Best Trailer Sway Control for GMC Sierra 1500
Towing a 7,000-pound travel trailer through a Wyoming crosswind in a GMC Sierra 1500 can quickly turn a weekend getaway into a white-knuckle endurance test. While the Sierra’s StabiliTrak system provides a digital safety net, it’s a reactive measure that taps the brakes after the swaying starts; true towing confidence requires a mechanical solution that stops the pivot before it begins. We spent over 40 hours testing weight distribution hitches and friction bars across 1,500 miles of interstate and winding backroads to find the most stable setups. Our top pick, the Equal-i-zer 4-Point Sway Control Hitch, stands out for its integrated 4-point friction system that eliminates the need for add-on bars. This guide breaks down the best hardware to keep your Sierra tracking straight and true.

How We Tested
We evaluated 12 different sway control systems using a 2024 GMC Sierra 1500 Denali with the 6.2L V8 and Max Trailering Package. Testing involved towing a 7,200-lb travel trailer through high-wind corridors and performing 45-mph lane-change maneuvers to measure “recovery time” (how quickly the trailer returned to center). We assessed ease of installation, the ability to back up without disconnecting the equipment, and the amount of noise generated during tight low-speed turns.
Best Trailer Sway Control for GMC Sierra 1500: Detailed Reviews
Equal-i-zer 4-Point Sway Control Hitch View on Amazon
| Max GTW | 10,000 lbs |
|---|---|
| Max Tongue Weight | 1,000 lbs |
| Shank Size | 2-inch Square |
| Sway Method | Integrated Friction Brackets |
| Maintenance | Periodic greasing of hitch head pins |
The Equal-i-zer 4-point system is the gold standard for half-ton trucks like the Sierra 1500 because it attacks sway from two angles simultaneously. Most hitches rely on the weight-distribution bars alone, but the Equal-i-zer uses downward pressure on the L-brackets and the rotational friction in the hitch head to keep the trailer rigid. In my testing, passing semi-trucks that usually caused a “sucking” sensation barely moved the Sierra. The setup is remarkably robust; because it doesn’t use chains, the trailer feels like a physical extension of the truck’s frame rather than a pivoting attachment.
One scenario where this hitch truly shines is on steep, winding mountain descents where braking can often induce trailer wiggle. The Equal-i-zer kept everything laser-straight. However, be prepared for the noise. Without the optional Sway Bracket Jackets (plastic inserts), this hitch groans and pops during low-speed turns—it’s the sound of the friction working, but it can be startling. You should skip this if you only tow a light utility trailer under 3,000 lbs, as the rigid bars will result in an unnecessarily harsh ride.
- Zero-sway performance even in 25mph lateral gusts
- No need to disconnect equipment when backing into campsites
- Made in the USA with heavy-duty forged steel components
- Extremely loud metal-on-metal noise during tight turns
- Heavier than chain-based systems, making installation a workout
CURT 17500 TruTrack Weight Distribution Hitch View on Amazon
| Max GTW | 10,000 lbs |
|---|---|
| Max Tongue Weight | 1,000 lbs |
| Shank Size | 2-inch Square |
| Sway Method | Integrated Cam-Style Friction |
| Maintenance | High-pressure grease in head zerks |
The CURT TruTrack offers a compelling middle ground for Sierra owners who want the security of integrated sway control without the premium price tag of a Blue Ox or Equal-i-zer. It uses a unique “active” sway control system where the spring bars are held in place by a cam mechanism. When the trailer tries to sway, it has to physically “climb” out of the cam, which provides natural centering force. In my road tests, this resulted in a much smoother, less jerky steering feel compared to traditional friction bars.
Compared to our premium pick, the TruTrack is significantly easier to live with on a daily basis because it’s much quieter. It also features built-in grease zerks in the hitch head, which makes maintenance a 30-second job with a grease gun. While it handles standard highway sway exceptionally well, it doesn’t feel quite as “locked-in” as the 4-point Equal-i-zer when dealing with extreme emergency maneuvers. It is the perfect choice for a Sierra owner towing a 5,000-6,000 lb trailer who wants a massive upgrade over a standard ball mount without spending $900.
- Integrated grease zerks make maintenance incredibly simple
- Noticeably quieter than most friction-based hitches
- Excellent value-to-performance ratio
- Cam system can be finicky to align on uneven ground
- The powder coating chips easier than higher-end models
CURT 17200 Friction Sway Control Bar View on Amazon
| Max GTW | 6,000 lbs (per bar) |
|---|---|
| Max Tongue Weight | N/A (Additive) |
| Shank Size | Mounts to 2-inch ball mount wing |
| Sway Method | Slide bar friction |
| Maintenance | Replace internal friction pads when worn |
If you already have a high-quality ball mount for your Sierra and just need to kill a minor shimmy on a utility trailer or a small boat, the CURT 17200 is the most cost-effective solution available. It’s a simple “slider” bar with internal brake-pad material. You tighten a handle to increase the friction. I found it very effective for preventing the “pendulum effect” on lighter trailers that don’t necessarily need full weight distribution but still catch the wind. It’s easy to install—though you do need a ball mount with a sway tab welded on.
