As everyone stated above ^^
your wallet and your usage of your truck will dictate which route to take.
Neither are wrong or right. It just depends on the 2 factors. How much you want to spend and what you will use your truck for.
Many members do not off road here and we throw the option of level and body lift and you can achieve anywhere from 3"-5.5" depending on combinations.
5.5" of this route is taller than most actual lift kits with the exception of RCX which is 5.5" as well
Bilsteins (2.75) and 1.25" body lift will run you $350 shipped for 4" of lift
4" RCX full suspension lift will run you $1250 shipped
Both are plus installation, but quite a few here install themselves to save on labor.
Again, its all it what you do with your truck, dollars you want to spend.
Let me know if there is anything I can assist with
