[@sanny651mn]

Been researching RAS vs Airbags for a few weeks now. There have been a lot of good videos out there, but all of them have been subjective. By that, I mean the only data points were "I think it made a difference" or "I don't feel as much sway or sag". While those observations may have been spot on accurate, they could also be people wanting to believe something so much that they "fake it till they make it". I don't have a reason to doubt them, mind you, but it's human psychology that throws a wrench into subjective observations. Your video, however, is quite different. While you note your personal observations (which again isn't a bad thing), you back that up with science and data. So you partner the "I didn't feel as significant of bumps or nearly as long" with the data that clearly proves that what you felt was indeed correct. This was a killer video man.

I added this to my 2017 Tundra. I tow a 38', 8000lb travel trailer. It made a huge difference. Drove 2000 miles over the past 3 months. The daily driving went from from exhausting to enjoyable. No more bouncing and weaving. A few times I even forgot the trailer was behind me. I can't believe the difference it made by removing the fatigue of having to focus so hard my hands would sometimes get numb from gripping the wheel so tight. Before I would have to stop and take a nap every 2-3 hours. Now, I can drive for 6-8 hours and feel relaxed when I arrive. I can't recommend this enough if your trailer is wearing you out.

[@GoTogetherGoFar]

That's fantastic!

[@jimmieg6218]

Thinking of adding to my 18’ tundra will be towing 30ft trailer 6k ibs. hopefully this help my case.

[@delacruzjeff]

@dustin, did you use the white or the black shim when you installed your RMAS?

[@toolman.dustin]

​@@delacruzjeff I went in between. Wider than the thinnest but not enough for the thickest. My trailer tongue weighs 1050 lbs. I didn't want the ride to be too firm without the trailer. After adjusting RMAS, without the trailer, the back of truck was raised about 1.5 inches and is noticeably higher than before. However, after I connect the trailer the truck only compresses about 1" where it would come down about 2.5" before RMAS. This is measured at the center of the rear wheels to the top of the fender. Without the trailer I lower the tire pressure to 45 psi, but when towing, I raise it to 60 psi. This makes for a comfortable ride. Don't feel you have to pick the white or the black spacer. You could crawl under and adjust the RMAS when towing but I didn't want to have to do that.

[@delacruzjeff]

@@toolman.dustin thanks for this tip. 👍

Just installed on my 2020 F150. I used the 2mm setting and it did raise my rear by almost 2”. Based on this I did just add a 2” leveling kit on the front. Can’t wait to pull my trailer with the improvements and see how it does. Didn’t notice any difference in an unloaded ride.

1- Easy install. Instructions were very clear. 2- KZbin install video by Go Together Go Far was very helpful. 3- Ride improvement was instantly noticeable. 4- Tech support was very helpful. Recommendation: On the instruction for the Bumpstop, bolt selection criteria, such as number of minimum visible threads, would have made the call not necessary. But, it was good to have my selection validated by a human voice from your shop. 5- KZbin performance video by Go Together Go Far is validated. By the way, I do not know or hav ever been associated with Go Together Go Far. My stumbling across his videos were pure luck.

[@Grockin2004]

Just Installed the Roadmaster system on my 2020 F-150. Very easy install. Big improvement in towing my 7,500lb, 25' travel trailer with SwayPro1000! Everything feels much more stable. Sway control is very improved. At least as much as can be using the SwayPro. I've ordered the Weight Safe system. Unloaded ride quality is slightly stiffer than stock, but not much. I think it feels better. I set it to 40% improvement. It did lift the rear about an inch. I have a leveling kit installed so the rake is not bad. Headlights are now somewhat level when towing. Don't wait, install these!

I have it on my AT$ HD and it was a noticeable difference in both empty and loaded rides. this also improved the cornering aspect. The truck was new.

[@JD-so1vl]

Thanks for the video. I'm looking into these and found this more helpful than most others. With that being said, I'm an engineer that actually works on equipment that gets tested on a shock and vibration table (controlled environment) all the time. The data doesn't seem right to me. Let me tell you what I see and please tell me if I have made a bad assumption. Accelerometers measure the change of speed, not the speed itself. This means when your truck was not moving, all the lines should be at zero or at least all the same. I noticed the red line went up and done when you braked so I'm assuming that is the front-to-back axis. The blue I'm assuming is the up and down axis because you could see change when you went over the speed bumps. That leaves green to be your side to side. This leaves me scratching my head because the green shouldn't move unless you turn a corner and shouldn't swap places with the blue just because you added the Active Suspension.

