Most trailer security products ask you to add a lock to your existing coupler. This one is different — the Hyper Hitches Coupler with Integrated Lock is the coupler. The locking mechanism is built into the body, which means your trailer cannot be hitched or towed without engaging the lock. No separate purchase, no forgotten step, no weak point from a bolt-on accessory.

Built from high-strength iron with stainless steel internal components and a durable powder coat finish, this coupler is rated for the heaviest towing loads in its class and built to hold up in outdoor conditions year-round.

• Rated for 21,000 lbs towing capacity
• Rated for 2,000 lbs maximum tongue load
• 2-5/16" ball
• Rekeyable lock core — change keys without replacing the coupler
• Upgradable lock core — move to a higher security tier at any time
• High-strength iron body with stainless steel internal components
• Durable powder coat finish
• Recommended for enclosed trailers, tilt-deck trailers, and flatbed trailers

Disclaimer: This product is specifically designed for use with enclosed trailers, tilt-deck trailers, and flatbed trailers. It is not designed or recommended for dump trailer applications.

Dump trailers can be susceptible to uneven load distribution and overloading, in most cases without the operator’s knowledge. These conditions can subject the coupler to significant upward forces for which this product was not designed, affecting its performance and suitability.

Although the product may physically be used with a dump trailer, doing so requires careful attention to the trailer’s weight capacity, load distribution, and the coupler’s rated capacities and limitations, particularly the upward forces placed on the coupler connection. Exceeding these limits may compromise the product’s performance and safe operation.

For these reasons, we do not recommend this product for dump trailer applications.

Inspecting the Hitch & Coupler

You must be absolutely certain your trailer will remain attached to your tow vehicle while moving, so keeping your hitch and coupler in good shape is key. Examine your entire hitching system carefully for any signs of rust, corrosion, cracks, or other damage. Test the coupler's latching mechanism to ensure it is neither too easy nor too difficult to operate. Ensure the coupler is not loose-fitting, as a loose coupler means a loose connection between the trailer and the tow vehicle.

Remember, the coupler is not rated for significant upward force. Loads positioned behind the axles can create upward pressure on the coupler, potentially causing damage or failure — proper load placement is essential. Don't forget the safety chains. In an emergency, they can be the one thing keeping your trailer attached to you. Inspect the links carefully for wear or rust.

• Inspect the coupler and hitch components for signs of wear, damage, or corrosion before each tow
• While towing, inspect your coupler and hitch components every 100 miles
• Verify you are using the correct size hitch ball and that all components meet the required weight ratings
• Ensure the coupler fully engages and securely latches onto the ball — always visually confirm it is properly locked
• Keep the coupler clean and free of dirt or debris that could interfere with proper operation
• Follow regular maintenance practices to keep moving parts functioning correctly
• Do not tow if the coupler is damaged or does not latch properly — repair or replace it first

The lock core is rekeyable and upgradable — you can increase your security level at any time without replacing the coupler.
