Checkout Fabtech, they started out specializing in 2wd suspensions. ifYou can pick up an issue of Dusty Times, it will give you a lot of manufacturers that build products just for the offroad racers. As far as 2wd chase truck goes, invest in a locking diff, soft, long travel suspension and medium wide tires to let you float the sand and dust pits and it will work just fine. have fun Barney
