Do you have lifted truck or big cab & chassis with a tall bed height? If so, you might want to consider ordering your gooseneck with a 6″ taller riser. Our 6″ taller riser will keep your gooseneck trailer riding level. If you aren’t sure about this option we recommend taking your truck to your local PJ Trailers Dealer and hooking up to a standard gooseneck to see if the taller risers are needed.
