Gate King Tailgate Adjuster
Best for: Truck owners who want a clean OEM look
✅ Pros
- Uses existing factory tailgate
- Adjustable — multiple positions

Mount Type: Hitch vs. Tailgate-Integrated
Tailgate-integrated extenders mount to your tailgate hinges and provide the most stable, highest-capacity extension. Hitch-mounted extenders are easier to remove but use your receiver and have lower weight ratings.
Truck Compatibility
Tailgate-integrated extenders are vehicle-specific. Always verify your truck’s make, model, and year. Pair your extender with a quality truck toolbox to keep your hauling setup organized. Also see the best running boards for trucks to round out your setup.
FAQs
Are truck bed extenders legal?
Yes in most states. Loads extending beyond the bed must be flagged with a red or orange flag. Federal regulations allow cargo to extend 4 feet beyond the rear with proper flagging.
Can I use a bed extender with a tonneau cover?
The AMP Research BedXTender HD Max is specifically designed to work with most soft and hard tonneau covers — it mounts to tailgate hinges rather than over the bed rails.
Will a bed extender fit without drilling?
All options on this list install without drilling. The AMP Research lineup uses existing tailgate hinge bolts; the Yakima LongArm slides into the hitch receiver.
