I know if I go over a 4" lift I should look into getting drive shafts. I love the hight and look of a 4" lift, if I did a 3" BDS lift with a 1" body would I still need to upgrade the drive shafts? I was told I by a local off road shop I wouldn't have to. I plan on doing that setup with 37 open country's and ATX Slabs. If anyone has a similar setup or has any insight on this could you help!
