01 MS LS 4x4 , question: is it necessary to remove or replace this with an adjustable one for more than 3" of lift? Does it limit the lift or bind it?
​​​​​​​Thanks.

 

Are you referring to the sway bar? Some of the lift kits come with the sway bar extensions (a little longer connectors). My guess that your old sway bar should work without that in most cases. The only time you may need to disconnect the sway bar is when you do a full on "proper" rock crawling and you want to utilize maximum independent wheel travel.
