I still disgree.... Either Allpro has their facts wrong, or are marketing the springs wrong. The companies that manufacture the spring give the amount of lift from stock height, no lower. If they took into account the amount of sag they would have to market a spring for every degree of sag. Allpro say s that with a 2.5" spacer their 1.5" spring will be 4" to match 4" bracket lifts, so what you said contradicts that. If that was the case you would only get 2.5" lift, and have the same sag as you did before. When I had my coils custom wound by national spring they told me what I am telling you, the lift is from stock position. I had 3.25" coils wound, I sat about 1" lower than stock, and I did get an ass end 4" higher than it was. It leveled me out with the 3" rancho.

Something doesnt add up...ARB doesnt have an application guide to see how much lift those springs are. But if Allpro is marketing them as OME does, they are a 5.5" lift spring, from the stock height. If Allpro is assume EVERY 4runner sags 1.5" they are wrong, some sag more some sag less. With what they told you they dont even get a level stance with their 1.5" springs. You made it sound like they are marketing stock height springs as lift springs, I doubt that.

4runners never sat level, so you HAVE to lift it to get it level, about 1". Anytime your ride is higer than it was the day it came off the boat is lifting it.

Now when you say your runner sagged 2" low, do you mean 2" below stock, or level. If its 2" below level then yes its a 7.5" difference from where you were to where you are. If you sat 2" below level, you only sagged out 1", there for you got about 6.5" from the spring. By saying you got 7.5 or 6.5" that is from where you sat befoe you installed the spring, not from stock ride height, that is 5.5" of difference, what the spring is supposed to be.

And you said your six inches higher in the rear than the front, with the spacers and t-bar crankes. It sounds to me like you got more the 6" of lift...

OME does not ***usually*** make a coil for more than ~2.5" over stock. This is so you can still use stock stuff like driveshafts, brake lines, etc.

Lift height is usually counted as X over stock. Sag is not universal, so a 3" coil could give, say 10" of lift if you have sagged 7", for example. That is absurd and I would tell you so if you asked me about saying you had 10" of lift.

Let me go out on a limb and say you likely have an OME 860 or 862. Those are both really nice lift springs, FOR AN FZJ 80 Land Cruiser.

Get some stock rear 80 coils. They work great with what front lift you have.

If not, get a cheap bracket lift. They work great with the rear lift you have.

Thank you. My point was simply that he is sitting approx 7.5" over where you were before. Provided you were saying you sagged 2" from stock, not level.

There is a difference in receiving 7.5" of lift from a spring, and having a 7.5" lift.

As Flygtenstein said, you're using springs meant to lift FJ 80 2.1/2". What you get when you put them on 4runner depends on the weight you have in the back. If you don't want to spend more money to lift the front to march the back, then you should replace those springs with Stock FJ 80 springs or Downey springs.
Bsically, you've got the wrong springs to go with the front BJ spacers.
a simple search will reveals what others have put in the rear to match the BJ lift in the front.

Okay then, what is done is done, and the 4Runner is now sitting level and pretty due to some new (yet again, lol!) rear springs and a ProComp 4" front. Nice thing is, the Cruiser coils can fit in the box that the other new springs came in, making it easier for me to (hopefully) sell off.

I am writing this now because of my rear driveshaft: To get rid of the vibration, will the Taco front driveshaft (the back end of the front?) bolt right up to the transfer case, no problem? I would rather have an all-new driveshaft that will fit perfectly, instead of breaking out my drill and seeing what happens. If the Taco shaft won't work, who is a good shaft builder that sells at decent prices? I don't need a 1-ton drivetrain for a 3.0L engine, lol!

I do appreciate all of the feedback, and hopefully before long I can post pictures of the finished project for y'all. Thanks so much!

for my drive shaft I used the back half of the rear taco shaft. The nut on the xcase is bigger than the hole so I had it machined out a little...
