Ok i'm a little confused and hopefully someone can clear it up for me. I have an 87 4runner that I would eventually like to do a SAS on....now if you buy a kit they give the option of 3" springs which state that it'll give you 4" of lift. I'd like to do the SAS and have it stock height or close to it. So when I find the donor 85 or older toyota to rob the front axle, can't I take the springs and hangars from it and achieve the swap with little to no lift???

 

Sure you can.

If needed you can even source new stock springs for the donor you end up with.

The kits with the added lift are just a marketing ploy wow I can buy something to do a lift and SAS at the same time.

Then you also need to lift the rear as well

awesome info guys! I sure appreciate it. I'd like to do the swap and if it ends up being 2-3" higher thats fine too...I just didn't want a 4" lift from doing a SAS...hope that makes since

 

those 3 inch springs with a hanger kit give you like 6 inches of overall lift. you will not have room for high steer without lift on an ifs frame

 

^ This. My sas using ruf springs gave me 3" of total lift using skys parts, and the springs are pretty much flat. Getting an IFS truck to sit that low with a solid axle requires some work. You need some space for the steering / up travel. In order for it to sit as low as you want it, youll have to do some frame notching/bracing. Other options are making your own "low steer" or swapping in a push/pull box that came with the solid axles, but thats a lot of work for a sub par system. Solid axle frames have a higher arch in the front, that why its easier to make them sit lower.

 

Yeah things to account for when buying a kit is the hanger already adds about an inch or two just from welding under front, plus a 3" spring, and if you get a longer shackle as well.. This easily can add up to 6-7"+.. Keeping it low makes it real difficult to set up your steering like rattle said, it's better to start with a 2wd truck since the frame has more arc to it like the earlier solid axle trucks. Using RUF and a small shackle will keep it lower but still not "stock" unless you want to hack your frame.

 

hmmm alright I see...man this is a lot to think about and figure out. So looks like lowest I can be without all the major modifications to the frame would be about 4" after the SAS.

 

another question i'd like to ask...i'm soon gonna be installing a 10-12 cognito lift on my duramax and it comes with 8" deaver leaf springs....so can I use my stock rear springs from the duramax on the front or rear of the 4runner???

 

Probably, youll have to make new mounts, and will probably want to take a leaf or two out depending on how thick the pack is. Chevy springs are a common swap for the rear and will lift if about 3-4"
