Parabolic Springs
Using automotive design technology, the parabolic spring is a slipper type which has only one leaf.
This single leaf tapers at the ends and is thicker in the middle of the spring. The performance of these springs is similar to that of multi leaf slipper springs, but without multiple leaves lends itself to hot dip galvanising for the marine trailer industry due to it’s ability to reduce the rusting that naturally occurs in a salt water environment.
