Interesting they have it for the 2013 model year, (2005-2013) on the Fox site.
From the looks of the prices on 4x4 parts, and as always, very bad description, seems as if they're about the same price as PRG's set-up, sans the UCA's. ($1040 for front and rear shocks, $780 for fronts only, PRG's are 789$)
But if going with a set-up like this, UCA's seem like a no brainer to take full advantage of the kit as far as wheel travel is concerned.
I'm sure they're adjustable just like PRG's are, since it's a coilover system and looking at the coil over it has threads and a spanner wrench collar and states 0-2".
I would suggest checking out Greg at PRG, very good customer service, and will tailor your set-up for your vehicle needs.

Also, the shocks alone in the rear wont provide the lift, my assumption is that they (the shocks) can support 0-1" of lift, meaning you'd need to pair them with a set of lift springs for a lift.
