Complete 2-piece bundle kit containing all necessary components for your project. Professional-grade components designed for reliable performance and long-lasting durability.
If you own multiple trailers or frequently tow a variety of loads, you know how much time and money are spent tailoring your towing system to each and every individual trailer. There is nothing more inconvenient than switching back and forth between a few different ball mounts and trying to remember which mount fits with which trailer. A CURT adjustable ball mount is your multipurpose towing solution. Its key feature is its adjustable design that takes the form of an adjustable channel-style assembly. It uses a series of holes to allow the ball mount platform to be vertically adjusted and allow for significant flexibility in drop and rise. With a variable ball height, it can easily accommodate different coupler heights and multiple trailers. This particular adjustable channel-style ball mount features a gross trailer weight capacity of 6,000 lbs. Unlike other adjustable ball mounts that have fixed trailer balls, this one comes with a trailer ball platform with a 1" ball hole, allowing it to readily accept the trailer ball of your choice. It offers a maximum drop of 6-3/4" and a maximum rise of 5-1/4". It also has a built-in anti-rattle design to eliminate chucking noises and offers two length options of 11" and 12".All CURT adjustable ball mounts come with a 2" x 2" shank and are made with sturdy steel construction. For long-lasting rust, scratch and UV resistance, this one also comes with our durable black carbide powder coat finish to give you peace of mind for the road ahead.

CURT Switch Ball trailer balls are a breakthrough in trailer ball technology. As a result of CURT innovation and engineering genius, Switch Balls offer the ultimate in convenience and reliability for a variety of light-duty and medium-duty towing applications. Essentially, a CURT Switch Ball is a trailer ball shank with a removable head. With its exclusive J-groove design, the Switch Ball trailer ball allows different heads or ball sizes to be places on the shank for accommodating different coupler sizes. This means there is no need to switch between ball mounts or even to own a second ball mount to fit an additional trailer. When you need to make the switch, simply twist the Switch Ball head, lift it off and twist on another. The J-groove ensures a solid hold on your trailer, while still allowing for easy removal of the trailer ball without tools or pins. This CURT Switch Ball trailer ball set comes with two ball attachments. Ball 1 features a ball diameter of 1-7/8" and ball capacity of 3,500 lbs. Ball 2 has a 2" ball diameter and a ball capacity of 6,000 lbs. Ball 3 has a 2-5/16" diameter and a ball capacity of 8,000 lbs. The shank measures 2-1/4" long and 1" in diameter. We construct these interchangeable hitch balls from premium-grade steel for strength and give them a bright nickel-chrome finish for a long life. To ensure your safety and provide you with a tow ball you can depend on, CURT Switch Balls are independently tested in accordance with SAE J684.

Call 888-634-9494The CURT 45901 is an adjustable channel ball mount designed to install into a vehicle's trailer hitch. It allows you to adjust the height of the ball mount platform to match your trailer coupler height. The system uses pins and clips to secure the ball mount at the desired height and includes an anti-rattle set screw to eliminate noise.
You must install a trailer ball with a 1" shank and a 6,000 lbs. rating into the ball mount platform. The ball must be installed to the manufacturer's specifications. If you are not familiar with this process or do not have the proper tools, you must have the ball installed by an experienced dealer capable of tightening and checking the torque of the trailer ball and nut.
The CURT 45901 includes an adjustable channel-mount, hitch pin and clip, height-adjustment pins with clips, and an anti-rattle set screw. The trailer ball is not included and must be purchased separately. Replacement pins must be original factory channel-mount pins (CURT# 45915).
Installation of the channel-mount itself into the vehicle hitch is straightforward and can be done by most users. However, if you are not familiar with installing a trailer ball and do not have the proper tools to tighten and check the torque of the trailer ball and nut, you must have the ball installed by an experienced dealer. The ball must be installed to the manufacturer's specifications for safety.
1. Install the adjustable channel-mount into the trailer hitch of the vehicle and secure it with the provided hitch pin and clip. Always secure the hitch pin with a clip unless a locking device is being used. 2. Determine the height at which you need to install the ball mount into the channel-mount. 3. Raise or lower the ball mount to the desired height and insert the supplied pins through the holes that line up with the holes in the channel-mount. 4. Secure the pins with the provided clips. 5. Tighten the anti-rattle set screw tightly into the channel-mount to eliminate noise.
Determine the height at which you need to install the ball mount into the channel-mount to match your trailer coupler. Raise or lower the ball mount to the desired height and insert the supplied pins through the holes that line up with the holes in the channel-mount. Secure the pins with the provided clips. The supplied pins are specifically engineered for the channel-mount system.
The anti-rattle set screw is tightened into the channel-mount to eliminate noise and rattle between the channel-mount and the ball mount platform. Use of the set screw is not needed for safety; it is only to eliminate possible rattle. Tighten it tightly after the ball mount is set to the correct height and secured with pins and clips.
No. The supplied pins are specifically engineered for the channel-mount system. If replacement pins are needed, they must be replaced with original factory channel-mount pins (CURT# 45915). Use of any pin other than that of the channel-mount system manufacturer could be a serious safety hazard and will void the warranty.
The CURT 45901 is rated for a trailer ball with a 6,000 lbs. rating. However, you must never exceed your vehicle manufacturer's recommended towing capacity or the trailer hitch capacity, whichever is less. The ratings of the channel-mount system represent the capability of the product and in no way reflect the ratings or capacity of the towing system it is being used with. Always check your vehicle owner's manual to determine your vehicle's tow rating and never exceed the limits of the lowest-rated component in your towing system.
No. Never hook up trailer safety chains to the channel-mount system. Ensure that the safety chains operate freely around the channel-mount system and do not become entangled in the channel-mount system.
Prior to towing, check to make sure the pins are secured into place with clips. Verify that the safety chains operate freely around the channel-mount system and do not become entangled. Ensure that the ball mount is set to the correct height and that the anti-rattle set screw is tightened. Never exceed your vehicle's towing capacity or the trailer hitch capacity, whichever is less.
The CURT 45901 is designed to install into any vehicle with a standard trailer hitch receiver. Consult your vehicle owner's manual to confirm your vehicle has a trailer hitch and to determine your vehicle's towing capacity.
No. The trailer ball is not included. You must purchase a trailer ball with a 1" shank and 6,000 lbs. rating separately and install it into the ball mount platform.
No drilling is required. The CURT 45901 installs into your vehicle's existing trailer hitch receiver using the provided hitch pin and clip.
The CURT 45901 accommodates a trailer ball rated for 6,000 lbs. However, you must never exceed your vehicle manufacturer's towing capacity or the trailer hitch capacity, whichever is less. Check your vehicle owner's manual for your specific towing limit.
Yes. The CURT 45901 is adjustable. Raise or lower the ball mount to match your trailer coupler height by inserting the supplied pins through the aligned holes and securing them with clips.
No. Never hook safety chains to the channel-mount system. Ensure safety chains operate freely around the system and do not become entangled.
