Weight distribution chains stretched too tight?

When I used the EaZLift I had it on the 5th link. I would jack the trauck and the trailer up together until it was hig enough to get it on the 5th link then let them down and the chains would have mega tension on them. Made the truck and trailer pretty level and gave a smooth ride. Only problem was the sway. had to get the hensley arrow to get rid of the darn sway.
