2000 4x4 add a leaf help
Just bought a 2000 4x4 with the 4.0 in it for our ranch and need some advice. I put a flat bed on it and when it's heavily loaded the back end sags pretty bad. Whats a good company that make an add a leaf for this year model? Or throw me another suggestion for supporting the rear if you got one. Thanks in advance for the help.
