6 Best Friction Sway Control Hitch in 2026: A Practical RV Guide
Friction sway control starts with the right mounting parts: ball mount adapters and a sway ball compared, with a clear note on what each one is and is not.
By Hardcastle's RV Editors
10 min read6 products evaluated
A friction sway bar is a sliding bar that links the ball mount to the trailer frame and resists sideways motion. Every pick below is a mounting part for that system, either an adapter plate for the ball mount or a replacement sway ball, and none of them is the friction bar itself.
That distinction drives the ranking. Each entry says what the part attaches to, what it needs from you, and the checks to make before you order, since a part that fits the wrong ball mount is the most common mistake in this category.

How We Built This Shortlist
Each pick was assessed across 5 criteria weighted for real-world use.
- Part type
- We separated adapter plates from replacement sway balls, and noted that none of the picks is a friction bar.
- Fit statement
- We compared which listings name Class III and IV 2 inch square ball mounts and which give hole dimensions.
- Install effort
- We checked whether each listing describes a no-weld, bolt-on install.
- Corrosion protection
- We noted stated coatings and finishes.
- Side options
- We compared one-sided and two-sided mounting plates.
What Matters Before You Choose a Friction Sway Control Hitch
Key buying criteria so you get the right fit the first time.
Adapter versus the bar
A friction sway bar is the slide bar and bracket that resists sway. An adapter plate or sway ball only gives that bar a place to attach. Read the title for the words adapter, plate or ball, and buy the bar separately.
Ball mount compatibility
These plates fit Class III and IV 2 inch square ball mounts. Mounts with other shank sizes or odd geometries may not take them. Check your ball mount class and the stud diameter before ordering.
One side or two
A two-sided plate lets the bar attach on either side of the ball mount, while a single-sided plate fixes you to one side. Two-sided plates cost slightly more. Look at your trailer's bracket position before choosing.
Hole sizes
The ball stud must pass through the main hole, and a mismatch means the plate will not seat. SHUJUKU lists a 1.02 inch main hole and a 0.66 inch secondary hole. Compare the numbers with your ball stud.
Finish and rust
Sway hardware lives near the hitch ball, where it gets road spray. A black anti-rust layer or chrome plating slows corrosion. Look for a named coating on the listing.
When to take it off
Friction sway bars resist motion both ways, so they should be loosened or removed when backing up and on slick roads. A sway ball makes that quick on some systems. Read the bar maker's guidance on removal before towing.

Plate vs Ball
- Adapter plate
- A flat steel plate that sits on the ball stud and gives the bar a mount. JIANBENKJ Two-Sided, SHUJUKU Two-Sided, JIANBENKJ 26003, Shimeyao 26003 and SHUJUKU 26003 fit here.
- Sway ball
- A small ball that the sway bar's socket snaps onto. CURT 40093 is the one sway ball here.

| Stated anti-rust coating | SHUJUKU 26003 |

For a Travel Trailer Owner Adding a Friction Bar Specifically
- Look for
- A plate that fits your Class III or IV 2 inch ball mount, with a way to attach on the side your trailer bracket sits, such as the JIANBENKJ Two-Sided.
- In this comparison
- The JIANBENKJ Two-Sided and SHUJUKU Two-Sided give both mounting sides, while the single-sided plates fix you to one side.
When to Spend More
- Spend more if
- Spend more on the JIANBENKJ Two-Sided for the flexibility of either side, or the SHUJUKU 26003 if a stated rust coat matters.
- Save if
- Save with the Shimeyao 26003, which is the cheapest plate and lists a clear install, or the JIANBENKJ 26003 as a plain replacement.
Before You Bring One Home
Is a friction sway control hitch the same as a sway adapter?
No. The adapter plates and ball in this guide only mount a friction bar. The bar itself is a separate part, so check that you are buying what you need.
What mistake do shoppers make?
Ordering a plate without checking the ball mount class. The listings say Class III and IV 2 inch square ball mounts, so confirm yours before buying.
Is the JIANBENKJ Two-Sided worth it over the Shimeyao 26003?
If you may mount the bar on either side, yes. The Shimeyao 26003 costs less but gives one mounting side.
How do I install an adapter plate?
Remove the ball, slide the plate onto the ball stud, and tighten the ball fully, as the Shimeyao 26003 listing describes. No welding is needed.
Should I leave a friction bar on all the time?
Not on slick roads or when backing up. Friction bars resist motion in both directions, so loosen or remove them in those cases, following the bar maker's instructions.
