Those lower link bars are not gonna bend, look how beef those things are, thats not a fbi 4 link. What I am concerned about that is your uppper bag mounts with no proper bracing on the top, those will bend over time, regardless of what amount of psi you put to them.
Granted this picture im showing you of this truck is a all around hack. But you can see were the upper plate was starting to fold upwords.
Just lookin out for ya buddy.
