This may have been covered before, but as you can see by my post count, I am fairly new to the Jeep game. Would some one please explain how a long arm kit works, and who really needs them in what envirorment? Thanks

unlike the old TJ which had really short control arms, the JK has arms that are considerably longer and really, work fine up to about 4" of lift. the reason why you'd want long arms is that at about 4" of lift or more, the geometry of your control arms will be off enough that among other things, your ride quality ON PAVEMENT will be effected negatively. in order to install long arms, you will need to cut off your factory control arm mounting brackets and have new ones installed to allow for the longer arms and, once you do this, your geometry will be restored closer to stock thus greatly improving your ride. again, you will notice this mostly ON PAVEMENT.

As you raise a JK, the more the axle end of the control arms is pointing at the ground. The sharper the angle the more the ride quality suffers. With long arms the frame mounting points are moved inwards, which improves the riding quality and handling on/off road.
