MarkJ has really good points. SinewStew, your suspension is sagged and height-wise your Jeep is not where it was when it left the factory.
To gain back proper suspension travel and get your Liberty back to stock height - maybe just a touch more - go with OME or Ironman springs and shocks from
JeepinByAl.com. The link is to a full set of Ironman springs and shocks that will run you around $800 and will give you essentially a new ride. Will your Liberty be "lifted" with those springs? Yes - but only lifted back to factory height. What you'll notice immediately is better handling on the road due to the fact your Jeep isn't bottoming out the springs over larger bumps, railroad tracks, etc. Will the center of gravity be higher? Yes, since it is now raised back to where Jeep designed it.
The "lifts" you see on this site are the result of new springs along with extras that add height to the Jeep. Certainly not necessary for what you want to do with yours on the Outer Banks - but you will definitely gain comfort and stability with OME or Ironman springs & shocks. I'd stay away from Rusty's Off Road as their springs sag quickly and you'll be right back where you are now in short order.
I purchased my new suspension over time - bought front springs this month, rear shocks next month, rear springs the following month, front shocks last. Spread the expense out over time to suit my budget but I got a very high quality suspension that gave me the flexibility (pun intended!) to build the Jeep I wanted.
Keep us posted :waytogo:
P.S. Long-timers here, JBA has now officially changed the name of the site from JeepinByAl to JBAOffroad.com.
