Features to know about

Smooth, Level Ride: Patented True Motion-Dampening Design

Towing doesn’t have to feel like a tug-of-war between your trailer and your tow vehicle. This system uses Andersen’s patented True Motion-Dampening design with lightweight urethane tension springs that keep everything level and stable. The springs distribute weight evenly over both axles, so instead of your trailer pushing down on the back end, the whole setup rides balanced and controlled. You get less bounce, less sway, and a smoother towing experience overall.

Quieter Trips Without the Metal Clank: Urethane Springs Replace Heavy Bars

Old-school spring bars can be noisy and awkward to wrestle into place. This design eliminates those heavy metal bars, replacing them with compact urethane springs that do the same job without the hassle. With no metal-on-metal contact, you won’t hear the clank and grind that come from traditional setups. It’s a clean, quiet ride that feels solid without the noise.

Built-In Sway Control That Works Automatically: Constant Tension Keeps You Straight

Crosswinds and passing trucks can make even confident drivers uneasy, but this system fights sway from the start. Once installed and adjusted, the urethane springs stay under constant tension, working together to push your trailer back to center. Friction material around the ball shank resists side-to-side movement that causes sway, so you don’t need an extra sway bar or add-on device. The ball and tension plate rotate freely with the coupler, so turning stays smooth and controlled.

Tight Maneuvers Made Easy: Back Up Without Disconnecting

No more pulling over to unhook before reversing or making a sharp turn. The hitch design lets you drive in reverse while the system stays fully connected. That’s a big plus when backing into camp spots or driveways—you keep the same stability and sway control whether you’re moving forward or backward.

Strong, Simple, and Ready to Tow: 14,000 lbs GTW and 1,400 lbs TW Rating

This setup is built for serious towing with a 14,000-lb gross towing weight and 1,400-lb tongue weight capacity. It fits 2" x 2" trailer hitch receivers rated for use with a weight-distribution system and allows up to a 4" drop. The kit includes the shank, 2-5/16" ball, urethane springs, chains, brackets, and the wrench needed for adjustment. Once in place, turning the tensioning nuts on each side is all it takes to fine-tune your setup before hitting the road.

Easy to put trailer on.
by:
light weight but great control over sway and bounce, returned my canyon to level when towing my 25’ Rpod 205 and made for a stable tow at highway speeds with a 12% tougue at weight with my Truck’s 1480 payload rating.

Fit and functions perfectly. Great customer service.

The Andersen WDH is the hitch recommended by Oliver Trailers for 1/2 ton pickups, which I recently acquired both of. A friend and I installed it, which required additional 3/8" chain to what was supplied in the Andersen kit. The 24' Olver LE II trailer (5500 dry weight) pulls beautifully with the Andersen hitch. no sway in winds or effect by passing trucks, I can easily go 75mph if I chose to do so. The other big advantage of this hitch is its light weight which positively benefits the tongue weight calc. The only challenge I had initially was getting the hitch onto the hitch ball structure. The key is to sufficiently relax the chains, using the nuts at the end of the chain mechanism, which is quite easy to do with the supplied socket. Highly recommend the Andersen WDH, great design.
by:
Reduced porpoising and eliminated sway! Much better ride than the Weigh Safe WDH I was using. Also the components are very light and easy to use compared with all the competitors that have spring bars. I installed Timbrens after driving for over 1000 miles, and that totally eliminated the remaining porpoising, Directions should be re-written to eliminate the need for the additional insert, also more advice on fine-tuning for a better ride and adjusting for "squat" would be helpful.

