I was able to do the CHF on the rear of my 2019 Entegra Vision. However, the biggest bank for my buck came when I did the trac bar to the rear. This will provide more sway control than doing the CHF.
I went with the supersteer trac bar, but there are others. The link below is not necessarily the one for your rig, you need to check the year and the GVWR to make sure you get the right one.
