hey guys i just bought a 2003 xls...im loving this explorer ALOT!! but i have a question for u guys since i am pretty new to this... the ride is kinda stiff and rough when i hit bumps n cracks on the road... how can i ease it up? or have a softer ride? do i change up the springs? if so what brand should i get? and while im doing this i kinda wanna lower the xls a lil bit ...would this be wise? thanks ahead of time for the help guys!
