Pick whatever 2” or 2.5” springs you’d like. The general consensus for shocks and a cheap price and good ride is rancho 5000x or blackmax from skyjacker.
I’ve run the RC springs with Rancho shocks and liked the ride. OME also has some customizability in spring rates depending on your intended use for the Jeep
You can go with virtually any steering stabilizer you want as well. I’ve ran OME, ZONE, RC and FOX and thought they were all fairly similar minus the FOX and RC. Fox seems to push my steering wheel and the RC seals wore out too quickly. If you’re steering is setup correctly a stabilizer won’t do much.
At that lift you’ll likely get vibes do to the rear driveshaft angle. The easiest and cheapest way to fix them will be to add some washers between the frame and skid plate (lowering it) until the vibrations go away.
Hope it helps!