[@GoTogetherGoFar]

Hi JD. Thank you for the feedback! I'm not sure if it helps, here is the exact device I used: www.amazon.com/gp/product/B01MRPKDV9/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I agree with you that I don't think this device specifically measured acceleration/deceleration in terms of speed. I also agree that this was less than officially scientific. That said, I think this device was still a decent measure of the general intensity of the impact of the RAS. It was a relatively independent visualization of what I felt when driving the truck with the RAS installed. XYZ fluctuations were reasonably recorded. I work in a technical field and know enough to not be absolute in my process. Is there a better way to measure and show the impact that may work better?

[@JD-so1vl]

@@GoTogetherGoFar The comment section might not be the place for all my thoughts as I might lead someone astray (I'm still trying to figure this out myself) but as long as I start that... people have been forwarded, right? :-) From what I can tell, the RAS basically make the suspension stiffer. As you hit a bump, the leaf spring flattens out and pulls the "toe" of the RAS down relative to the "heal". Depending on the "K" value of the spring, the force increases the more the suspension flexes which I think is where they get the "active" in the name. So, although I can see it helping reduce porpoise-ing and squat, I don't understand how it can help with the smoothness of the ride, especially when the truck is unloaded. I could be wrong - I'm just trying to understand if they would work better for me than airbags. They might have less maintenance but I think adjustment is key to a good towing experience and airbags are better at that... I think. :-)

[@FatEv1LMoNKeY]

Did it help with load squat?

[@GoTogetherGoFar]

Yes it did.

[@kinetocore]

The RAS manufacturer claims that they also help reduce body roll when cornering or when a gust hits the trailer. Wish you had tested a short slalom section before and after RAS installed. All your force measurements were in the vertical axis which isn’t the only worry with towing a TT.

[@GoTogetherGoFar]

I hear you, and don't disagree. I thought about trying to do that, but I could never think of a way to do it safely.

[@donlanteigne8629]

I just installed mine and tested it on a corner that that has bumpy train tracks going over it, normally you'd have to slow down so that your trucks rear doesn't bounce around the corner, but that's no fun, now I can maintain my speed and go over without the bounce.

[@compbackupcomStCharles]

I was on the fence for an active suspension kit versus airbags to raise and lower my ride house when towing my trailer. That being said you can adjust the active suspension with wrenches which is a pain in the ass to retain that level ride depending on your tongue weight but on the other side of the coin air bag is more convenient but I question if it’s as effective? In a perfect world I would like to install both on my truck 2016 Ford F150 eco-boost. Any thoughts?

[@delacruzjeff]

Just order my RMAS today and wondering if I should set it up with the white spacer or the black spacer? I will be towing it with my 7000lbs 26’ trailer on the 2020 F150 with Equalizer E4 wdh setup.

@@GoTogetherGoFar But does this help with the wind load. I feel like my F150 gets pushed around in the wind. I have a husky weight and sway control hitch. (with this hitch my truck squats very little, 1.5 inches ) My F150 has sway control built in as well. My trailer is 29ft and fully loaded weights about 7,500 lbs. I have plenty of spare trailer towing capability and plenty of payload 1,800 lbs capacity (I have about 1,000 lbs on the tongue), but the wind load is still a concern and I would like to mitigate it without going to a F250, which some people advocate. Do you think the Roadmaster Active Suspension will help or do you know something else that would work better?

[@GoTogetherGoFar]

It sounds like we have similar set ups. My numbers are slightly lower, but very similar to yours. I don't think the RAS is the right solution for wind gust for those of us in this situation. The RAS may help, but that isn't what it is specifically suppose to help with. If it answers your question any better, I am looking to move to an F250 after this camping season. It isn't a tow/hitch capacity issue. I have just become increasingly uncomfortable with the amount of "tail wagging the dog" that occurs in windy or at high speeds.

You can adjust the spring for different tension for loaded and unloaded.

I bet you'd see a noticeable improvement in handling. I haven't been off road like that with mine, but with the way the RAS improves the suspension and handling, it only seems logical.

[@gijoecam]

Despite the claims, all the RAS does is stiffen one half of the leaf spring arch. The net result is a stiffer rear suspension and, therefore, any benefits that may be had from that. To be clear, there's nothing active about it. It's no different than adding spring rate via air bags, stiffer springs, or any other method. The only difference is that at normal ride height, they don't add as much spring rate as some other systems, but ultimately, they're just fancy springs.
