Early (1967-68) Camaro's, Firebird's, Chevy II's, (AKA Mono-leaf)
The best way to lift a Grand Cherokee is to install tighter leaf springs. The leaf springs can be changed in some vehicles to make them appear taller.
Coil springs. Leaf Springs. Torsion bars. If you just want ones made of metal.
Common types of springs include compression springs, extension springs, torsion springs, and leaf springs. Compression springs are used to absorb and store energy, while extension springs are designed to stretch and store energy. Torsion springs exert rotational force, and leaf springs are flat strips of metal used to support and dampen vibrations in vehicles.
I believe this is a trick question. I'm not familiar with a single model of Caravan, Town & Country, or Voyager that had leaf springs. They were all designed with coil spring and strut suspensions. If a Caravan had leaf springs it would be a bad idea to drive it with one broken, unless you want to scrape your undercarriage off on the road.

Leaf springs can be reset, or re arched. They will need to be taken off and taken to a specialty shop that has the machinery to reshape the springs properly.
Get new springs made.

Coil springs are spiral. Leaf springs are flat blades of steel stacked on top of each other. Air springs are bags of air. Leaf springs are cheaper and carry more weight (hence often rear springs are leaf). Coil springs are wound tighter at the bottom so that their spring constant is greater (this is to make a linear force after compensating for gravity).
Try Omix-Ada for replacement springs. HD Leaf Springs for my 1991 were spot on.
