CURT 17200 Sway Control Kit
See how a bolt-on friction sway kit attaches beside a weight-distribution setup — the classic add-on bar approach.
Watch on YouTube →Do I Need a Sway Bar (Canada)
Wondering if you need a sway bar for towing in Canada? Start with tongue weight and trailer shape, not a scary internet rule. Light tongue weight, a tall box, and a long overhang make side-to-side fishtail more likely on prairie gusts and highway pass-bys. This page is the practical decision guide. For deeper product and setup detail, use our full trailer sway control guide.

CURT True Course overview
How True Course senses out-of-range trailer motion and intervenes without relying only on a friction bar.
Watch on YouTube →Stop trailer sway in its tracks
A quick look at stopping sway before it builds — useful context when you compare electronic versus mechanical control.
Watch on YouTube →TruTrack with integrated sway
TruTrack builds sway resistance into the weight-distribution hitch so you are not always bolting on a separate friction bar.
Watch on YouTube →When sway gets worse
Trailer sway is the side-to-side fishtail that starts small and can grow fast. Tongue weight that sits too light is the usual villain. Cargo stacked far aft, a empty front trunk, or a steep tongue angle after a lift all unload the coupler and invite yaw. Read tongue weight explained if you have never put a scale under the coupler.
Trailer shape matters next. A tall enclosed cargo box, a travel trailer with a big frontal area, or a long rear overhang acts like a sail when a transport passes you on Highway 401 or a prairie crosswind hits. Short utility trailers with a low load and honest tongue weight rarely need a sway bar. Tall, long, or lightly loaded trailers complain sooner.
Speed, soft tires, and an unlevel ball mount make the same trailer feel worse. Fix those basics before you buy hardware. We are not inventing a legal cutoff such as “always buy sway control above X pounds.” Your trailer manual, the tow-vehicle door sticker, and how the combination feels on a calm day are the real decision inputs.
A simple yes, maybe, or not-yet path
Often yes
Tall or long trailers
Travel trailers, tall cargo boxes, and setups that already want weight distribution usually benefit from sway control of some kind.
Maybe
Borderline tongue weight
If the scale number is soft, or the trailer feels nervous only in gusts, fix load and tire pressure first, then reconsider a kit.
Often not yet
Short and heavy on the tongue
A low utility trailer with solid tongue weight and calm manners rarely needs a sway bar. Do not buy hardware for a problem you do not have.

Weight distribution first
Rear squat on the tow vehicle is a weight-distribution cue. See when do I need weight distribution before you chase sway alone.

| Question | What to do |
|---|---|
| Is tongue weight honest? | Scale it. Fix cargo before buying a sway bar. |
| Is the trailer tall or long? | Expect gust sensitivity. Sway control is more often worth it. |
| Does the tow vehicle squat? | Look at weight distribution first, then sway hardware. |
| Do you already own a WD hitch? | A friction kit such as 17200 may bolt on. Read the full sway guide for fit details. |
| Want one integrated unit? | Consider a WD hitch that includes sway control, such as live CURT 17050 on this store. |
What this page will not do
We will not invent a legal Canadian cutoff that says every trailer over a made-up weight must have a sway bar. Provincial rules, trailer manuals, and hitch ratings still win. We also will not pretend a sway bar fixes bad tire pressure, a worn coupler, or cargo piled on the rear bumper.
For friction versus integrated systems, install notes, and Canada highway tips, keep reading on the full trailer sway control guide. For leveling spring bars and squat, use the weight distribution hitch guide.
