MJ leafs on an XJ???

[99ncxj]

any one know how much lift a set of 4wd mj springs will give to an xj? seems like since they are spring under and have more of an arch if you put them on a cherokee with spring over they would be good lift springs. Plus the mj shackles are longer too. anyone tried this?

XJ and MJ leafs are not interchangable as they are different lengths.

MJ springs are too long. But there is a better choice.

 

Use 1/2 ton Dodge B-van fullsize leaf springs and 1.5" lift boomerang shackles.

 

1/2 and 3/4 ton B-van springs have the same spring length from the front eye to the center pin. They are 3" longer from the center pin to the rear eye. The extra length will correct your shackle angle. The 1.5" lift boomerang shackle is needed because of the longer leaf so the shackle won't hit the shackle box.

 

The extra spring length and shackle will improve your ride and will increase your flex by allowing for more droop.

 

You can use your XJ bottom leaf to replace the overload leaf. If needed you can cut the eyes off of your XJ main leaf and use it as a full length add a leaf.

The main MJ leaf is too long, but if you retain your XJ main leaf and add in the MJ lower leafs you should get lift. Not sure now much though. From what I've noticed on forums, the S-10 leafs are way more common for use in a custom junkyard leaf pack. They give about 3" if I remember right.
