6 Best 4 Point Sway Control Hitch in 2026: A Practical RV Guide
Four-point sway control hitches built into weight distribution: Equal-i-zer, CURT TruTrack and Nilight models compared by rating, shank and fit.
By Hardcastle's RV Editors
10 min read6 products evaluated
A four-point hitch resists sway at several contact points built into the head and frame brackets, so there is no separate bolt-on sway bar to set up. It is a weight distribution hitch first, which means it also levels the tow vehicle, and that shapes every buying decision below.
The six picks are ordered by how clearly each listing states its ratings and what comes in the box. Because tongue weight rating decides whether a hitch rides smoothly or stiffly, each entry says plainly where the rating is stated and where you should confirm it.

- Sway design
- We separated friction-point designs from spring and cam designs.

What Matters Before You Choose a 4 Point Sway Control Hitch
Key buying criteria so you get the right fit the first time.
Tongue weight rating
Tongue weight is the downward force on the hitch ball, typically 10 to 15 percent of the loaded trailer weight. A hitch rated far above it rides stiff and transfers road shock into the truck, while one rated below it is unsafe. Weigh your loaded trailer tongue and choose a rating that sits just above it.
Four-point versus spring and cam
Equal-i-zer designs resist sway through four friction points, while CURT TruTrack uses a spring and cam system as well. Friction designs need no extra bar, but they do need the bracket in the right place. Read the listing for the design name and bracket placement.
Shank included or not
The shank sets drop or rise and receiver size, and some kits leave it out. Equal-i-zer 1400 and 1000 list the shank as not included, which adds cost and a measurement step. Check the title for does not include or includes shank wording.
Surge brake and trailer type
Boat and some utility trailers use surge brakes, and weight distribution brackets can interfere with them. The Equal-i-zer 1000 lists compatibility with surge brake trailers. Look for that wording if your trailer has surge brakes.
Setup effort and adjustment
Weight distribution hitches need adjusting for every trailer and load, using the chain link or bar tension. A fixed bracket design gives repeatable results, while chain designs vary. Check how the listing describes tensioning and read the maker's manual before towing.
Sway control does not fix a bad load
A hitch resists sway but cannot cure a trailer with too little tongue weight. Loading too far back lowers tongue weight below 10 percent and invites sway. Weigh the tongue and shift cargo forward before you blame the hitch.
Match a 4 Point Sway Control Hitch to Your RV
By Trailer Tongue Weight
| Your situation | Recommended pick | Why |
|---|---|---|
| Around 900 lb tongue weight | Equal-i-zer 1000 | 1,000 lb rating with headroom. |
| Around 1,300 lb tongue weight | Equal-i-zer 1400 | 1,400 lb tongue rating. |
| Above 1,400 lb tongue weight | Equal-i-zer 1600 | 1,600 lb tongue rating, shank included. |
| Light travel trailer, tight budget | Nilight 4-Point | Shank and ball included in the kit. |
| Want a spring and cam design | CURT 17500 | Spring and cam, 10K in the title. |

By Budget
| Budget | Recommended pick |
|---|---|
| $300 to $560 | Nilight 4-Point or Equal-i-zer 1000 |
| $590 to $610 | CURT 17499 or CURT 17500 |
| $680 to $750 | Equal-i-zer 1400 or Equal-i-zer 1600 |
Friction Points vs Spring and Cam
- Friction points
- Resists sway by friction at four contact points on the head and frame brackets. Equal-i-zer 1000, Equal-i-zer 1400, Equal-i-zer 1600 and Nilight 4-Point fit here.
- Spring and cam
- Uses cams and spring bars with fixed brackets instead of friction alone. CURT 17500 and CURT 17499 fit here.
Most buyers should default to the Equal-i-zer 1000 or a larger Equal-i-zer sized to their tongue weight, and choose a CURT if the cam design appeals.
By Install Preference
| Preference | Recommended pick |
|---|---|
| Shank already included | Equal-i-zer 1600 |
| Fixed adjustable brackets | CURT 17500 |
| Lowest cost kit with shank and ball | Nilight 4-Point |
| Surge brake trailer | Equal-i-zer 1000 |
For a Mid-Size Travel Trailer Specifically
- Look for
- A tongue weight rating just above your loaded tongue weight, so the bars flex properly, as the Equal-i-zer 1000 rating does for a 900 lb tongue.
- In this comparison
- The Equal-i-zer 1000 rates 1,000 lb tongue weight and the Equal-i-zer 1400 rates 1,400 lb, so the 1000 is the closer fit for most mid-size trailers.
When to Spend More
- Spend more if
- Spend more on the Equal-i-zer 1600 if the trailer is heavy and you want the shank included, or the Equal-i-zer 1400 for a tongue weight above 1,000 lb.
- Save if
- Save with the Nilight 4-Point on a light trailer, or the CURT 17499 once you have confirmed its ratings with CURT.
Before You Bring One Home
Is a 4-point hitch the same as a weight distribution hitch?
Yes, in these listings the sway control is built into a weight distribution hitch. The Equal-i-zer 1000 describes both functions, while a friction bar only resists sway.
What mistake do buyers make with ratings?
Buying the largest rating for safety. A 1,600 lb tongue weight hitch under a 900 lb tongue rides stiffer, so pick a rating just above your actual tongue weight.
Is the Equal-i-zer 1000 worth it over the Nilight 4-Point?
For trailers near 10,000 lb, yes. The Equal-i-zer states trailer and tongue ratings and surge brake compatibility, while the Nilight is cheaper but lists lower ratings.
How do I set up a 4-point hitch?
Level the trailer, attach the head and set the spring bar tension with the chain link or bracket, then position the sway bracket per the manual. Recheck the front fender height after loading.
How do I maintain it?
Lubricate the pivot points the maker names and check bolts and brackets for loosening every few trips. Store it clean and dry to prevent rust.
