I just replaced a 2" lift that was on my JKU. I had horrible death wobbles any time I went over 45mph. Tried fixing too many things to list and it never got better. Long story short, I replaced the entire lift with a 4.5" BDS long arm kit. I added the adjustable track arms, quick sway bar disconnects and Fox shocks. I have only had it back a week from the shop and it rides great. No more death wobble. My concern is that now it feels very "twitchy" on the road at higher speeds 40mph+. Almost like when your wheels are pulled side to side when your in a deep rut. It is all I can do to keep inside my own lane on some of the 2 lane highways around here. Im afraid i might jet into oncoming traffic if Im not 100% focused on driving. I did replace the wheels and upgraded to 35" Mickey Thompson Baja MTZ's so they are more aggressive than the 33" tires I had before. Even so, this is the worst handling lifted vehicle I have ever had. I am wondering if the caster or steering geometry could be off somewhere. I am taking it back to the shop that installed it in a week and would like to have an idea of what they should be looking for. Any thoughts would be appreciated. Thanks,
