The Curt CrossWing 5th Wheel Hitch is designed with a unique 4-way pivot system that allows for maximum movement and flexibility. It is built to reduce stress on the trailer and truck by absorbing shock and preventing jerking and jarring. The CrossWing is also easy to install and remove thanks to its 3-piece design.

The CrossWing is designed to raise the bar on towing. It is engineered to be solid yet easy to handle by combining robust strength with state-of-the-art technology, all while remaining lightweight. Compared to traditional 5th wheel hitches, the CrossWing is 65% lighter with a main body weight of only 60 lbs. With its lightweight design, assembly and installation are a breeze and can be done by one person with no extra hassle.

Although it’s light in weight, the CrossWing’s strength and toughness are not jeopardized. It is constructed with tough, premium steel and has a reinforced head connection point that provides exceptional strength. Its unique coupling system eliminates guesswork by offering a visible contact surface, and its head channel guides the kingpin into place for easier hookup, saving you time that you can spend on the road instead.

In addition to its strength, the CrossWing is packed with cutting-edge technology that is a step above the rest. It allows fore, aft, and lateral head articulation when connecting on uneven terrain and features ShockDrop technology that reduces jerking and jarring for an overall smoother tow. Finally, the CrossWing is finished with a premium, carbide textured black powder coating that protects against rust, ensuring this 5th wheel hitch will provide comfortable, superior rides through many miles to come.

(5th Wheel Hitch Buying Guide)

Need help selecting the correct hitch for your truck? No problem! Follow along below as we show you exactly how to make the correct choice for your next adventure.

How to Choose the Correct Weight Capacity

Before selecting a 5th wheel hitch for your truck, it is important to know your towing capacity and gross trailer weight. Towing capacity is the maximum weight your truck is rated to tow. Gross trailer weight is the total weight of your trailer when it is loaded and ready to be towed. Towing capacity is always limited by the lowest-rated towing component. For this reason, we recommend purchasing a 5th wheel hitch that meets or exceeds your truck’s towing capacity.

How to Choose the Correct Mount Type: ISR or OEM Puck

ISR which stands for “Industry Standard Rails” are above-bed rails used to mount a 5th wheel hitch. They are built with industry-standard mounting points, accepting a broad range of 5th wheel hitches from various manufacturers as long as they conform to the ISR pattern. The rails are secured directly to the bed and frame with vehicle-specific brackets.

OEM Pucks come straight from the vehicle manufacturer. These pucks consist of a series of holes in the bed, making for easy, drill-free installation of a 5th wheel hitch. The puck systems are specific to the vehicle manufacturer. For example, Ford, GM, Ram, and Nissan each offer their own OEM puck system, which differ in size and spacing. Therefore, you’ll need to ensure the 5th wheel hitch you choose is designed for your specific year, make, and model.

How to Choose the Right Base: Fixed vs. Slider

Choosing the correct base for your truck is important; a fixed base positions the hitch directly above the rear axle. A slider base allows for the hitch to slide back when making tight maneuvers for additional turning clearance, so contact between the truck and trailer does not occur. The correct base choice takes into consideration both the truck and trailer, particularly the bed length.

As a general rule, trucks with a bed shorter than 8′ should use a slider base to ensure adequate turning clearance between the truck and trailer when making tight maneuvers. A fixed base should be reserved for trucks with an 8′ bed. Please note that there are exceptions to the rule, such as trailers with a rotating pin box or tapered nose. When in doubt, measuring is always the best way to determine the correct choice.
