I installed Sumo Springs on my front suspension a few years ago and when I did there was about 2 inches of clearance between the leaf spring and the Sumo Spring and the ride was good.
Flash forward to today. The leaf spring and the Sumo Spring are in contact with each other and the ride is very bouncy.
Either the leaf spring has sagged and/or the Sumo Spring has extended in some fashion.
The ride height looks normal but I have no metric to measure against.
Any thoughts or experiences??

Have you added a lot of extras since you installed the Sumos? Did you by any chance weigh the vehicle by axle when you installed them? If you did have you weighed it now?
Leaf springs can loose their "arch" over time and extra loading, pot holes rough pavement contribute.
Have you checked to see if any of the leaves are cracked or missing?

I added Sumo several years ago. At the time I recall several inches with the front wheels hanging. Also recall them almost touching with wheels on the ground. I did not use the black spacers they provided.
Always felt my front was too low, but that seems to not have changed over the years.
