Yup still TTB, and no it's just factory raidus arms. What shocks would you guys use for this? It needs new shocks BADLEY. and i'll try to get some flex shocks today.
The stock arms are what's killing your flex. And I bet some of the harsh ride you are experience is from the worn out shocks not controlling the excess vibrations.
For now I'd suggest any name brand shock: Skyjacker, Tuff Country, Monroe, Rough Country, Pro-Comp, Fabtech ect ect. Every lift kit manufacturer has a shock listing for lifted Rangers and to be honest most are made by the same company or are extremely similar. I also did not list them all, there are tons to be had. In addition to that, each brand usually can be had in either gas charged or hydro versions. Gas charged being the better variant. These kinds of shocks should run you no more than about $35-$40 a peice.
If you want to spend more look into Bilsteins (HD replacements or 5125's)...They run about $75 a piece (I think they are worth the extra coin). I have them on all four corners of my truck and love 'em.
Course then there is RadFlo, Icon, Fox, King and many other super expensive brands....no need for those really unless you just have more money than sense.
I'd measure for what size shock you need, then consult this list (it will tell you how to measure as well):

And later when you want to work on fixing the limited flex, go make your self a set of longer radius arms (many have done it, its not too bad if you have fab skillz) or James Duff, and Skyjacker both make a great set of aftermarket long arms for your application.
