I think we need to start a stick post at the top of the screen to cover the questions we see everyday (what lift kit, 2wd->4wd, sas blah blah)..

I'll start out by giving the obvious

4x2 to 4x4 swaps

80-96 2wd F-150s -> direct swap to 4wd using a Dana 44TTB from a 80-96 4x4 F-150 or Bronco

80-97 2wd F-250/350 -> direct swap with F-150 Dana 44TTB, however that is with front 5 lug hubs. Also able to swap an '85.5-97 F-350 Dana 60 using Offroad Unlimited or Sky Manufacturing shackle reversal kit, or making your own front shackles.

99+ 2wd Superduties -> direct swap using 4wd Superduty parts

SAS swaps:

80-96 4x4 F-150s&Broncos -> relatively easy swap using a 78-79 F150/Bronco Dana 44 & radius arms. Have to use 78-79 radius brackets, coil buckets, 5" or higher lift springs (to avoid cutting engine crossmember) and relocate the radius arm brackets futher back on the fame. The only real fab work is to make a good track bar bracket. You can use the factory 78-79 track bar or a fancy adjustable one. Note that the fabtech SAS kit will work, but it way overpriced for what you get (roughly $2000 + axle).

80-97 4x4 F-250s & 80-85.5 F-350s -> bolt on swap, use 85.5-97 F-350 Dana 60. the 85.5-91 Dana 60 is prefered as it has kingpins for extra strength. You should use the F-350 pitarm and tierods/draglink; however, the F250 inverted Y IFS steering will work, although it is sloppy.

Bronco2&Ranger SAS -> You need a 73-77 F-150 Dana 44, but a lot of fab work is required.

any body else wanna add? Maybe we can get ryan or carlene to make this a sticky post if one of them drops in...

 

Great idea...e-mail Ryan and see if he can make this a sticky

 

On the bronco2's and rangers though, the 9 inch and 44 out of a 66 threw 77 is alot easier because they have the spring buckets in the same location, and I think they might even be the same width

 

Yup, 73-77 F150 is definatley not the right choice.
Early Bronco axles are as close to a bolt in them as a 78/9 F150 axle is in an 80-96 F150

 

ok, it is EB front axle with the Ranger. A guy on blacklist has a 73-77 in his bronco2, but it is a definately a little wider..

any other trucks, what about a Dana 60 into a 78-79?

and I guess a 78-79 Dana 60 will bolt on any 73-79 F250?

 

You can put a fullwidth D44 under a ranger/BII if you use the upper coil buckets that match the 44. It makes it nearly a bolt in.

what about a 73-77 F-150 Dana44? What is the big difference between them and the 78-70 44s? I have a line on a 3.50 geared 77 f-150 front...

I know the coilbuckets on the 78-79 are cast on the drivers side.. other than that?

 

The only difference is that until 77.5 the perches are welded and after that they are cast into the tube. With the cast perches, no tube passes through the C wedge which makes them a pain to narrow, practically have to retube the whole axle. If you're running it fullwidth using coils and radius arms it doesn't matter which you get. BUT if you're doing some custom setup you're better off starting with an earlier axle so you don't have to retube it.

cool.. I might pickup that 77 axle, I was reading that the cast part on the 78-79 makes it a little weaker.
