Hey, I have been reading alot in Peterson's Offroad about rigs having a 4 link suspension put on them. I have an idea of how they work but could use some more experience. Can anyone provide further guidance? Has anyone ever done one and on what vehicles are they mostly applied too?? What are the cost involved in relation to SAS and IFS suspension lifts and applications?? Are there any pics of such a conversion to be found that show what it looks like? Thanks so much.
