If you are looking for a Heavy Duty bag that can ride ultra smooth and out tow whatever you truck can handle, but are focusing on a low ride height such as a 2wd or dually truck, this firestone bag could be your best choice, but certainly not limited to that. Completely compressed on its safe internal bump stop it's only 4.5" tall. Almost 10" (9-5/8) of working travel. Will last for many years and 100's of thousands of miles on a semi truck so if you install it correctly with no rubbing it will be ultra reliable.
