You can add a 1" spacer to the front springs and get 2.5-3 inches of lift. I also here the ESPO springs...which are really for a javelin gives a bit of a lift...so you could do some new javelin springs and like .5 or .75 inch spacer on the spring.
Springs -
http://www.springsnthings.com/AMC-suspension-parts You'll have to call in to make an order.
Spacers - uhg I can never find the site where I've found the cheap spacers for the coils, but there is usually a couple on the bay.
The backs you can get an add-a-leaf or get an extra leaf from a couple different vehicles. I think the S-10s fit and the Cherokees.
You can buy some Air Shocks for the rear too and that might lift it up a bit. There is also usually a set or two of some rear shackles that I know a couple members have used on their Eagles. Those can be used for like a 1"-4" lift, depending on which hole you use.
