I have the exact same like RK 3.5 with rubicon shocks, I run 38psi off trail 18 psi on trail. I have 17" rims, what is your rim size? I would assume that makes a difference if you have 20" that would give you a harder ride.
If you dont mind me asking what determins the load, I see you guys used d,c etc.
My ride isnt bad on streets, I will eventually go to a better shock. maybe a fox?
