The best sway control ball mount depends on whether you need a trailer-side attachment, a hitch-side mounting tab, or a replacement adapter. The CURT 17201 is best for adding a sway-control ball to a trailer frame, while the CURT 45820 fits a 2-inch receiver and provides a ball-mounting tab. A replacement adapter and two broader hitch options round out the comparison. Check your sway-control system’s instructions and hitch specifications before choosing.

CURT 17201 Trailer-Mounted Sway Control Ball
Best for: A setup that needs a sway-control ball mounted directly to the trailer frame. This component is designed for attachment of CURT sway control model 17200, making it a focused option rather than a complete sway-control system.
Its listed features include strong steel construction and four self-tapping bolts for installation. Choose this if your sway-control arrangement calls for a trailer-side ball and the product’s placement matches the system instructions.
Limitation: This is a trailer-mounted ball, not a complete hitch or sway-control device. The listing identifies it for use with model 17200.
CURT 45820 Sway Tab Ball Mount
Best for: Towing setups using a hitch with a 2-inch by 2-inch receiver opening that need a tab for a sway-control trailer ball. The mount has a 1-inch hole to accept a trailer ball shank.
This is the more relevant choice when the required mounting point is at the vehicle’s hitch rather than on the trailer frame. Compare its receiver size and ball-shank hole with your equipment before ordering.
Limitation: The listed features describe a mounting tab, not an included sway-control system or trailer ball.
Anti-Sway Trailer Hitch Ball Mount Adapter
Best for: Buyers seeking a replacement friction-sway adapter listed as a substitute for part 26003. The product description says it fits Class III and Class IV 2-inch square ball mounts and is intended for use with friction sway controls.
The adapter is made from thickened steel, according to the listing, and is described as a mounting pad for standard ball mounts. It may suit a setup where an adapter is needed to position a sway-control attachment for a different vehicle height.
Limitation: Confirm the replacement part number and mounting arrangement against your existing equipment. The description does not establish compatibility with every sway-control system.
CURT 45042 Loaded Ball Mount
Best for: Buyers who need a standard loaded ball mount rather than a dedicated sway-control tab or adapter. The product name specifies a Class III 2-inch mount with a 2-5/16-inch ball.
Consider it only when those ball-mount specifications suit the towing setup and a separate sway-control mounting solution is not required. This product is included as a broader hitch component, not as a direct replacement for the CURT 17201 or 45820.
Limitation: The supplied product information does not list dedicated sway-control features, so do not assume it provides a sway-control attachment.
VEVOR Sway Control Weight Distribution Hitch
Best for: Buyers comparing a full weight-distribution hitch kit instead of a single sway-control ball mount. Listed features include a 1,500-pound capacity, 2-inch solid steel shank, 2-5/16-inch alloy steel ball, and powder-coated load-leveling design.
This is a different category from a small mounting tab or trailer-frame ball. Choose it if you are shopping for a weight-distribution hitch package and its stated capacity and components match your towing requirements.
Limitation: The listing’s capacity should not be treated as a substitute for checking the vehicle, trailer, and hitch ratings. The supplied details do not specify a separate sway-control ball mount.
Buying Guide: How To Choose A Sway Control Ball Mount
Does the ball mount attach to the trailer or vehicle?
First identify where your sway-control system requires its ball. The CURT 17201 attaches directly to the trailer frame. The CURT 45820 provides a tab for a sway-control ball at a 2-inch receiver hitch. These parts serve different mounting locations and are not interchangeable just because both support sway-control equipment.
Which dimensions and replacement part should you verify?
Match receiver opening, ball-shank hole, and adapter part number to your existing components. The CURT 45820 lists a 2-inch by 2-inch receiver fit and 1-inch hole. The replacement adapter is described for Class III and IV 2-inch square ball mounts and references part 26003. Verify measurements and system instructions before purchase.
Do you need a mount, adapter, or complete hitch?
- Mounting ball: Choose a trailer-side ball when the sway-control system calls for that attachment point.
- Tab or adapter: Choose a hitch-side component when the required mounting location or replacement part calls for one.
- Loaded ball mount or weight-distribution hitch: These are broader hitch components. Confirm they include the sway-control features your setup actually needs.
What capacity information matters?
Compare the ratings of the tow vehicle, receiver, ball mount, and trailer. Do not rely on one component’s stated capacity to establish the capacity of the full towing system. Follow the equipment manufacturers’ installation and towing instructions.
