I have a between a 2" and 3" lift, probably around 3". Would a terraflex 4" quick disco work ok? Still using factory swaybar

 

Oh ya, should be just fine. You just don't want to be smaller if anything, that not good.

 

I used the 0-3" Terra disconnect on My OME lift, which is about the same height you say that yours is. The sway Bar sits perfectly level with that combo.

 

2 posts, 2 different answers. Gotta love it!

Call David at Northridge, or Teraflex! They both know a lot more than I do!

 

It is what it is...

 

Not really two different answers. He asked if the 4"ones will be ok and I figure sure with 3"s of lift. If you can get the 0-3" ones even better.
Once lifted you just don't want to be using shorter ones ie. like reusing the stock ones, way to much risk of potentially inverting your sway bar should you be connected and droop low enough to have it reverse once everything comes back down, or up so to speek...if you can picture that...not good. Going a little taller shouldn't bother much providing if your connected you don't smash anything when fully compressed.
Hope this helps.
