Conner's answer was just what I needed. I'm having a problem with the leaf spring suspension on a tandem goose neck trailer. It has 8K Dexter axles. Breaking springs, damage to the spring hangers and bad tire wear. We load a Bobcat track loader and drilling supplies. Not over loaded.
I'm thinking about trying the Sumo Helper springs or a shock absorber system. I like the Etrailer.com site.
Have ordered trailer parts from the site before. Thanks!
