If you are looking at rough country I would suggest the 3.75" vs the. 3.25". The shocks are a bit harsh, so just buy opt out on the shocks and buy some skyjacker, or bds hydro's. If you have a heavier rig, or plan to add a winch, and or armor then avoid rough country. Their spring rates are very low and don't support additional weight very well.
I would also look at zone offroad. The 4.25" kit is a very nice entry level kit.
I am looking for a comfortable riding lift not too rough. If I need to go 4" I will but I'd like to stay a bit smaller. I checked out the zone off-road lifts. I like them but I need to know if they are stiff or soft suspension. I have a limited budget so I can't make it rain at 23 years old
The zone lift has a soft riding hydro shock. The 4.25" is a combination lift that uses a 3" suspension and 1.25" body lift. I would suggest replacing your stock control arms with new stock control arms. Most aftermarket arms are crap and not as good as stock. The control arms that are worth buying use a real Johnny joint at both ends. The metalcloak duroflex bushing control arms are also making a good name for them selves.
I bought the 4.25 and only installed the 3in lift and am running 31s currently. I think its great! I did go with the nitro shocks and its a little hard but Its not my DD and I like it for the trails. I plan on going 35s soon (well when funds allow) so at the point ill be throwing on the BL/MML
I think the true test of anything is - would you buy it again? YES 100%
