JK suspensions

Hey Guys,

What are the differences between the normal and the performance suspensions that are listed for the JK. I've been looking at a loaded 09 X and the Rubicon. Dealer wasn't able to answer the question.

Idk if you meant the axles and stuff when you said suspension, but I think the only difference the Rubicon has from the X is basically that it has D44's front and rear, lockers, 4:1 transfer case, swaybar disconnects, and 4:10 gears.

Idk i could be missing sruff

All these different springs are there for a reason. I just looked into the parts catalog and noticed close to 20 different part numbers... Why.. May be it is related to wheelbase, vehicle weight load per axle... I am sure they all have different spring rates and free length.. This combined with axle load will define spring frequency..
I wonder why...might it be to control DW...
