Kind of a dumb question but how do i know if i have it? I have a '91 Ls400,If anyone could help id greatly appreciate it

 

Down by the shifter you would see buttons to adjust suspension from normal to sport, as well as an air suspension button. If you don't see them,, you don't have it. Other way is to look in the wheel well to see if you have shock/spring combo, or what looks to be an air bag.

 

ok thanks man!
