This ball was designed specifically for our True Tow Weight Distribution Hitch as it offers higher clearance for a better turning radius. This single tow ball is NOT compatible with the 180 Hitch.
Stainless steel tow balls can still show surface rust, particularly after use in a coupler and exposure to water/salt. This rust will not spread past the surface of the towball and it will not affect the performance of the towball. The rust can be cleaned up and removed with a scotch brite/brillo pad.
