2005 Axle Swap

No. Only f450/f550 with 4.56 or steeper gears have the super 60. F250/f350 have regular 60 as well as f450/f550 with 4.30 or shallower gears

Ok. Thanks for that info.

Easiest way to tell is by where your coil springs sit. If they sit on a perch on the knuckle, you have a regular 60. If they have a separate perch on the tube not part of the knuckle, you have a super 60!

Did you just line the rear spring hanger mount up with the top of the frame and bolt it in? Trying to figure out how I will do that and keep it close to the same. I have to use the SD hangers because mine are rotted out like yours were.

The rear hangers I kept at the same height as the old ones, and the same center as the old ones. I would measure it off the donor truck first because I think I should have moved the rear hangers back 2" due to the longer spring. If you run the rear hanger you may as well run tge front one and then you will have to use SD springs.

Have you removed the front hangers yet off the old frame

Everything is still on the 06 frame. Going to pick it up from storage this weekend. I am picking up a fifth wheel tomorrow and don't trust these hangers more than this one load. So the swap needs to get done!

Ok, that's why I did it. Needed new ones and figured why buy them when I have a set. Take measurements b4 you take anything off!

Did your truck already have overload springs on it? Mine did not. But the 06 springs do. My frame has holes for them though. The back ones had the same bolt pattern but the front ones don't.

Did your factory pads line up correctly?

Also did you use the factory trac bar or an adjustable one?

You must use OBS overloads as the SD ones are arched differently and will rest on the pads all the time.

I have an adj track bar

Gotchya. Looks like those are going to have to come out when I find some OBS ones. How much capacity do the overloads actually add?

What track bar did you go with?

They will have to come out before it rides down the road. Otherwise the overloads will be restong on the pads all the time, even unloaded.

I have the old style pure performance trak bar

I don't have pads on there. There was none from the factory.

Frank as far as installing the front diff did you just take static measurements? How did you locate the front diff this is my biggest concern doing this swap. Also if mr Lott could chime in on the SD box swap that would be great.

Frank and I both have the SD steering box. Bolt in with the exception of honing out the homes in the frame for the larger bolts. I already had a hydraboost, so my lines had the right fittings. Otherwise you'll need some new ones.

Very cool project. Has anyone ever swapped 05 axles into a 99-04? Would it be worth it?

Ralph, you got my number now, just text me you have any questions.

As for 99-04 trucks, yes. Its a bolt in deal as far as I know. I think all the holes are already in the frame

I am wondering the same thing as OBSsledpuller, how did you locate the front diff perfectly, and is the SD Gearbox needed ? Is there an advantage to using it over the stock gear box?? What else am I going to have to buy to make the 08 f350 suspension work?? Thanks
