Make Roof-Top Kayak Loading Easier on Taller Vehicles

Getting a long kayak onto the roof of an SUV, truck, or van can make loading and support more difficult than it needs to be. The Boonedox Tailbone mounts in a standard 2-inch receiver hitch to extend the vehicle's roofline with an adjustable-height crossbar, giving kayaks, canoes, and other long cargo an additional support point for loading and transport.

Built Around Easier Kayak Loading and Roof-Top Transport

• ✅ Hitch-mounted design fits a standard 2-inch receiver, adding rear support without requiring a permanent roof-mounted extension
• ✅ 50-inch fixed crossbar creates a wide support point for kayaks, canoes, and other long cargo
• ✅ Up to 12 inches of height adjustment helps position the crossbar for taller SUVs, trucks, vans, and different roof heights
• ✅ Removable guideposts help align the kayak and keep the loading path easier to manage as the boat moves into position
• ✅ Particularly useful for side-loading, giving paddlers another way to move a kayak into roof-top position while reducing the need to place it directly onto the vehicle
• ✅ Aluminum construction keeps the Tailbone practical to handle while providing a dedicated structure for repeated transport use
• ✅ Integrated gear grooves provide attachment points for additional compatible accessories

Real-World Performance

The Tailbone is especially useful when roof height makes it awkward to move a fishing kayak directly onto a vehicle rack. Set the crossbar height for the vehicle, use the rear support point and removable guideposts to help position the boat, and work the kayak into its roof-top transport position. The design also supports side-loading when that approach better suits the vehicle or loading area.

Add a Better Loading Point Behind Your Vehicle

Use the Tailbone to turn a 2-inch receiver hitch into a practical rear support point for loading and carrying long watercraft at roofline height.
