Found a set of axles a 8.8 with 4.10s and. Dana 30 with 4.10's the 8.8 is already converted for a Cherokee. Now will I need a different proportion valve? And it will b a 4.5 lift will I need axle shims for pinion angle? The front lift is already on the axle but sounds like I will have to fab the rear lift. All the shocks are there as well. I currently have 3" rc lift on my 2000 xj. Thoughts or ideas welcome

 

no valve and yes for the shims unless you have a sye

 

Proportioning valve:

I assume the axle has disc brakes? If it has disk brakes then you can use a WJ prop valve. I kept the stock Xj valve and haven't had issues.

8.8 pinion angle:

That's all going to depend on where the PO installed the new spring perches. You're going to have to measure after you get it installed. Maybe, maybe not.

Front lift installed on the axle? What's that mean? Fab the rear lift? I don't get it.

 

C'mon man. Dude posted about the most vague question he could have and you post up with certain answers.

What degree will his 8.8 be mounted at when he installs it?

Btw, your shift key seems to be broken.

 

The front lift is complete. Its all there I don't have to do anything but bolt it up.

I have no idea how he had the perches welded

The rear lift he does not have the shackles and he was using blocks which I won't use.

So I have to Fab up the rear lift myself I think I can use my 3" lift leaf springs I have plus a shackle seem sufficient?

Anything else anyone doesn't understand.

 

Edit

 

Sounds good, may we have a photo of the 8.8 and also please measure center to center of the brackets on the 8.8 just to dubble check his stuff,

Okay I just thought of one! Um do you have a sye? If not then you won't need Shims if you do you will half to mount your 8.8 (with weight of the jeep) and measure to see if you need shims

 

Again, you have no idea where he put the perches.

He could have put the perches at 10* above the t-case.

It wouldn't matter if he had an SYE or not. Especially since he was running blocks.

OP, you thru me off with having to "fab" the rear suspension.

The rest of the plan sounds good.
