Default Question about control arms

I have a 3 inch Zone offroad lift. It rides a little stiff on the road. Will control arms soften the ride a little bit? I am running 33x11.50 Pro comp Xtreme AT and the wheels are pro comp 8128. The combo is heavy. Could that also be the reason it rides a little rough on the road? I love it but want to know if I can make it a little more comfy as it is my daily driver.

Control arms won't change the stiffness of the springs and/or shocks. What psi are you running in your tires?

Goodness! Lower your pressure to about 30 psi and see how the ride is.

the harshness of your ride is being caused by the spring rate of your coils and type of shocks you have. unfortunately, you're stuck with the coils so there isn't a whole lot you can do there but you're running the rebranded generic hydro shocks that come with the kit, swapping them out with a set of rancho 9000's (adjustable), ome or bilsteins should help out a lot.

no. with 33" tires, you really should be running closer to 28-30 psi. that will help smooth out your ride a lot.

The main thing is tire wear. You want to have even tire wear across the entire tread pattern Having to much air will wear the inside of the tread prematurely and to little will wear the outside prematurely. Also to much air will cause a rough ride and sometimes make the steering feel flighty.
