The CURT CrossWing is a lightweight fifth-wheel hitch designed for towing trailers with a gross trailer weight (GTW) of up to 20,000 lbs and a vertical load of 5,000 lbs. This hitch is engineered for ease of use, reduced installation complexity, and enhanced towing performance, incorporating features such as ShockDrop technology for smoother towing and a modular design that allows for one-person installation and removal. This guide provides a detailed overview of the installation process, safety considerations, and maintenance procedures for the CURT CrossWing, based exclusively on the information provided in the source materials.
Installation Overview
The installation process for the CURT CrossWing is described as moderately difficult and requires a set of specific tools. The installation involves securing the hitch base to the truck bed using a combination of bolts, nuts, and torque specifications designed to ensure the hitch remains stable and secure during towing. The following tools are required for installation:
- A ratchet
- A socket set
- A torque wrench
- A wrench set
It is essential to use the specified torque specifications for each bolt size to ensure the hitch is installed correctly and safely. The torque specifications are as follows:
- 1/2" bolt: 65 ft-lbs
- M14 bolt: 50 ft-lbs
- M20 bolt: 300 ft-lbs
- M20 carriage bolt: 100 ft-lbs
Prior to installation, the user is advised to read all instructions thoroughly and ensure that the tools are in good working condition. The installation process involves several key steps, including the removal of the hitch from the 20mm carriage bolt, the removal of lynch pins and clevis pins from the gooseneck ball coupler, and the reinstallation of the hitch in the reverse order it was removed.
One critical warning to note is that the upper M20 head pivot bolt should not be torqued. This bolt is designed to make contact but not apply clamping force. If this bolt is torqued, it could fail, leading to hitch separation during use and potentially causing severe injury or death. If the hitch head appears loose, the 20mm bolt should be removed and inspected for damage. If any cracks or damage are visible, the hitch should be immediately discontinued from use.
Safety and Precautions
Safety is a critical aspect of using the CURT CrossWing. The following precautions should be taken before and during the installation and operation of the hitch:
- Wheel Chocks: All trailer tires should be blocked with appropriate wheel chocks. It is important not to substitute objects such as stones or wood blocks, as these may not provide adequate stability.
- Lifting Jacks: The front trailer lifting jacks must support the trailer and rest on a firm and level surface.
- Vehicle Positioning: The towing vehicle must be stationary, with the automatic transmission in park (manual in neutral), the emergency brake applied, and the engine off.
In addition, users should be aware of potential interference with factory puck-mounted safety chain connections in the truck bed. If such connections are present, they will need to be unlatched and removed to accommodate the CrossWing base. The CURT chain connection can be placed under the gooseneck ball before installing the hitch to ensure that safety chains are properly engaged.
Connecting the Trailer
Connecting the trailer to the truck using the CURT CrossWing involves backing the vehicle up to the trailer. The V-shaped design of the receiver head allows the king pin-mounted upper connector to slide into place easily. If the vehicle needs to back in at an angle, the king pin-mounted upper coupler can be pivoted to the desired position. Once the connection is made, the connection should be secured with the slide-in pin located on the side of the hitch.
It is important to ensure that the connection is secure and that the hitch is functioning properly. The ShockDrop technology incorporated into the CrossWing helps to absorb shocks and jerks that may occur during towing, providing a smoother ride compared to traditional fifth-wheel hitches. This technology uses a rubber cushion in the center receiver section to soften the impact of any movement, reducing stress on both the trailer and the towing vehicle.
Maintenance and Longevity
To ensure the longevity and safe operation of the CURT CrossWing, a regular maintenance schedule should be followed. The manufacturer recommends the following maintenance tasks:
- Lube Plate Inspection: The lube plate should be inspected before each use and every 1,000 miles. If the lube plate is worn, it should be replaced with part number CURT# 16722.
- Head Pivot Point Lubrication: The head pivot point should be lubricated with a light dry film lubricant before each use.
- Torque 1/2" Bolts: The two 1/2" hex bolts should be torqued to 65 ft-lbs every 1,000 miles. After the initial 500 miles, these bolts should be re-torqued and then every 1,000 miles thereafter.
- Handle Pin Lubrication: The handle pin should be lubricated with a light dry film lubricant before each use.
- Torque Lower M20 Bolt: The lower M20 bolt should be torqued to 300 ft-lbs before each use and every 1,000 miles.
Following this maintenance schedule will help ensure that the hitch continues to function safely and efficiently over time. Users are also advised to inspect the hitch for any signs of wear or damage, such as cracks or deformation, and to replace any damaged components immediately.
Design and Features
The CURT CrossWing is designed to be significantly lighter than traditional fifth-wheel hitches, with a base that weighs only 60 pounds—65 percent lighter than conventional models. This lightweight design is achieved through a bridge-like truss construction that provides the necessary strength to support a 20,000-pound trailer while remaining easy to handle and install. The hitch can be installed and removed by a single person, making it a convenient option for users who need to frequently switch between towing and non-towing configurations.
The hitch also features grip handles on each side of the frame, which make it easier to lift and maneuver during installation and removal. Additionally, the center height-adjusting bolt can be removed to allow the hitch to be taken apart into two pieces, further simplifying the process of removing it from the truck bed.
For users concerned about potential rotation of the hitch during turns or when backing up, CURT has developed non-skid bed protectors (P/N: 16040). These protectors are placed under the CrossWing base and are held in place by the weight of the hitch. They do not require any drilling or welding and can be easily removed without leaving any evidence of installation.
Warranty and Support
CURT offers an industry-leading warranty for the CrossWing, which can be accessed by registering the product at warranty.curtgroup.com/surveys. This registration is recommended to ensure that users can take full advantage of the warranty coverage and any future support services. The warranty covers defects in materials and workmanship under normal use, but it does not cover damage caused by improper installation, misuse, or failure to follow maintenance instructions.
Users are encouraged to keep the original packaging and any accessories that were included with the hitch, as these may be required for warranty claims. If any issues arise with the hitch, users should contact CURT customer support for assistance, rather than attempting to modify or repair the hitch themselves.
Conclusion
The CURT CrossWing fifth-wheel hitch is a well-engineered solution for users who require a lightweight, easy-to-install, and durable hitch for towing trailers. Its ShockDrop technology, modular design, and comprehensive maintenance requirements make it a reliable option for both casual and frequent towing applications. By following the installation instructions, safety precautions, and maintenance schedule outlined in the manufacturer's documentation, users can ensure that the hitch continues to perform safely and efficiently over time.
