Do NOT get the "OTT" lift..
there are a couple of vendors out there that sell this one..
It is the full 2.5" lift..
It tears your Liberty apart..
If money is a concern, get the RockyRoadOutfitters
COMBO lift.. (2 1/4") .. this one is 199.00
If money is not a concern, get the DayStar COMBO lift.. (2")
this one is about 325.00
I have had my RRO COMBO lift on for over 1 1/2 years now and have had NO problems with it..
I have not heard of anyone having problems with it..
Or as Clint mentioned, you can spend a LOT more money if you want..
