Hi Guys I was in a store the other day & the RHINO REP was there, showing their new racking systems for JK's, apparently they had made all of the "cast die's" for out4x4 but are now doing there own at 1/2 the $$$.
they are called the Rhino Backbone & you can get them from any accessory shop that sells Rhino Products (Auto Barn, ARB, Oppisite Lock, Iron Man stores, TJM,s ect ect) I have had the out4x4 version on my car now for years, & its probably one of the best mods I have done.
cant find the OZ site but this will give you an idea.
