My understanding is that this is beneficial for the older F53 chassis coaches. Not sure about a new one. Handling difference -- with ours it previously seemed that you had to constantly correct the steering and couldn't go straight down the road. Also when semi's went past it about blew you off the road. It was 2 hands on the wheel and never a moment of easy driving. Now, semi's don't blow you over and steering can be a one hand affair with all the constant back and forth to keep it on the road. We had already tried new tires - front end alignment and put a steering stabalizer on. This adjustment made a world of difference and DH said he wished he would of known about it 3 years ago when we started driving all over.
