Features to know about

Dial In the Perfect Balance Every Time: Built-In Tongue Weight Scale with App Guidance

Balancing your trailer can be a guessing game, but this hitch turns it into an exact science. The Weigh Safe True Tow includes a built-in tongue weight scale that shows your real-time load right on the hitch. Just hook up, check the reading, and make sure you’re in that 10–15% sweet spot of your gross towing weight. If it’s off, open the companion app, input your setup’s details, and it tells you precisely what your distributed tongue weight should be. Then use the lead screw on the hitch head to dial it in until the scale matches. No trial and error, just a perfectly balanced setup ready for the road.

Smooth, Controlled Towing When Conditions Change: Integrated Sway Control and Trunnion Bars

Strong crosswinds, passing semis, and uneven roads can make a trailer feel less settled behind you. True Tow uses built-in tension and friction points to help resist side-to-side movement, while the trunnion-style spring bars distribute trailer weight across your tow vehicle and trailer axles. Together, they help your setup stay more level and your trailer track more steadily when road and traffic conditions change.

Backing Up with the Hitch Attached: What to Know Before You Turn

Weigh Safe does not recommend backing with the spring arms attached, especially when you are dealing with a steep driveway, a sharp turn, or another significant change in grade. Never tow or back up with the spring arms attached if the angle between your tow vehicle and trailer centerlines exceeds 60 degrees. If you need to make a sharper turn while backing, disconnect the spring arms first. Exceeding that 60-degree limit can damage the hitch, cause system failure, and void the warranty.

Built to Handle Heavy Loads with Confidence: 18,500 lbs GTW and 1,850 lbs TW Capacity

This hitch is made for serious weight. With a maximum gross towing weight of 18,500 lbs and a tongue weight rating of 1,850 lbs, it’s ready for demanding towing setups. The 2-5/16" stainless steel hitch ball resists rust, while the high-strength steel shank fits 2-1/2" receivers designed for weight distribution systems. Every component feels solid, with smooth tolerances and tight fitment that make the whole system feel secure and precise.

Simplifies Setup and Everyday Use: Easy Adjustments and Practical Design

Getting the system ready is straightforward—hook up, check the scale, connect the arms, and adjust the lead screw until your target weight is set. The hitch includes a lock to secure the shank, while top-mount brackets fit trailer frames up to 6" tall (with an option for 8" using WS89RR, sold separately). With a 6" maximum drop, 7" rise, and 1-1/4" incremental height adjustment, it’s easy to fine-tune your setup for the perfect towing height. The True Tow takes the hassle out of weight distribution so you can focus on the drive, not the gear.

Pair the built-in tongue weight scale on this hitch with the easy-to-use instructional app, and get the perfect towing setup. We love how Weigh Safe makes it easy to get totally balanced, but we love the smooth ride this hitch offers even more.

I just received the Weigh Safe Heavyweight distribution hitch. The one quite heavy as can be imagined package arrived in perfect condition. After unboxing the hitch, I’m impressed with the quality and workmanship. I can not report on the performance at this time, however the installation manual and user guide is quite clear to understand and follow. Also etrailer customer service is fantastic and I recommend purchasing anything through them as I’m a repeat customer.



by:

Installed according to printed instructions and videos. Downloaded app and this thing will not keep my trailer from swaying. I was so hopeful but now regret I spent $1070 on this hitch and I can’t keep my trailer between the lines when there is any wind.  I have only used the hitch once and now going to have to buy a different hitch.



by:

This is the best weight distribution hitch. The instructions are very detailed plus the downloadable app makes it easy to dial in the proper weight distribution across the trailer and truck. After installing mine, both the camper and tow vehicle were perfectly level. The installation is a very doable DIY project.



by:

The hardware and design look great. The issue is that it is dependent on a companion app. The app the manual says to download is incompatible with the current Android OS. The other available Weigh Safe app, won't take/use the "optional" weight distribution load ratings so that according to the app my F-150 with max tow package rated for 12000 lbs with 1220lb tongue wt rating when using a WDH. Weigh Safe customer support puts you on hold for 10 minutes and then punts you to voice mail. Hence the single star.



by:

I should have bought this sooner. I had a recurve r6 it is not even comparable to Weigh Safe True tow. I have very little dolphin effect pulling a 11.400 lb bumper pull with a 2022 f350 dually.

Works well. Scale provides needed info. The hitch is very heavy.

Works as designed. Easy set up. Good instructions



by:

Easy enough to setup using the instructions. Only critique would be the trailer brackets twist slightly on the tubing since the bolt pattern isn't identical to the tubing. I recognize its multi-trailer but wish they included some shim stock to make it more visually appealing.



by:

I have received the hitch, delivery was very quick, which has always been the case with E TRAILER. I haven't installed it yet. Etrailer is my go to source for any trailer parts.

Great customer service and timely deliv ery!

the entire process was simple and no is sues.

Hitch has performed perfectly for towing our 40 foot travel trailer.
It is nice to see the tongue weight when setting up for traveling each time adding peace of mind while traveling.



by:

The hitch is perfectly fine. The box was destroyed.



by:

Rate based on early thoughts. Extremely well built with high, smooth tolerances. Instructions are well written. Haven't towed yet. Will next weekend.

