I recently purchased a 1986 4Runner that has a 4 inch lift an 33/10.5/15. I want to do a sas an ditch ifs. The tires I'm looking at are 37/12.5/16.5. I know I can buy a sas kit but am curious if there is anything else parts wise that I need to be looking for. I'm trying to find a donar truck on C list for the axle right now.
Thanks in advance for any input.

 

Basics...
SAS kit
Rear lift
Ifs steering mount kit
Big tars

How much lift will be needed to clear those tires I have no problem trimming fenders but would like a DD. it wont be so much for rock rock crawling as it will be more of a truck to get to places to hunt fish an trap out of. Just want a capable truck that can get me back in the moutains.

 

My truck has stock gearing and tires and getting up in the mountains can be a slow process. I can't imagine going to 37" without regearing.

 

I will be re gearing it along with header exaust aftermarket ignition air box plugs wires distributor. I'm just curious to find out if the axle will have to be moved forward an how much lift will be needed.

 

The axle will need to be move about 3-4 inches, with that comes moving the steering box.

Any of the sas kits should give you enough lift for 37s. The 3" spring are a 3" lift over stock solid axle springs, So then add the 4" of the axle itself, and a 3" Sas kit turns into about 6-7 inches of total lift.

Check out the SAS section, lots of good information in there.

 

Thanks for the info I am really hoping to keep this as low as possible so will try to stay away from going with 6+ inches of lift I was planning on running the 37/16.5/12.5 military tires that seemed to be in abundance but have not been finding very good reviews of the tires.

 

Search RUF.

Its rears spring up front. Its a way to try and get it a little lower than kit spring, but then you run into clearance issues.

 

Clearance issues I hope will be solved by cutting the body but in unsure if it will need to be tubed not looking for tons of flex as this will be my daily driver just want it to be a capable hunting truck to get me off the beaten path.

 

i have a buddy clearing 37's with no lift, IFS, 88 4runner, he just cut the hell out of the fenders. no rubbing though
