i have a 05 f150 4 door with a 6" suspension lift with air lift 1000 bags on the rear....i'm having problems pulling heavy trailers is there anyway i can put 250 or 350 rear leaf springs on my 150? and if i upgrade the rear should i upgrade the front coil springs or just leave them alone?

thanks in advance

Try overload springs or helper springs before you try putting in f250 springs. They are designed for a much heavier truck and as such will reaaaaally decrease your ride quality and might possibly be too stiff to be safe. If you already have a 6 inch lift on the truck you don't need to upgrade your front springs. Just got to stop the back from drooping with a load on it.