Weve towed several times now with no issues. App is easy to use to calculate pre-load settings.



by:

It makes pulling out Brinkley Z Air 315 (38Ft+) so much easier! I really like that backing up causes zero issues. Once I learned how to use the trailer tongue jack to relieve pressure during connecting, it made it so much easier.



by:

The instructions described the setup well. I can open my tailgate with this hitch!!! AWESOME!!!!! It's good to have peace of mind regarding whether the hitch is adequate for the tongue weight. I was surprised to see that I was 100lbs over what the rated tongue is listed as. My last hitch was inadequate...this one is perfect. Haven't towed with it yet, but I feel quite confident that it will safely handle the load.

  • Recommended WeighSafe Weight Distribution Hitch for a 25 Ford F250 Towing a 26 Grand Design Mav
    This is a great choice Joe and thanks for reaching out! Weigh Safe True Tow Weight Distribution Hitch # WS49MR would be a good match for your setup. Since your Grand Design toy hauler will have a loaded tongue weight between 1,300 and 1,600 lbs, this hitch falls right in the recommended weight range. One thing to keep in mind is that toy hauler tongue weight can vary quite a bit depending on how you load the garage area. If you expect the tongue weight to regularly exceed 1,600 lbs...

  • What Info Is Needed to Pick Out Weight Distribution for Travel Trailer
    Hey Brandon, what's the loaded tongue weight of your travel trailer? With just that I can tell you which weight distribution system you would need. Each WD system has a tongue weight range and ideally your trailer's tongue weight falls as close to the middle of the range as you can.

  • What Weight Safe Weight Distribution to Use for 11,300 lbs GVWR Trailer
    Hey Vernon, great to hear from you again! For your trailer that has a GVWR of 11,295 lbs I actually recommend stepping up one level and going with the 18.5K # WS49MR which has the same 6" drop and fits a 2-1/2" hitch receiver like the 12.5K # WS59MR you were looking at. Here's why: Wight distribution systems (WDS) are designed to help with tongue weight (TW) so, contrary to popular belief, you'll actually choose a WDS based off of your TW as opposed to the GVWR. Since a properly loaded...

  • Solution to Allow Weigh Safe True Tow WDH to Clear Tailgate
    Hey Forest! You aren't going to get the clearance you need from moving to the Heavyweight. Even if you did, that system is going to be overrated so you wouldn't want to use it with your trailer. You're better off sticking with the Middleweight # WS94RR (2" shank) or # WS59MR (2-1/2" shank). All of their shanks are the same length and you can't use shanks from other systems so that is out of the question. An extender isn't going to work well either and it will cut your tongue weight capacity...

  • What Weight Distribution Hitch do I Want, My Lightest Trailer is 10,000 Pounds Total Weight?
    Hello Danny, I’m really glad you mentioned the Equalizer! When sway is the issue, that one and the Weigh Safe are definitely my go-to options. They both have 4 point sway control, with straight spring bars and frame brackets. They can be a little noisier than the chain style setups, but that’s because they’re actually creating the friction that reduces sway. You mentioned your lightest trailer is 10K. When it’s loaded, you want your tongue weight to be 10 to 15 percent of your total trailer...

  • Recommended Weight Distribution System w/a 2-1/2" Shank for a 17,500 lbs Trailer
    Hey Arnaud, thanks for the information! The Weigh Safe True Tow Weight Distribution Hitch item # WS49MR would be a great option for a 17,500 lbs trailer. It will work with tongue weights up to 1,850 lbs but it's not going to be overrated for your trailer's lower tongue weight. The built in scale will also allow you to adjust how you load your trailer and account for the weight of anything in your F-250's bed. The Weigh Safe item # WS49MR has built in sway control that will keep your trailer...

  • What Weigh Safe True Tow Weight Distribution Hitch Should I Use For My Momentum 25G
    Hey, Brent. Thanks for sharing the GVWR and hitch weight. Based on that information, yes, the Weigh Safe True Tow Weight Distribution Hitch part #WS49MR will work for your setup. One thing to keep in mind is that the 1,400 lb hitch weight rating does not include the weight of propane tanks, batteries, or any gear loaded in the front of your Momentum 25G toy hauler, which should be factored into your total tongue weight. The Weigh Safe True Tow is pretty awesome. A coworker and I installed...

  • Will the Weigh Safe True Tow Weight Distribution Hitch WS49MR Work w/a 6" Tall Trailer Frame?
    Hey David. The Weigh Safe True Tow Weight Distribution Hitch item # WS49MR you were looking at, does indeed work with trailer frames up to 6" tall. If your trailer's frame ends up being taller than that you'll need to use the Weigh Safe True Tow Weight Distribution Bracket Kit item # WS89RR. This will work on frames up to 8" tall. The Weigh Safe True Tow Weight Distribution Hitch item # WS49MR works with trailers that have up to a 1,850 lbs tongue weight. This system comes with a 2-5/16"...

  • Suspension Enhancement Recommendation for 2025 Chevy Silverado Trail Boss
    Hey Brian, we can help but there isn't a Timbren kit that fits the Trail Boss version of your 2025 Chevy Silverado Trail Boss. Instead we have the Pacbrake Alpha HD Air Bag kit part # PB56SV which was intended to fit the Trail Boss models so it is your best option. Unlike Timbrens with air bags you can tailor exactly how much suspension support you want from them by changing air pressure so you can get as much or as little support as you want at any given moment. Plus the Timbrens are known...
