the proper castor and pinion and thats where the other control arms come in to play.
I went ahead and ordered a complete set of Currie uppers and lowers for the front and rear for a couple reasons:
1. David at Northridge has numerous in stock and he is cutting some sweet deals on them!
2. By installing all of them now, when I want to go taller, which we all will at some point, all I will need is larger coils. Spend more money now, less later.
3. Currie's, with Johnny Joints in both ends are supposed to be the best out there, with a proven service life of over 100K miles.
4. Aftermarket control arms just look cool!

 

Im planning on doing the same thing, ordering the control arms with the double johnny joints. I am only running the rough country 2.5 inch progressive coils.

I had a YJ with coils up front and I had welded in the johnny joints on both ends of my control arms, and i ended up having a ton of flex, it just flopped around like a slinky. it was awesome. johnny joints are definitely the way to go, they are a pain to assemble with a press, but once they are put together they are amazing!!!

 

When I installed the rear upper and lower FT arms with my JE Reel 1350 driveshaft I was amazed at the improvement in rear end feel both on road and off.
I say do 'em all!
