No, on doubling the shocks or other hardware.
I am in the process of adding Sumo Springs to try to mitigate the curb roll, and sway from driveways and 18 wheeler bow wash. If the handling improves, that would be a bonus, but I'm only after a low speed rock and roll improvement. These things have very mushy suspension, and the gap beteeen the frame and suspension bump stops is pretty wide, probably to soften the ride, but the trade off is serious wobble entering/exiting even slightly angled grades and driveways. If it works, great. If not, no harm done.
