Going SOA, what springs will I need

We have NO MJ stuff in the UK, so its XJ or ZJ/WJ only stuff available for me. I am fitting a set of WJ diesel axles under my MJ (because I have a set & they are 3.91 diffs & variloks).

So if I will be going SOA & using an XJ rear spring what amount of lift spring will give me a 4" lift in the back with my setup? (a D44 has a 2-5/8"OD tube)

thanks

The XJ leaf springs won't work, you're pretty much stuck with the MJ springs and you can either run them straight stock or make a bastard pack out of them. When I did my SOA, I just use my stock springs. Mine were sagging a little so when I swapped the 8.25 and doing a SOA only netted me 4.5" over stock. A brand new spring will net about 5.5" going SOA. Since you're swapping axles...old axle centerline to bottom of leaf perch + new axle centerline to top of leaf perch will be your lift.

Will an XJ add a leaf fit in an MJ spring pack? I think I will be making a leaf pack up.

An AAL from an XJ will net you no lift.
