why not return the 4600s and buy the 5100s for the lift... and yes you can do almost anything you want, but will it work is another question. i would not run the LC coils with stock shocks,(im not even sure if they would be long enough) the tundra coils... im not sure if you could get away with that one either. but even if you could run both the LC and tundra coils with the shocks you just bought, you would trash those shocks in no time as they are not designed to work in that application
