Ladder bar w/floater or Caltracs

I would either run what you have, or go four link at this point. If you're pulling the wheels a foot and simply carrying them for 10-20 feet you dont need bars. If it's hanging them for 60', you should ge teh 4 link and you'll need bars...lol. The instant center on a leaf car is pretty much non adjustable, except for the front end rise and ride height. On a 4link you can adjust it where you need it and you will go faster. If you are contemplating ladder bars, go 4link. They are so similar in install that it doesnt make sense IMO to replace leafs with leafs, or go ladder keeping the leafs which is simply adding weight and nothing else to the package.
