Keeping the cost down.
I can't afford all of the fancy air ride so to make my F250 ride better I went with Sulastic Shackles for when I am running empty or a light load. Tried air bags to handle a heavy load. They blewout within 1 1/2 years. No more air bags, I now use Sumosprings for the heavy loads. I Sumosprings do not do anything when I am running light but engage when I drop the Montana on.
