I bought AAL, they failed after a couple of years... as everyone said they would.
I bought my OME springs from Southeast Overland in South Carolina, I am running them with Bilstein 5100s. I am heavy front and rear. ARB with winch up front, Oztent rv4 up top in a thule box, camper shell with 2nd batter and ARB fridge. By the time I add water, food, camping supplies I feel like I need the HD rear, and even unloaded with the extra weight that is permanent the HD seems to be a good fit.
