ok, ive been looking in to a SAS for a while now, and ive thought of buying a kit for leafs, or custom making one.

Now im thinking it would be pretty cool to do an SAS with an FJ80 axle, so i get the great flex of coils. This way after i do the swap i would just buy a land cruiser lift for the front end and buy the appropriate size springs for lift on my stock 4runner axle in the rear.

has anyone seen a buildup like this, or have any thoughts or tips about the idea?

 

It is a bit more complicated than buying a Landcruiser lift. It has been done, there are threads on ttora.com and Here: http://pirate4x4.com/forum/forumdisplay.php?f=12
What are you going to do to match the rear axle? Spacers would probably work...

Stock Toyota front axle measurements for comparison:
55.5" wide, 29" spring perch centers, '79-85 Toyota trucks and 4runners, SA Hubs
58.25" wide, 29" spring perch centers, '79-85 Toyota trucks and 4runners, IFS Hubs
63.5" wide, (set up for coil springs) 90-97 FJ80 and FZJ80 Landcruisers
'86-95 IFS front end is about 58.5" wide
'93-98 T100 IFS front end is about 65" wide

Toyota Rear Axle Widths:
55" wide, '79-85 4wd trucks/4runners - 6 Lug
58" wide, '86-95 4wd trucks/4runners - 6 Lug
56" wide, '79-95 2wd Trucks - 5 Lug
60.75" wide, '95.5-up Tacomas/4runners

 

snag a rear axle too???

 

yeah, i was thinking spacers

im runnung a 91 4runner, and i plan to do a sas for my senior project.
my friend wheels a XJ with a 8 1/2 long arm lift and its coil sprng up front, so would a toyota be the same concept? like extending the control arms and making different mounts and such, or is it a differnt set up?

 

the junk yard i plan to get my stuff from is pretty expensive, but they have bot axles so i could grab both, just cost good bit more

 

you cant use the rear if you like your gas tank where it is. The rear diff is offset to the passenger side.

 

i know there is someone on ttora who did this on a taco

 

I am currently doing a 2wd to 4wd/sas on a 99 3.4 auto 4runner using a 95 LC axle with leafs. Leafs were the wrong way to go, it will have a 3link in the future. I am also using the front coils off the front of a 91 or 92 LC on the rear to get about 4" of lift.
