NICE PICS!

Okay, the standard Wag, Cherk J10 shackles look exactly like those, so I'm gonna say, they are probably stock.

The long, thicker (non-tapered?) second leaf is way long for that shackle box.

All the leaf-springs I have seen in 1979 and newer FSJs are not that thicjk and are tapered, thinner on the ends, thicker in the middle.

I think the way you have the shackles now is the only way they will work with a second leaf that thick at the end. They ride the opposite direction in the front, open side of the shackle faces the axle.

However, I still believe (could be wrong) that you got a J20 or long WB J10 lift kit there.

Even if you put 1000 pounds of weight in the back of that rig...I doubt the rear axle would relocate to the centered position, like it should be when the suspension is unloaded.

Technically, the rear axle tends to ride a bit forward when the suspension is unloaded, centered when lightly loaded, and a bit rearward when heavily loaded.

The front suspension functions/flexes/moves the same way, but opposite directions. Most of your spring flex should happen at the rear of the rear springs and front of the front springs...that's why the shackles are located in their relative positions.

Well BJ's and Alcan agree that the springs are wrong. They sent me a return authorization so send them back to Alcan so new ones can be built. While the springs are off I installed a pair of banger sliders from BJ's.

Sounds like they are doing the right thing.

BTW -did you ever notice if the slip-joint on your rear Drive Shaft was compressed or not? Just curious.

I am supposed to get the new springs Thursday. I will post pics once I have them installed.

Alcan sent the new rear springs and they are installed. The spring no longer rests on the hanger box. The front and rear are now a lot more even and the rear wheel is centered in the wheel well. The ride is also a lot better with the spring able to travel since it isn't resting on the hanger box. Of course in typical Jeep fashion, on the maiden voyage it stranded me on the side of the road. The old Presolite distributor stopped working correctly. I have now installed an HEI distributor and new wires. She is running better than ever....for now

That rear wheel still doesn't look centered!

Maybe because of the angle the pic is taken from? The other side looks way better.

I measured and it sits about 2 inches forward of center in the wheel well.

With a longer spring you SHOULD use a longer shackle so when the spring flattens out it has someplace to go and not bind.. It should look something like this. Also Your spring loop in the rear should wrap DOWN not up as your pic showed! Maybe you installed them backwards, ie. front to rear. That would explain the center pin location being off! Both ends of the springs you have may wrap the same way but the shackle is definitely in backwards according to your picture.

Yes, the shackle is mounted backwards in the pic. That was the only way they would mount wirg the incorrect springs I got initially. They are in correctly now with the replacement rear springs. The spring is definitely mounted correctly. The spring eyes are different sizes and can only be mounted one way.

I believe I asked this before: What is the measurement from the front Spring-Eye center to the centerpin? What is the measurement from the rear Spring-Eye to the centerpin?

It looks like your drive shaft is too short for that much lift.
