I dune with +2 +1 LSR arms with Works double rates, +4 G Force Axle (just bought this), and a +6 CFM swinger with a TCS rear shock (just bought this).
Still working on my motor, but I thought I'd throw out some names I use.
I had the +2 +1 arms and Works shocks on there before the build and it rode like a champ. I've been riding desert for a long time, and love the woops... I'm a big guy, and this set up works great for me.
