JBA Upper A-arms for lifted jeeps

So I got my RC 2 inch lift in, my question is, is it a must to change a upper control arm with a JBA Upper A-arms for lifted jeeps, I have seen some pictures of what happened to some jeeps that have not got it replaced when they did a 2 inch lift and up, itís funny that a $169 lift kit can cost me an extra $450 I guess thatís the jeep bug that we all have

Yes, you need the JBA upper control arms. I just got some. When I first put my Rough Country 2" lift on I didn't have a bad angle on the ball joint but now it has gotten worse. I'm not going to take a chance as it's not worth it. I'd rather spend the $450 because it's a lot cheaper than having your wheel fall off.

I simply replaced the UCA ball joint only with a greasable MOOG problem solver bj when I installed my lift. It is a little stronger then the OEM one and AFAIK does not max out range of motion. I have had no trouble with it for 50k miles.


That being said There are also adjustable BJ's that are around $100 a piece that are designed for a lift and allow for extra range of motion. That could be another lower budget solution as well.

I will go with this option if my MOOG BJ starts showing signs of wear.

I disagree that aftermarket A arms are absolutely necessary for this particular instance. However running the original stock ball joints that are likely already worn out with a lift and beating them up offroad seems like a recipe for disaster.

What about original ball joints that have only 52,000miles on them and very mild off-roading (dirt roads, sometimes)?

I just left the XK to change the tires and re-align, so I'd rather not have to go back to the shop very soon.

You should be fine for awhile. If you were over 100k id say change it now.

Mine were worn out at 95k when i installed the lift.

The lift puts an unnatural angle on the ball joint and causes constant pressure on it. I have seen too many photos of broken OEM ball joints with wheels and tires laying on the ground. Personally, I feel safer having the upgraded a-arms, but to each his own.

I guess this why I go with the flow and drive a non lifted XK.

That's no doubt the cheapest option

So like four then?


It's extremely uncommon.
