front suspension on the NBS trucks is fairly simple because the front suspension has very nice geometry stock. the key tire diameter is ~29". As long as you stay around this number or below it, you can keep the control arm mounting points stock without excessive tire wear from your camber curve (the amount of camber change you have throughout travel). On a 29" tire, you can get the alignment low enough that your camber won't be much at all laid out.
by far the cheapest setup that is good
McG 16+, shortened lowers, flipped uppers, and upper cups.
If you want to spend the money on aftermarket arms then MMW, ART, and KP are about the only options anymore because of the option above.
I would not waste the money unless you really wanted aftermarket arms
the easiest rear setup is by far the Ridetech air bar. The kit is 100% bolt on. Only ting necessary to make the kit lay is having a bigger notch welded in and moving to top bag bracket bar moved up higher. the F9000 sleeve bags ride awesome (these are what my new setup will have). this would be perfect for a truck like yours and with a tire size you have, the panhard bar is perfectly fine.
$1700 and comes with the bracket for the carry bearing for a 2 piece driveshaft, shocks, bags, and bolt in c notch(i'm sure you could sell).
I know it's $300 more than the KP kit, but it's far less work and if you ever decide to get rid of the truck, you can put the stock suspension back underneath it and keep the air ride.
Trying to make this as simple as possible for building a truck without a welder
Ridetech Airbar-$1700
Cup kit with bags-$300
We already talked about Accuair prices.
that will actually put you on air without needing a welder. grinder, sawzall, drill, wrenchs, etc.. garage tools is all that's needed.
your only fab work will be what it takes to lay. tranny crossmember, 2 piece driveshaft, bigger notch, gas tank crossmembers and tubbing. all of which can be done later down the rode when time or money allows unless the budget allows for it now, since you're only in $2000 on actual suspension pieces.
