Does anyone know the length of travel on a 2006 Dyna (Street Bob) rear suspension? I am bolting my saddle bags onto my quick detach backrest struts and don't want the axel bolts to hit the bottom of the bags. It's gotta be less than about 4 inches as that's all the fender to tire clearance there is. But, I want the bags as low as possible. If I can get away with 2 or 3 inches I would rather that. I had the bags as low as I could get them and hit a little dip in the pavement and my bags bottomed out on the axel nut cover, knocking my axel cover off. I could spread the bottom of the bags wider, but that looks dumb. I'm want it all. Tight to the wheel and as low as possible.
