For Mopar specific stuff, Performance Mopar Handling by Mark Martin. I think it has gone by differing names over the years.

For overall suspension info and analysis way beyond anything I've ever found for mopars, Building the Pro Stock/Late Modle Sportsman by Steve Smith. While almost all GM specific, it give great info about geometry, impact of changes, inter-relationshipa of everything and optimization of stock style and fabricated chassis.
