Long arms move the wheel & axle more vertically and along a flatter arc.
With 6" lift or more, this is meaningful.
Up to 4" lift, there's no noticeable change in ride feel.
I compared 2 similar Jeeps with similar 4" lifts, one had long arms. None of us -- the other Jeep owner, a 4x4 shop owner and I -- could feel a true difference.

This sketch illustrates the difference, and why a true difference exist only when the lift is over a certain height:

 

I'm running Monroe Reflex Monotubes on my 2-door Sahara. It's light -- basically all factory.

At first I thought the shocks were firm, but after about a year of driving on them I think they're now on the softer side of things. Kind of hard to say, because they're digressive. I do know when swapping from the hard top to the soft top the ride tightens up and improves for me. I have about 40-50K on the shocks.

I really only do on-road driving, but on really lousy pavement. Handles it all pretty well. My wifes ride is a 3-series BMW - so I'm not comparing the Jeep to say, a F350 If anything I'm probably being a little critical.

 

Am I correct in seeing that the long arm kit would be less squirrely on road because the arms would be more parallel or level?

 

Read post 41... Up to 4" lift you won't feel a difference.

 

Fox IFP 2.0 (smooth body shock). They are half the price of the fox 2.0 reservoir.and will perform just as well

X2 on the 2.0 IFP's. love mine.

 

Rancho 9000 or fox 2.0 ifp?

 

If you are going with the fox 2.0's. make sure they are the TF or BDS tuned shocks. I've read from venders that their valving works great with a JK.
