on toyota trucks when airbagged they dont lay true frame without modification to the frame up front and the tranny cross member. once on the pavement the first thing to touch would be the tranny crossmember because it hangs lower than the rest of the frame. once that crossmember is cut down, or cut out and have a new one mounted to be flush with the frame. the second crossmember to hit the ground before the frame is the front crossmember, its the one that connects the two lower control arms right below the oil pan. in order for that to be moved up so it lays flush with the rest of the frame you have to do whats called a "Z" on the frame which means you cut the frame right before the firewall and and slide everything up an inch or so. it will create something like this ----_____. all of your front suspension is then moved upward. however in doing this your front frame horns will have to drop the same amount so your fenders bodylines, hood, etc all line up correctly with the rest of the truck. your oil pan will also have to be sectioned which is basically cutting off the third hump on your oil pan so it doesnt drag on the ground. stock its fine, but once "z-ed" the oil pan hangs lower than the frame. i prolly went into a little more detail than you wanted but just incase there it is.
