So some wisdom for those who are looking at doing this and some things I have learned with the Yota pickup crawler which is SAS'd
-This is not a plug and play kit no matter how much they say otherwise. You will have to do lots of fab work to get it to work right and even then you will have to tweak and tune and dial it all in. I am having to do this with a leaf sprung SAS.
things to consider:
:you will have to design and adapt steering.
:mess with the ABS
:breaks will need to be adapted and modified to run the bigger ford calipers
:you will have less ground clearance with a D60 w/ 37s than with a D44 w/ 33s
:you'll have to re-gear the axles
:lockers are not cheep
:coil-overs are not cheep
:custom drive shaft again not cheep
:you are going to get really really tall ie: higher center of gravity
Cost break down of major components:
4500-kit
2000-axles -found on FB MP
300-D60 gears
300-S10.5 gears
2000- 2x ARBs
1000- coil overs
-10K+ easy thats not including tires
-Our ABS dose not play nice with anything even its own system. Many of you who live out east and go in water frequently know what I'm talking about. The ABS system really limits on what you can do with the drive line on the truck and make the overall computer happy. Even if the dana60 speed sensors are "compatible" its still not going to be 100% and which then screws with other stuff.
-Gears get over rocks and we have one option for T case gears: an Atlas which in reality because of the cost and the computer/ABS problem the Atlas is really not an option. O and you'll have to get an adaptor for it
There is a reason why that 1980s shiat box Yota thats like 3 grand and has a 90HP 22re keeps up with the LS swapped JKU on 40s: a 217:1 crawl ratio.
-if you want to go over 35s or seriously wheel with 35s you are probably going to want to get a sterling 10.5 for the rear. Dana 44s are more than strong enough for 35/37s but we don't have the option of chromoly axle shafts which a stock S10.5 axle shaft is more than enough for 37s.
-Bead locks are amazing on the trail but they are costly for aluminum and supper heavy for steal weld on ones and you pretty much are forced to upgrade axle shafts due to the added traction and even then its not a promise you won't break or you'll move the breakpoint to another spot.
The second gen Nissan community is really spoiled. Bang for its buck a Titan swap is just amazing its
all bolt in and used just about all factory parts. ~10" of travel on factory geometry is just insane for an IFS, there is a reason why TC doesn't make a long arm kit for a titan/X/Frontier, there is no reason. There is no reason for custom fab or anything like the Yota guys or other brands do. Lots of us have no experience or concept to what goes into a solid axle swap, I know I didn't when I got the pickup and I'm just trying to convey the scope of what is involved.
I would absolutely love to SAS my or Mrs. Unseen's X but the cost/benefit is just not there for me in my mind, Ive gone around for hours with Bill, Greg and other people about this and I personally just can't see it.
but someone do it so I can live vicariously though you haha!