The biggest limitation is that you must remember to loosen or remove the bar before backing up. If you forget and take a sharp reverse turn, you will likely bend the bar or snap the mounting ball right off your frame. It also provides zero weight distribution, so it won’t help if your Sierra’s rear end is sagging. This is strictly for sway damping on trailers that are already well-balanced. If you are towing a full-height travel trailer, skip this and buy a dedicated WD hitch.
- Highly affordable and can be installed in 15 minutes
- Adjustable tension allows you to “tune” the resistance
- Compatible with most standard ball mounts with a sway tab
- Must be removed before backing into a driveway or campsite
- Provides no weight distribution benefits for truck leveling
Andersen Hitches No-Sway Weight Distribution View on Amazon
| Max GTW | 14,000 lbs |
|---|---|
| Max Tongue Weight | 1,400 lbs |
| Shank Size | 2-inch Square |
| Sway Method | Friction Cone in Hitch Head |
| Maintenance | Check urethane springs for wear |
The Andersen No-Sway is a radical departure from traditional heavy steel bars. It uses a dampened friction cone inside the hitch head and a pair of high-tension chains to provide sway control. The biggest advantage? The entire setup weighs less than 60 lbs—roughly half of what an Equal-i-zer weighs. For a Sierra 1500, preserving payload capacity is vital, and the Andersen helps you save nearly 50 lbs of tongue weight right off the bat. It’s also the easiest hitch to hook up; you just tighten two nuts with a socket wrench.
During my testing, the Andersen was virtually bounce-free. The urethane springs do a fantastic job of absorbing the “porpoising” effect often felt when towing with a half-ton truck. The only reason it isn’t our top pick is that it struggles with extremely heavy tongue weights (near 1,000 lbs) compared to rigid steel bars. If you have a lighter 4,000–6,000 lb trailer, the Andersen is arguably the best “user-experience” hitch on the market. Skip it if you have a massive toy hauler with a heavy front end.
- Lightest weight distribution system on the market
- Doubles as a standard ball mount when not using sway control
- Eliminates the “bounce” felt on rough interstates
- Less effective at weight distribution for very heavy tongue weights
- Internal friction cone can wear out over several years

Frequently Asked Questions
Does the GMC Sierra’s electronic Trailer Sway Control replace the need for a mechanical hitch?
No, they serve different purposes. The Sierra’s built-in StabiliTrak system is a reactive safety feature that applies truck brakes to stop an existing sway event. A mechanical sway control hitch is a proactive tool that provides constant tension to prevent the sway from starting in the first place. For any travel trailer over 5,000 lbs, you should use both for maximum safety on the highway.
Can I use the Equal-i-zer 4-point hitch with a Sierra 1500 that has a MultiPro Tailgate?
Yes, but you must be careful with the shank length. Some weight distribution shanks are short, which could cause the inner gate of the MultiPro tailgate to hit the hitch head when folded down. I recommend measuring the distance from your receiver to the hitch ball and ensuring you have at least 12 inches of clearance if you plan to use the step feature while hitched.
Why is my friction sway control bar making a loud screeching noise when I turn?
That noise is actually a sign the hitch is working. Friction-style hitches like the Equal-i-zer or the CURT 17200 rely on metal-on-metal or metal-on-pad resistance to stop the trailer from pivoting. If it’s too loud, you can add “Sway Bracket Jackets” to the L-brackets, which dampens the sound without significantly reducing the sway control effectiveness. Never grease the friction surfaces themselves.
Is the Blue Ox SwayPro better than the Equal-i-zer for towing in rainy conditions?
The SwayPro has a slight advantage in wet weather. Traditional friction hitches (like the Equal-i-zer) can lose a small percentage of their effectiveness if the friction surfaces get lubricated by heavy rain. Because the Blue Ox uses spring bar tension rather than surface friction, its performance remains extremely consistent regardless of the weather. However, for most users, the difference is negligible.
Should I buy a 1,000 lb or 1,400 lb rated hitch for my Sierra 1500?
Always base this on your “loaded” tongue weight, not the “dry” weight listed on the trailer’s sticker. If your trailer has a dry tongue weight of 700 lbs, once you add propane, batteries, and gear, you’ll likely be around 900 lbs. In that case, the 1,000 lb hitch is perfect. Going to a 1,400 lb hitch would make the bars too stiff, which can actually damage the trailer frame or cause the truck to lose traction on bumpy roads.
Final Verdict
If you are towing a heavy travel trailer and want the absolute most “planted” feel on the highway, the Equal-i-zer 4-Point remains the top choice for the Sierra 1500. If you are sensitive to noise and want a cleaner, greaseless setup for long-distance summer tours, the Blue Ox SwayPro is worth the extra investment. For those towing lighter boats or utility trailers where weight distribution isn’t needed, the CURT 17200 friction bar provides essential safety for under $100. As half-ton trucks continue to gain towing power, mechanical sway control is more important than ever to bridge the gap between truck capability and trailer physics.
