I think it will work. The stableload kit comes with 3 wedges for each end of both rear springs. On my Ford, I did not have space for all 3 wedges, in fact, I had to lift the tail end to fit in 2 wedges. I only need 2 wedges, and have to take a little weight off to engage them.
Handling of my rig is much improved with the stableloads. So much that I am planning to add the uppers. YMMV