Thanks for sharing such a detailed review! It’s great to hear the Andersen made such a noticeable improvement in sway and porpoising, especially compared with your previous WDH. Your feedback on the instructions and fine-tuning is helpful too. For reducing squat, the Andersen can generally be fine-tuned by increasing chain tension evenly on both sides in small increments. Using the tongue jack to take some load off the system makes those adjustments easier. The goal is proper weight transfer to the front axle rather than eliminating rear squat completely.

by:
I really like how lite it is! No more 90lb ball to carry around, tows beautifully no sway at all.
by:
I had issues with sway control from the minute I purchased this unit. Andersen customer service was fantastic. They assisted me thru troubleshooting. After 8 months of trying I requested a replacement or refund they informed me I had to go thru the company I purchased it from. I was certain that e-trailer would deny my request due to the length of time. They stepped up and spoke with Andersen and I was able to get a refund anthough I have to pay for return shipping as per the warranty. Great job e-trailer.
by:
My trailer setup is not standard (big lithium batteries on the tongue inside a fabricated box). The only place I could get the brackets required 6 links to be cut off. I’m not happy about this but the trailer is under 4000 lbs so I am hoping it will still have usable weight distribution. I guess I should not have made this purchase.
by:
High quality, well packaged. Etrailer is great to work with.
by:
From shipping to setup and hookup to towing the entire experience has been excellent! This was very easy to install, it is easy to hookup when towing, it doesn't make that awfull noise, and there has been no sway or sag in weight distribution. It shipped fast, the communication and help offered was outstanding, and the instructions that came with the item were more than enough.
by:
Great quality, easy setup with clear instructions, worked excellent.

Great service, quick shipping.
by:
Great product. fits perfectly and the shipping was incredibly fast.
by:
The package arrived quickly & in good condition. I am installing it this weekend, but it looks like everything included in the box is in good condition.
by:
Easier to use than the previous system I had installed in 2018 on the Oliver travel trailer.
by:
Product is well made. Getting the position of the brackets on the trailer A-frame is tricky. I had to move them when I noted that there is a limited amount of threads on the chain bolts so too loose or too tight can't be corrected if the brackets are over an inch one way or the other.
by:
Great price and incredibly fast shipping.
by:
Install instructions and you tube video made the process easy. Hitch worked as advertised on a test drive. Time will tell after some long distance tows. I am happy with the lighter weight than other wdhs.
by:
Still sways more than I would like in the wake of other vehicles.

  • Best Weight Distribution System For 2021 Jayco Jayflight 33RBTS
    Hello Domonic, thanks for reaching out. The correct weight distribution (WD) hitch for your 2021 Jayco Jayflight 33RBTS will depend on the loaded tongue weight. According to the online specs the dry hitch weight is 1,045 lbs but this does not account for fuel, batteries or other cargo. Ideally the tongue weight will be around 15% of the total weight, but that kind of depends on how you have things loaded. So most likely your loaded tongue weight will be around 1,400-1,600 lbs. I do suggest...

  • What is Weight of Blue Ox and Andersen Weight Distribution Systems
    Hey John, the weight of the Andersen weight distribution # AM3350 is 53 lbs and the Blue Ox # BXW1000 weighs 95 lbs. Worth mentioning is that the Blue Ox is going to do a much better job of actually redistributing the tongue weight to the tow vehicle over the Andersen. Are you worried about exceeding towing capacities?

    Hey Oscar! Yes, the Andersen # AM3350 (same as 3340) will be enough for your setup. With the way their system works this won't be overkill for your travel trailer. I would stick with their recommendation. Any big trips coming up with the Brinley?

  • What Andersen Weight Distribution Hitch Is Best for a 7,000lb Trailer?
    Hey Morgan, For your 7,000lb Lance Evolve trailer, I suggest using the Andersen Weight Distribution Hitch w/Sway Control with 4" Drop/Rise part # AN88VR or the Andersen Weight Distribution Hitch w/Sway Control with 6" Drop/Rise part # AN28VR. The Andersen Weight Distribution Hitch part # AN3350 you were looking at is rated too highly for the weight of your trailer. Because it's rated for trailers that weigh up to 14,000lbs, it would have a harsher ride with your lighter trailer because...
