Are you going to build the relocation boxes?

Here is another option:

I have a rough riding xj and I am probably going to go with a set of these, a longer shackle, and better shocks eventualy.

You are correct in using a smaller pack with a shackle will yeild a better ride and flex.

A shackle relocation box is a great idea if you can afford/have the knowledge to accomplish it. Another easy way to get a good shackle angle is to use a boomerang style shackle. Many manufactures offer these (JKS, RE, Rock Krawler, etc) and they help to improve the ride a lot.

If your wanting the 5-5.5" range I'd recomend going with a 3.5" leaf and a 1.5" shackle.

Also remember that springs (coil or leafs) are only a part of the equation to a good ride. Control arm angles, shackle, angles, and shocks are also a very key thing.

Let us know if we can be of any further help.

I am running 3.5 AAL with a 1.5 shackle.  And I beleive that I am right at the hieght that you are wanting.  Another option is you could relocate your shock mounts on something like this.  http://greatlakesxj.activeboard.com/index.spark?aBID=43793&p=3&topicID=19104604

I think that there are many things that you could do to help.  You are on the right track though.  The new leafs and shock will really help.  You could probably sell the Skyjacker leafs and put that money towards new ones.  They really aren't that expensive if you are buying just the leafs.  Make sure that you get full packs though.

i hadn't seen that before. looks like something to look into. BSfab did something along that line, just a bit more booty fab. still came out good though.

if i hadn't talked to you guys i would probably have had a new thread about shocks, lol.

i will address the leafs, and shocks when i do the 8.8, but is there any pros/cons to mounting the shocks on the same side?
