Leaf spring ?

I have a 99 xj with a RC 3inch lift..

How could i go about getting 1/2 inch more lift in the back?..
I have add a leafs now on factory springs ( Been that way for 1 1/2 yrs )
There not sagging, just want a little more in back.

could i just add another leaf to the rear?. ( second leaf from a factory pack?. )

Do they make a shackle thats 1/2 inch longer?

Thanks
Jonathan

MJ shackles? 1/2" blocks? Zero-rate AAL? UBE?

Just add another bottom short leaf.

Comanche shackles will give you about 1/2" to 3/4" of lift. easily found in a Pick-a-part Junkyard, for probably about $10-$20

I went to the J-yard today and picked up some MJ shackles (20 bucks). messured a inch longer. and ride height in the rear went up one inch also.

thanks guys
