The best anti-sway trailer hitch setup depends on whether you need a receiver-mounted tab, a trailer-frame ball, a replacement adapter, or a complete friction sway-control kit. The CURT 45820 is best for adding a sway-control mounting tab to a 2-inch receiver ball mount, while the CURT 17200 is best for shoppers seeking a sway-control kit. The other options provide mounting points or replacement adapters for compatible setups. Check receiver size and component fit before choosing.

CURT 45820 Sway Tab Ball Mount
Best for: Drivers who already have a compatible 2-inch receiver ball mount and need a mounting tab for a sway-control trailer ball. The CURT 45820 fits a 2-by-2-inch receiver tube opening and has a 1-inch hole for a trailer-ball shank.
It is a focused option for adding a sway-control attachment point rather than buying a complete sway-control system. Choose this if your existing setup needs the receiver-side tab and its dimensions match your equipment.
Limitation: The listed features describe a mounting tab, not a complete sway-control kit. Confirm that the ball shank and other components fit your system.
CURT 17201 Trailer-Mounted Sway Control Ball
Best for: Buyers who need a sway-control ball mounted directly to the trailer frame. This component is designed for attachment of CURT sway control model 17200 and is made of steel.
The listed package includes four self-tapping bolts, which are intended for installation. This product is a trailer-side attachment point, so it can suit a setup that already has a compatible receiver-side mounting point and sway-control unit.
Limitation: It is not a complete sway-control kit. Check the trailer-frame installation requirements and confirm compatibility with the sway-control equipment before purchase.
Single-Sided Anti-Sway Hitch Adapter
Best for: Owners of Class III or Class IV ball mounts with a 2-inch square shank who need a mounting pad for a friction sway control. The listing identifies this as a single-sided adapter, model 26003, for use with friction sway controls.
Choose this if the stated receiver-mount dimensions match your equipment and you need an adapter rather than a complete sway-control kit. Its single-sided opening is a key design detail to compare against your intended mounting arrangement.
Limitation: This adapter is intended to be used with a friction sway control; it does not provide the friction-control unit itself. Verify the mounting orientation and fit for your ball mount.
Replacement Sway Bar Hitch Adapter
Best for: Buyers replacing a 26003-style sway-control adapter for an RV, camper, or travel trailer. The listing describes it as a direct replacement for part number 26003 and specifies compatibility with Class III and Class IV 2-inch square ball mounts.
The adapter is made from thickened steel, according to the product features, and is intended for use with friction sway controls. It may be a better fit than a complete kit when the existing system already has its sway-control unit and only needs the adapter replaced.
Limitation: The listed use is limited to compatible 2-inch square ball mounts and friction sway-control systems. Confirm that 26003 is the part you need before ordering.
CURT 17200 Trailer Sway Control Kit
Best for: Buyers looking for a friction sway-control kit that helps limit lateral trailer movement. The listed fit includes most weight-distribution hitches or a CURT 45820 sway tab mount. The kit also includes a weld-on sway tab for use with most ball mounts.
Choose this if you need the control unit as well as a mounting solution, rather than an adapter alone. Its stated purpose is to reduce trailer sway by limiting side-to-side movement.
Limitation: The product features do not claim universal fit. Confirm your hitch configuration and mounting requirements before selecting it.
Buying Guide: How To Choose An Anti-Sway Hitch Mount
Do you need a mount, an adapter, or a complete kit?
A sway tab or adapter provides a place to attach a friction sway-control unit. A trailer-mounted ball provides the trailer-side connection point. A complete kit, such as the CURT 17200, includes the sway-control component. Identify which parts your current setup already has before buying.
Which receiver dimensions should you check?
Match the receiver opening and ball-mount shape to the product requirements. The CURT 45820 specifies a 2-by-2-inch receiver tube opening and a 1-inch hole for a trailer-ball shank. The listed adapters specify Class III or IV ball mounts with a 2-inch square profile.
Where does the sway-control connection attach?
Some components mount on the receiver-side ball mount, while the CURT 17201 attaches directly to the trailer frame. A friction sway-control system needs compatible connection points on both sides. Check the installation instructions and your equipment layout before purchasing.
What should you verify before ordering?
- Whether the product is a complete kit or only a mounting component.
- Whether its receiver size, ball-shank hole, and mounting style match your equipment.
- Whether the sway-control unit you own is designed to work with the selected mount.
- Whether trailer-frame attachment or other installation work is required.
