Heavy stuff like engines, transmissions, or anything else that can be strapped to a forklift pallet can be shipped from one Fastenal store location to another by Blue Lane Trucking. They're a totally owned subsidiary of Fastenal. Ive used them to transport engines and other big items, like a valve seat and guide machine that I bought on Ebay and shipped from somewhere in Wisconsin to middle Tennessee. Their rates are better than other LTL freight carriers.
