no I know not "Raise" but the lower you lower the torsion bars the more room the nose has right? and you measure from the bottom of the K frame to right before the wheels are off the ground right?
Yes and no, I never considered the amount of Rise I had but the amount I needed to get the best results. IE 60'times. In my case by use all thread rod where the upper bump stop was I could play with the amount of rise to see what worked the best. In my case about 2" was best.
