OME Nitrocharger PLUS vs. 5100 with ??? Springs

Hello, All

2011 DC Rock Warrior 4x4, 200K. I was under the truck the other day and noticed that the rear shocks are leaking, time for replacement. I also discovered to my horror that the front shocks are the originals... Here's what I currently have:

The truck currently has a 2" front spacers & 1/5" rear blocks. The rear blocks will stay but the front spacers will go in the trash. Stock coils/shocks & stock leaf springs. The front coils are going to get replaced as well, it leans to the driver side. 285/70-17 tires. I could put it to stock, but my wife wants to keep the level/lift

I'm a believer in buying parts for 90% of what the truck does. In my case, it's a daily and the remaining 10% is forest service roads in the rocky mountains. Right now the truck rides like doo-doo IMHO, both on and off-road. I'm mostly interested in on-road comfort. Off road performance isn't a huge concern, but I'm shopping for a lift, so it does matter.

I would like to hear from those that have the newer OME Nitrocharger Plus kit. This is appealing to me because it comes with springs (PN 4017), front struts (PN 93018), and rear shocks (PN 63100). I can also get them assembled for $100 and shimmed to correct the lean. It's all designed to work together. There's lots of info on the older Nitrocharger Sport struts and 612, 613, 614 springs, but not much on the new setup.

I'm also interested in 5100's all around but from what I've read they are best used with the stock springs, and I won't be reusing them. The other option is to use OME 612 springs, but those already have a lift and even at the lowest perch it would exceed the upper limits of the 5100. The question then becomes, what spring to use?

Also open to other options. Given that it's a 200k mile truck, I'm not interested in spending big money on suspension. Thank you!
