We have tried to include pricing on the most common fork sizes. We don't generally charge differently for various fork thicknesses but do produce Fork Sox to fit snuggly. Please let us know if your fork's thickness is different than the standard listing. For lengths other than listed also specify your fork's length. Pricing will be to the next longer size (46" will be the same as 48"). If you prefer, don't hesitate to email or call and we will quote you the size you need.
