Is there that much flex difference between the two with the the sway bar disconnected? Anyone have flex pics of the super ride with aal?
There's really not going to be much difference in the ride or handling of the two kits because they use the same springs and shocks. The only differences in the kits are the control arms, swaybar endlinks, and bumpstop extensions (the SR kit doesn't come with any).
The SuperFlex kit comes with SuperFlex arms with the articulating joint on the axle end. If you're planning to wheel your XJ, I wouldn't even consider the SuperRide kit. The SR kit comes with SR arms which have rubber bushings on both ends.
This is the kind of misalignment the arms and bushings will have to deal with when you go wheelin' and flex the suspension:
That's why I recommend the SuperFlex kit if you ever plan to wheel your rig.
The SF kit also comes with quick disconnects for the swaybar, whereas the SR kit just comes with extended endlinks. Getting a good set of quick disconnects brand new would cost more than the price difference in the kits, so just with the disconnects alone you're coming out ahead money-wise getting the SF kit.
