Do XJ shackles work on Comanches?

[EnlistedManche]

I have way to much rake in the rear of my truck after going SOA. Looking to get lift shackles for a Cherokee that are .75 inch worth of lift. Which if I'm not mistaken is the original difference in XJ/MJ shackles. My real question is I've heard the leaf springs are slightly wider on the XJ. Curious if these will end up working for me. http://www.rustysoffroad.com/rustys-shackles-xj-75-extended-greasable-pair.html

XJ springs and MJ springs are both 2-1/2" wide.

mj factory shackles are 1" longer then a factory XJ.        aftermarkets are all XJ shackles, so just minus 1" from listed to get MJ length,

Ford F150 shackles. More info and PN around here somewhere

be careful about shorter shackles.  go too short and the leaf won't be able to flatten out and will bind.  

 

what about just throwing a couple bags of sand back there for a while?

I did a test with XJ shackles a while back. Picked up the back of the truck and then set it back down. The shackles inverted -> no bueno, so using xj shackles you'd have to run limiting straps.

 

Also, changing shackle length messes with your pinion angle which is not a good thing.

 

Better solution would be to bastard pack the springs, swapping out one or more MJ leafs with XJ ones, which have less arc to them.

Agreed.
