Got a 74 or 75 SJ that you would like to lift...that 4 spring kit sound good...well before you even pick up the phone to call and order be 100% sure that you do not have post mount rear springs.

After this past weekend that I went through...I most deffinately would not want anybody to go through what I just did.

Here is my long story made short...

I went and bought a Rusty's 4 spring 4" lift kit for my 75 cherokee NT. After getting I started early saturday morning to put it on. Front springs went on just dandy, had one stuck bolt, but I just hot wrenched it off...no biggy. Then I get home saturday night and get on the FSJ chat on IRC...start talking to RVRBEAST, when after describing what I had done and will have to do he mentioned that it sounds like I have post mount rear springs. This is a very bad thing as the legth of the springs and diameter of the bushings is much different. So he talks me through how to do a shackle flip (thanks again Todd). Which in the end worked out ok...but I dont have new rear springs...they are sitting in the back of my truck.

All in all it worked out ok in the end...I have about 4.5" lift up front, and 5.5" in the back. (pictures will be posted later)

But for anybody who may want a 4 springs kit..be sure to check for this...as it is not fun to not be able to use what you dished out alot fo money for.

I'm glad he got to you before you were knee deep in it. That would have been much worse.

I replied to your post in the classifieds.

What are "post mount rear springs"?

There is post mount and box mount. Post mount was the stanard style from 62-73. It seams AMC used up extra parts until they ran out of them. My truck was made in July of 75...which is why it was surprising to findout about post mounts.

Looking at your rear springs, post mount is there front eye of the spring boltsto a big stud which is connected to the frame, and the bottom part of the rear shackle is connected to a similar stud. If you remove 2 nuts, the whole spring will slide off sideways.

With a box mount, the front eye of the rear spring bolts into a braket, with a single bolt going through, the rear is also bolted into a braket. You cannot just slide the spring off liek you can with a post mount, you have to remove the bolt, then lift the spring out of the braket.

Hope that helps a Bit, River Beast has pictures he can possible post them here later.
