Mj Rear Spring Shacke Question


Recommended Posts

I was looking at an adjustable rear leaf shackle to get about an inch of fine tuning for a 3" rear leaf spring lift and a 4.5" front lift.

 

They are available but the supplier did not know if the XJ application fits the MJ? I think the width may be different. Does anyone know if they interchange?

Warrior Products makes a 2" XJ lift shackle that will give you about 1" lift on an MJ. They're not adjustable (no multiple holes) unfortunately. That's what I installed on the back of my rig, 5.5" RE coils with an extra coil isolator, and stock 2wd rear springs in spring over. It levelled the truck out perfectly.

Just an update - went with General Springs (3/2) Metric ton / Military wraps from another thread on here and Chevy Drop shackles. The ones I bought from AutoZone were around $40, and once flipped gave almost  3" of lift, in addition to the 2-3" from the new leaf's. If I modify the shackle, could bring it down about 1 1/2" but for now I'm leaving it at 3".

 

Had to grind a 1/16" off the poly bushing end, the heavy steel insert would have pushed the shakle perches open. That and shimmed the other end where it attached to the leaf spring, was about 1/8" too wide.

 

Now the truck is sitting with about a 2" rake!

 

Not sure how adding length to the shackle will produce good flex, but we'll see...
