You'll want to make sure you're looking at the latest Mopar Lifts. They've been completely re-designed by Mopar where they used to be sourced from TF. All the new Mopar lifts include FOX shocks. The P/N for the 4in lift is 77072353, so you'll want to confirm that P/N matches what you're looking at. The 4in Mopar lift is a very complete kit. It can be found for $1,850.
Here's all the info from the Mopar catalog, it's using cam relocation bolts and replacement Lower control arms for caster correction. It comes in that cool crate as well. I got the Mopar 2in lift since that is plenty for 35's, paid $750. The only reasons to get the 4in is for looks or if you're planning to go to 37's or larger tires.

This statement by Mopar in regards to the driveshaft tends to elude to the kit not being sourced by TF if you read between the lines.

A: When the 3.6 engine was introduced, (2012) the exhaust routing ran the pipe directly under the front driveshaft. When a lift is installed, the driveshaft is lowered, hence it will rub on the exhaust pipe when the suspension drops away from the vehicle. This causes the protective boot on the driveshaft to wear and eventually tear apart, allowing contaminants to leak into the boot and causing the driveshaft slip feature to eventually fail. So far, aftermarket companies have made short spacers to lower the exhaust to fix the problem, but this is untested for emissions and looks like a poor solution. Previously (with the TF kits) we have used a limit strap to prevent the axle from dropping down too far, and while this will work, a flexible suspension ought to be flexible; the limit strap restricts flexibility. We address this problem the best way with a new, smaller diameter shaft, but it is more expensive. The cheaper kits let the driveshaft hit and don't address the issue satisfactorily

I don't believe they are, it's all Mopar from my understanding, aside from the shocks which is obvious. The Fox shocks actual have Mopar branded on them as well. The only additional thing that I see would likely be needed is an adjustable front track bar.

Add an adjustable front from your company of choice and it's a done deal.

If he doesn't want cam bolts, then he would want to get something like the AEV geo correction brackets or adjustable front lower control arms. A Cam bolt eliminator kit is used if you already installed cam bolts, since to install a cam bolt the control arm axle mount needs to be ground/cut. To avoid the grinding/cutting of the bracket you get Geo brackets or longer/adjustable LCA's.
