I have a 2018 (so not the live valve) and just did the fronts with 70K miles.
I researched a couple of online advertisers that rebuild (hammer was one, texas off road was another) and after shipping, etc. it was around $500 for the pair of fronts (like $900 for all 4), and found a local shop that rebuilds Fox and Kings for $400 per pair. The killer for me was the wait time, from 3 weeks to 2 months, and that's me taking off mine to have rebuilt and being out that time.
I went ahead and bought a complete pair new with Geiser 2.5" coils and did it my self. All of the shock parts with new dust boots, top hats, nuts came in just about $950 for parts, the springs were another $599. I had a local tire/suspension shop install the springs for $125 (I tried 2 different compressors, the old school outside jaws were dangerously flexing, the cage style was bending before I could get the Geisers even close to fitting).
Install from start to finish after springs on was just under 3 hours....that's changing truck/jeep around putting on jack stands, tool prep and clean up. Best quote I got from a shop to do it with me providing all the parts was $600.
I did consider Fox 3.0s, but the best price for the fronts alone was $2700, so after everything with new OE/Geisers I am into it $1,624 for complete front setup and parts.
