Sumosprings

[whirnot]

After putting new springs on the front of my 51 F1 it seems pretty choppy even though the shocks seem to have good action to them, (removed and cycled). I am considering putting Sumosprings in. They look to be a perfect fit, and with their variable compression I think it might help. But I thought I would ask if any of you guys have tried them. I have them on my motorhome to reduce sway and they give a nice ride there.

The problem with leafsprings is you have to get over the friction between the leafs before they start working...so if not well lubed they get bumpy unloaded.
Parabolic leafsprings is a solution to the issue reducing the contact area between the leafs giving you a smoother ride.
