jeep sus. run from $200-$1700 depending on size. like i told him before, his best bet would be about $400. An install on a jeep is fairly easy (granted you know something) so i am sure he could find someone on the side to gladly do it. But yeah, for popular trucks (f-150s, 1500s, etc.) you are looking at over $1000. I priced one for a 99 expedition, and a decent one would run me $2300. FUCK THAT!
