wrikenF-150, 4x4, 4.6
Last week I received the 2000 Rancho catalog and they listed Dual shocks for the newer F150's. Check their site and there you will be able to request one of those catalogs.
I know it's been some time since you started this tread, but just in case you still needed the information.
