Help How Do i upgrade My 04 f350 suspension to 450

[mar666.0]

Just wondering how and if its possible to swap a 350 suspension for a 450,,,i need more beef in my suspension i currently have to replace balljoints every year and my current suspension cant handle heavy loads,,,,lift kits arent an option and airbags dry rot with the winter conditions and living by the ocean,,,what can i do other than buy a duallly?

you can put the 450 springs on the back but the ride is gonna be real hard, you could probably change the front leafs out for the 450 springs too, but I am not 100% sure on that part..I do know it will ride horrible with 450 springs.

Is your truck a 2WD or 4WD? If it's 2WD I wouldn't even bother since the 2WD F450's and F550's have a straight axle. You have a SRW. F450 axle is gonna look wierd on that that.

Got to a local shop and have them made.... I would personally get air bags. Given your situation and them cracking custom made would be the key. If you find a competen shop they should be able to get you set up.

Have you tried a spring shop for trucks. I did this with a 97 Dodge and they added 2 leafs to each side and it helped a lot.

not sure if they can but I would call either alcan or deaver and see if they can make you some custom springs.

I think the 450 has a wider front axle but I dont know if it would affect anything by just using pieces.
