The Dixon bros kit is an awesome kit but I wouldn't run it without custom high strength high angle CVs. If you get someone like RCV to build custom shafts to go with the kit, do it!
I'm assuming you're looking at 98+ 4x4? You really need to give some more hints about the truck and what you want to do with it.
The ifs on the 4x4 ranger doesn't leave many options. You can run some specific shocks that will allow a small amount of additional travel (1-2") but require limit straps and of course bump stops. The torsion bars don't flex great anyway. Good shocks go a long way here, as does disconnecting the sway bar. Someone was making a basic coilover setup that could be retrofitted but the ball joints and upper control arms are very limiting anyway. On this platform, QUALITY of travel is often a better focus than quantity in my experience.
An Aussie locker goes along way making up for travel but it sucks in the snow.
For me, as long as I ran a decent shock (bilstein), and did NOT crank up the torsion bars (so the suspension had equal travel in both directions), and disconnected the front sway bar off road it resulted in a very smooth ride off road. Combined with an Aussie locker I always got where I wanted to go. Though in the dunes I was definitely limited to slow speeds in the whoops.
