Fifth Wheel to Gooseneck Adapter, Adjustable Height 13''-18'', Bolt-On to Standard Kingpin Box, 20000 lbs GTW 4000 lbs VTW, Fits Standard 5th Wheel Camper, Includes Safety Chain

• Converts your standard 5th wheel kingpin box to gooseneck hookup, no need for a large 5th wheel hitch, saving truck bed space and simplifying towing. Important Installation Warning：This bolt-on fifth wheel to gooseneck adapter REQUIRES drilling 4 holes into your camper’s kingpin box for bolt & nut mounting. Drilling modification on your camper is mandatory. Confirm you accept drilling before Purchase
• Bolt-On Design, Stronger Than Clamp-On Adapters: Bolts securely to the kingpin box for a rigid, rattle-free connection—no wobble, looseness or shifting like clamp-style models
• Adjustable Height 13"-18": This adapter uses a hole-free inner tube locked by two large clamping bolts. Friction between inner tube and outer sleeve holds weight, enabling stepless height adjustment without fixed gear positions
• Note About Height: Torque the two side clamping bolts alternately to 100–110 ft-lbs, Adjust height only when the camper is disconnected from the truck. Retorque bolts before long-distance towing
• Heavy-Duty 20000 lbs GTW & 4000 lbs VTW: Built for heavy-duty use with full-size 5th wheel RV trailers, safe for highway and long-distance travel
• Includes Safety Chain & Mounting Hardware: Comes complete with safety chain and all necessary hardware for easy installation
