The CURT adjustable trailer hitch ball mount with dual ball from CURT is forged from steel and is built for durability and strength for dependable and safe towing. Built for varying applications, the adjustable ball can be raised or lowered for varying heights to ensure level towing. The dual ball has two sizes in one, preventing the need to carry more than one attachment. The highly versatile design works with multiple vehicle-trailer combinations, providing for a rise of up to 4" and a drop of up to 5-1/2", and the dual ball attachment can be used with other CURT WD shanks. Anti-rattle technology encourages a quiet ride providing reduced noise for passengers. The unique vibration resistant clip design prevents the need for two separate clips and installs snugly over both pins with just one. Forged from steel and with its durable carbide powder coat finish and chrome-plated trailer balls, the hitch is weather and corrosion resistant and made to endure years of use. The yellow zinc 2" ball is rated for 10,000 lbs. and the 2-5/16" ball is rated for 20,000 lbs. and is included with a limited lifetime warranty ? one year on parts and finish.

The CURT 45937 is an adjustable dual ball mount designed to connect a trailer to a vehicle's hitch receiver tube. It features an adjustable shank that allows you to set the correct ball height based on your trailer's coupler height, and includes a dual ball platform for towing flexibility. The product has a gross trailer weight capacity of 20,000 lbs and a tongue weight capacity of 2,000 lbs.
The CURT 45937 is designed to install into any standard trailer hitch receiver tube. However, you must verify that your vehicle has a hitch receiver and that the receiver tube size matches the shank. The manual does not specify receiver tube diameter or vehicle-specific compatibility. Contact CURT product support at 877-287-8634 or consult your vehicle's hitch documentation to confirm fitment.
No tools are required to install the CURT 45937. The installation is rated as Easy difficulty.
The CURT 45937 includes: (1) adjustable shank, (1) dual ball, (2) pins, and (1) clip. The hitch pin and clip that secure the shank to your vehicle's receiver tube are sold separately and must be purchased.
No. The hitch pin and clip required to secure the shank into your vehicle's receiver tube are sold separately. You must purchase these items before installation.
Level your trailer on level ground, then measure the distance from the bottom of the trailer tongue to the ground. This measurement is your required ball height. The CURT 45937 shank has multiple holes; find the hole closest to your measurement. The dual ball platform will be centered on that hole when installed. This ensures proper coupler alignment and safe towing.
Installation follows three steps: (1) Insert the adjustable shank into your vehicle's hitch receiver tube and secure it with a hitch pin and clip (sold separately). (2) Determine the correct ball height by measuring your trailer tongue height and finding the matching hole on the shank. (3) Slide the dual ball tongue onto the shank, align it with the proper holes, and insert both pins—secure all pins with the included clip.
Slide the tongue onto the shank and align it with the holes you determined in Step 2. Angle the tongue slightly upwards and press it toward the shank. Insert a pin into the top tongue hole first. To pin the bottom hole, apply downward force to the tongue and slide the second pin into place. Secure both pins with the included clip. Note: If using the highest mounting position, install the bottom pin first with the tongue angled downward, then apply upward force to install the second pin.
The CURT 45937 has a gross trailer weight (GTW) capacity of 20,000 lbs and a tongue weight (TW) capacity of 2,000 lbs. Never exceed these limits. Additionally, never exceed your vehicle manufacturer's recommended towing capacity, as the mount system ratings do not reflect the ratings of your vehicle's towing system.
No. You must use a hitch pin specifically designed for the CURT mount system. Using any other pin is a serious safety hazard and will void the warranty. If replacement pins are needed, they must be replaced with original factory mount pins (CURT# 45931).
No. Never hook up trailer safety chains to the mount system. Ensure that safety chains operate freely around the mount system and do not become entangled with it.
Never exceed your vehicle manufacturer's recommended towing capacity. The CURT 45937 ratings represent the product's capability, not your vehicle's towing system capacity. You must learn the ratings of all components in your towing system—hitch, receiver, shank, ball, trailer, brakes, and suspension—and never exceed the limits of the lowest-rated component.
Use mild automotive detergent to clean the product. Do not use dish detergent, abrasive cleaners, abrasive pads, wire brushes, or similar products, as these may damage the finish.
