SHIPPING: All our products are offered as "will call" FOB Portland, OR. -but we can help you find a shipper that can give you quotes.
"Will-Call" means the products are intended to be picked up at our location and may not be packaged completely that will avoid damage by rough handling during shipment. This is why we strongly recommend that if you are having the products shipped, that you request a dedicated shipping service, on a deck-over or flatbed trailer, and that the load will be tarped. A "dedicated shipping service" means the truck picks up at our location, and drops off at your location. Do not accept a local pick up to a distribution center for transport. If only ordering subframe pivots, those will be shipped after being wrapped and normally have not problems in transits.
