I have a 2006 GMC 1500HD which I tow my Jayflght 28BHBE, I am installing new torsion keys to rise the front of my truck 1-2". I have coil over rear springs so the rear sits higher than normal. Would I have to adjusted my tow hitch squat bar set up thanks.
All TV suspensions react differently...., after installing the suspension risers I would take your TV/TT combination under loaded conditions to a CAT scale to confirm your WDH settings.
Also, keep in mind that WDH's are designed specifically to distribute weight, not level the TV. Rear TV squat of 1"-2" is a normal occurrence with a properly adjusted WDH.
