X2 to the Rancho RS5000x. I'd replace all four at once, not just the fronts. The rears are easy too, you don't need to jack the Jeep up to replace them. Just give the rear shock's upper bolts 3-4 days of spraying them with Liquid Wrench, Kroil, or Break-Free. Don't waste your $$$ or time spraying the bolts with PB-Blaster or WD-40, neither of which are effective at loosening hardware that might be seized from corrosion from salt on the roads.
