I just had new springs put in the back of my Crestline Ambulance (E350 Ford). The 10 pack leaves are rated the same as the 9 leaf packs. There's little arch. So the truck sits level, the spring shop added a 1" steel block on the drivers side (it's about 650 lbs heavier).
At the rear wheels it currently sits 2" higher. This means the tail is 3-4" higher. The plus side is the bumper won't drag on the ground as much...
How much will the rear springs settle? I know there is a wealth of knowledge here. For more info, the springs are rated at 8000 lbs (4000/side). Empty there's about 5800 lbs on the rear axle - Dana 70 dually axle... I'd guess about 4800 lbs on the springs. I'm thinking about 1" over the next 6 months (perhaps less).
