Suspension Kit Recommendation

Currently running the rough country 2.5 leveling kit and after 4 years the rear shock took a crap on me. I think it's time to get a new setup, my first two options were fox 2.5 and icon stage 4/5. Been calling everywhere and unfortunately for me they are backorder for 10-12 weeks, do yall have any recommendation for any other kits or should I wait? I have looked at bilstein 6112/5160 setup as a 4th or 5th option also but they are also sold out

What I want:
2-3" lift
budget 3500
light off roading, mostly highway and looking for a comfortable drive
riding on 35 atm
would need shim or shackle for any of the recommended setup

 

Falcon with Coachbuilder shackles. No need to spend $3500 for your usage.

 

I figure 3500 would be overkill for mostly on highway driving. I figure buy it nice or buy it twice. For 2-3” lift would I need + 2 or 3 shackles?

 

Made by Elka, good stuff.

Trd pro replacement

 

That is a good option also, I gave them a call and they gave me 2-3weeks back order for the toytec kit which is way better than 10-12. Really considering that kit now.
