The topic of SAS ( Solid Axel Swap ) gets kick around a good bit now. People want more articulation from there suspension. The independent suspension is proned to limited articulation and to breakage due to large tire size . Not that a solid fort axle will not break under the strain of lager tires either. The solid front axles just have few joints to fail.
I have seen several solid axles done with all kids of axles. I seen D30 form TJ swapped in with custom lower control arm and coil springs. I have seen D44 from 73 – 79 F100 and F150, 66 – 77 Bronco, and 78-79 Broncos, these suspension used a Coil sprung C bushing radius arm combination. The following two picks are form the early Bronco form 66-77 and the 73-79 F 100/ F150/78 -79 FS Bronco.
73-79 F Series /78-79 Bronco
To rap up coil spring. I have also seen the D44 form 94 Ram 1500 and its front coils spring and contol arms used.
The most common axel swap I have seen is the old reliable leaf spring. F250 and F350 have had D44 or D60 front leaf sprung suspensions form 73- 96. I am not sure about other dates.
While a solid axel swap is time consuming requires lots fabrication, the end result is always impressive if the swap is done correctly.
There are few to no completely bolt on SAS kits but is you drive a Ranger, B2 Bronco or Explore with the D35 TTB front suspension. I belive the range is 84 – 97 you in luck this is a total bolt on kit that is $1799 plus the cost of the Axel. http://broncograveyard.com/bronco/i-...conversion.htm
If you drive some thing a little newer good luck. Just kidding. James Duff makes a sent of Radius style arms that I have seen used very successfully.
These arms are about $699.
Cage Offroad Products also makes a set of radius that I have seen used. These arm are a good product. But you may have to morage you house @ $725 for the set.
So if you like this coil sprung radius arms style suspension you can puchase the C bushing brackets and weld then to any axle that will fit you application. For around $89.
The ones pictured are from here.
By no mean am I the king of SAS but I though this would be a great starting point. For those who want to tackle this project. If any correction needs to be made or you would like to add info post up!!!
Happy SASing !!!!!!!!!!!!
