Upper Control Arms Rubi vs Non-Rubi

[lalalofsky]

Are the rubicon and the sport JLU upper control arms the same Size? I was thinking about sending another forum member a message to get the uppers if the Rubicon’s are longer. I have shocks, spring, bumps, sway bar links, and LCAs, off a rubicon that I’m about to install. i also have the steering stabilizer but I’d assuming that is the same between the rubicon and the sport

Edit: I also have both the front and rear track bars from the rubicon as well. Is there benefit in installing those and taking off mine?

All control arms are the same length across all models, including the LCAs. Bump stops are the same. I’m not positive but I’m pretty sure the track bars are the same too.

I thought the rubicon lowers were longer to help with caster

Nup, the Mopar 2" lift LCA are longer but the stock ones are all the same.

So, I will get a small lift from the rubicon take offs, but the LCAs are the same lol. Should I buy the 2” ones. Do you know if with the Mopar 2” lift or any 2” lift for that matter, I’m assumming I’d need new front/rear LCAs, Sway bar link (disconnects), springs, shocks, I have bump stops upper control arms? Both Track bars? or just what’s in the Mopar kit. Lol this stuff has me so back and forth

Install the Rubi springs and shocks (and anything else that is different) and add the mopar LCA (front, no need to change rear) as they are cheap and will sort the caster. Track bars and control arms are the same, not sure on sway bar links and bump stops as I'm in Australia and we get something different again.

Nope, that's why the caster is even worse on Rubicons. What you really want is longer LCAs or shorter uppers. Adjustable is obviously the best way to go.

This is because Rubicon come stock with less caster than Sahara and Sport.

Fully agree with adjustable being the best way to go. It's not just geometry, but also rigidity that greatly benefits the increased tire and lift size.
