This is our final answer for our Cherokee leaf pack, which yields about 2 1/2 inches of lift. From top to bottom are: stock XJ main leaf, second leaf from MJ Metric Tonne, third leaf from MJ Metric Tonne, early '80s Toyota truck overload leaf, XJ fourth leaf. We basically mixed and matched until we had the ride we wanted. Make sure that no individual leaf is too much shorter than the next one in the pack, or it will be more likely to bend when wheeling. The Toyota leaf came in when we had to haul two axles and a transmission in this XJ. Because it is perfectly flat, there was minimal impact on unloaded ride and ride height. We did lose some flex (uptravel) off-road, but not enough to worry about.
