Ok I will put a nail in this thread right now lol it is possible.:shitstormretarded
If we take the whole leaf spring and flip it over, it will be a stiff ride but it IS possible to do and will lower the truck the least an inch and a half.
It is NOT possible. Yes in theory you could fip them around, but it flat out will not work on our trucks. You need to take into account the full suspension geometry, not just some 1950's ratrod forum where somebody made it work on their rat rod 39 coupe and assume it'll automatically work on our trucks.
First off, an inch and a half drop? You're dreaming. It would probably be a full foot drop, if not more. It would almost put the axle ABOVE the frame rail. Our leafs have a significant arch to them stock. WHen you put weight on that arch, it flattens the leaf out closer to flat (just slightly arched). When you FLIP the leaf upside down, that arch is now going up, not down. And when you put weight on that flipped leaf, you're no longer trying to squish that arch flat when you put weight on it, you're trying to arch it even MORE.
See the attached pic to explain. I found a pic with a stock leaf and a drop leaf, but it's a good comparison for what it would look like compressed and uncompressed with the trucks weight on it.
The left pic would be stock setup. The lower leaf with the big arch would be uncompressed, truck in the air, rear dangling free. The upper leaf with the small arch, would be the compressed, the truck on the ground, weight on the rear.
The right pic would be the flipped setup. The upper leaf with the big arch would be the truck on the ground, weight on the rear, the spring trying to arch more under the weight of the truck. The lower leaf with the small arch would be uncompressed, truck in the air, rear dangling free.
So you can see you're not only gaining the difference in uncompressed heights on a drop (probably a foot+), you're also gaining the delta of height in compressed one direction vs. bowed in the other direction on the drop (probably another 6"+).
