Default Replacement springs & shocks

I have a '17 JKU Sport that I bought used in late '17. The previous owner put the ~3" lift with 35x12.50's on, it looks to be all Rough Country.
I bought it for mostly street use and some mild trails.
The steering seems pretty normal for a lifted Jeep, I've had several prior to this one.
The problem is, I moved to Wisconsin and the roads around here are crap and the ride is really rough.
I'm looking for any recommendations.
I don't want to completely start over, so maybe just new springs & shocks??

Thanks in advance,
Jim

People are going to recommend rancho adjustable shocks. Also, in my experience, airing down the tires helps. I run my stock size tires around 32 psi.

Yup, shocks are going to have the biggest impact, and something that is adjustable is going to offer at least a range to play with vs. non-adjustable after market options which are commonly on the stiff side.

You mention having lifted jeeps before, so presume you're not just saying that the steering is "normal", as in shitty, but chalking it up to just being a lifted jeep. Do you know what the caster angle is at right now? Have you measured for actual lift height netted? Does that lift have a drop pitman arm installed (since you think it's a RC lift)?

Steering has a little bump steer, nothing violent. Tracks nice and straight on a good road. I can take my hand off the wheel at 70 on the freeway with just slight road crown drift.
I run 28 psi in the Toyo Open Country tires, any higher pressure and the ride gets worse. There are bumps on my daily route that will get both rear tires off the ground. On a cold day that is pretty jarring....

Y, if you're running one of the "E" rated Open Countrys, that's sure not helping your cause. Dang stiff side wall.

That's interesting, I didn't realize they made 2 different load/speed ratings in the same size tire for some sizes. Looks like both the 33x12.5 and the 35x12.5 come in 2 different flavors when it comes to 20" wheels. Odd.

Mine are the Open Country R/T ...but they have 2 versions of that one too.
I've tried dropping the pressure down lower than the 28 I run now, but really didn't notice any improvement.
The last oil change I had done they aired them up to 35 when I wasn't watching....interesting ride home to correct it.
