Since you have a jeep lifted higher than usual and want information about making it a better ride, you will find a lot of conflicting opinions. I would suggest reaching out directly to folks in your terrain area and asking them for information about kit that works. Many on here will try and steer you in one direction and that is usually that long arms have no purpose.
Just for shits and giggles, here's a photo of long arms being used effectively in a manner that most folks on this forum would scoff at. Jeepspeed!
I've had a discussion with some on here before that said that length of arms aren't a factor in the photo below and that this same build can be achieved with shorter arms and correct shock valving. To that, i say good luck.

But there's not much left of the actual Jeep there. Look into the rear well, and it's basically almost trophy truck... There is zero inside cab left behind the front seats, and I'd almost venture to say there's nothing really "Jeep" from the cowl back on the body... even the door areas are not close to factory.
