2005 jeep grand cherokee suspension

[audioque Sam]

Hey guys,

I have a 2005 Jeep Grand Cherokee limited 4.7L. With my new upgrades i have too much weight in the back and need to do something with my stock suspension. I really would like to bag my jeep but its a 4x4 AWD, and i heard it was harder/more expensive to bag a 4x4 AWD. I don't know much myself about suspensions or what all I'd need to upgrade it to where it can sustain the weight in the back.

This is whats in the back to give you guys some idea about the weight

(3) SQ HDC 3.0 15"s

(2) XS Power D3100's

(1) AQ 3500.1d

14cubic ft. wall glassed/supports,double baffle

multiple runs of 0awg and all other needed wiring

(1) kenwood XR400.4

60 sq. ft. of deadening

preferably i'm looking into bags with adjustable ride height. or any other suspension that will help the ride height/support.

if anyone could find me a good bag kit or any type of suspension that will relieve my problem would be appreciated or any advice. thanks
