I don't need to take weight off of the rear of my truck. I weight my truck and trailer. Trailer loaded is 5577 lbs and weight my truck only and truck only with weight distribution attached to trailer. The tongue weight with distribution bars attached is 595 lbs. So my guess is the actual tongue weight is a lot more. My weight bars are for 550 lbs max. My truck sits just as I want it too but I do get a little bounce from the trailer. I don't really feel it on my tv thought. I just thought that stronger bars would stiffen the bounce that I'm getting.
