New Dimensions Tower is not OEM. The owner of New Dimensions used to be a part owner of Xtreme Marine which has been renamed Xtreme Tower Products.
XTP is the world's largest tower manufacturer and has made more than 45,000 towers.
XTP is currently OEM on Mastercraft, Supra, Moomba, Tige, Malibu (select models), plus about 20 makes of run-about boats. New Dimensions is not OEM for any make of boat. They have basically copied the older XTP OEM designs.
XTP has now made the actual Mastercraft Zero Flex OEM tower available to the aftermarket. Wakeside.com discontinued New Dimension Towers and now offers XTP OEM towers in its place.
Below is a link to the Mastercraft OEM tower.
