I've been battling rear end sag for quite some time. A couple people at HIH8 had mentioned a set of ARB springs that might fix this issue. Right now I'm running the Slee HD springs that Christo suggested. They just can't seem to hold the weight. I'm wondering if the OME 863 I think was sugggested is any better? Anyone have experience? I'm running a set of ARB drawers and fridge in the back along with an ARB dual tire carrier rear bumper.
