All-In-One Suspension System

When towing or hauling a heavy load, you may encounter a number of problems that can make your driving experience difficult or dangerous, such as sway, body roll, or bottoming out. When your vehicle is weighted down, your factory leaf springs can't counteract these problems to the extent that they are supposed to. The weight will overpower the leaf springs and cause them to twist or flatten out. When that happens, they cannot support, level, or stabilize your vehicle effectively. Additionally, because your factory leaf springs are passive, they won't begin to tackle problems such as sway until those problems have already started.


Diagram of RAS Installed

Roadmaster Active Suspension (RAS) kits enhance those passive leaf springs by converting them into a mechanically active, all-in-one suspension system. RAS kits have variable-rated coil tension springs that automatically adjust to your heavy load. Other suspension systems only solve a few problems and usually at the expense of other improvements your factory leaf springs may need. RAS, on the other hand, is a unique kit that provides everything you want in a suspension system without any trade-offs. It eliminates bottoming out like air springs, reduces sway and body roll like sway bars, keeps your ride level like helper springs, and improves traction and braking control like traction bars. This improves your vehicle's stability, handling, and control while you are towing or hauling, as well as when your vehicle is unloaded. RAS also makes your overall driving and towing experience safer and more comfortable, which greatly lessens driver fatigue.


How RAS Works

Close-Up of RAS Tension Spring

Each RAS unit has a powerful variable-rated coil tension spring that converts your passive leaf spring into a mechanically-active system. Once your vehicle is loaded, the tension springs immediately activate to absorb and support the weight. This allows your leaf springs to maintain their bowed position and keeps them from flattening out or flipping over, which greatly hinders their ability to bear a heavy load. The tension springs are variable-rated, which means that the heavier your load is, the more assistance they provide to your leaf springs. Because of this design, RAS reacts instantaneously, whereas hydraulics, air springs, and other suspension systems take time to react. And unlike your factory leaf springs, RAS stops sway and sag before they even start to happen. Additionally, when your vehicle is unloaded, the tension springs disengage, allowing your leaf springs to perform as intended without hardening your ride. RAS won't hinder your leaf springs' movement, nor will it cause any friction between any of the brackets.


Eliminates Axle Wrap and Wheel Hop

RAS Eliminates Axle Wrap

When under a heavy load, leaf springs are especially susceptible to axle wrap, which can cause wheel hop. Wheel hop is when the tires lose their grip on the road, causing a jarring, up-and-down movement. Axle wrap occurs when the circular motion of the tires cause the leaf springs to twist or rotate. If the leaf springs twist far enough, wheel hop can occur. RAS stabilizes your leaf springs by absorbing the force of the load they're trying to support. This eliminates axle wrap and wheel hop, as well as prevents your vehicle from bottoming out. Because of this, less strain is put on your vehicle. And by reducing some of this wear and tear, RAS helps extend the life of your leaf springs, shock absorbers, shackles, and even tires.


Reduces Sway and Body Roll

RAS eliminates sway and body roll

When driving along a curve while towing or hauling a heavy load, the back end of your vehicle or trailer can start to shift with that weight. If your factory leaf springs have flattened or twisted under this load, they won't be able to prevent it from shifting. Because of this, your trailer will sway away from your vehicle. This makes driving challenging and dangerous, as it increases the risk of body roll, which is when your vehicle drastically leans to one side. This can often cause you to completely lose control of your vehicle. Body roll is especially prevalent with multi-passenger vans and vehicles towing long campers, trailers, or boats. RAS provides a much safer ride by reinforcing your factory leaf springs and stabilizing your load. This helps prevent sway from occurring and reduces the chance of body roll while cornering, turning, and swerving. RAS also lessens the rocking motion that happens during windy conditions or when a semi passes by on the road.


Levels Your Ride and Improves Traction

RAS Levels Your Ride

When your vehicle is overloaded, the bulk of the weight transfers to the rear axle. Your factory leaf springs then become overwhelmed by this weight, as they are not strong enough to support it. This causes the back end of your vehicle to sag and the front end to rise, which means that the front tires have lost some of the grip they need with the road. In addition to loss of traction, it can also cause poor headlight aim, unintentional swerving, and an extremely bumpy and uncomfortable ride. RAS bolsters your factory leaf springs and enables them to provide support for your load without compromising ride quality or comfort. This keeps your ride level from front to back whether you are hauling a load in the bed or towing a boat, trailer, or camper. RAS also ensures that your tires have the traction they require while braking and accelerating, which improves the overall driving experience.


Customizable Coil Tension Springs

Adjusting Spring With Spacer

RAS is also customizable. During installation, the coil tension springs can be adjusted to 2 different tension settings or anywhere in between for improved road handling and support. To do this, rotate the springs while keeping the threaded rod still. As you turn the spring, use one of the 2 included spacers as a gauge to measure the widening gaps between the coils. In order for the RAS units to work as intended, you must tension the coils to a minimum of 25 percent with the 1mm white spacer and no more than 40 percent with the 2mm spacer. The springs can also be independently adjusted to compensate for off-center loads such as a handicap lift.


Easy, Bolt-On Installation

RAS Once Installed

This custom-fit kit comes fully assembled and is easy to install. Each RAS unit simply bolts onto your factory leaf spring with the included hardware, and drilling, welding, and cutting aren't required. First, position the eye hook bracket so that it wraps around the top of the factory leaf spring eye. Then the axle bracket secures under the leaf spring and around the factory U-bolts on the other side of the leaf spring pack. Once the maintenance-free RAS units are fully installed, you won't need to monitor them as you would with air springs.


Corrosion-Resistant Steel Construction

RAS Construction Close-Up

RAS is extremely durable and corrosion-resistant. The units are constructed of high-grade alloy steel, and they have an epoxy e-coat on the coil springs to provide extreme corrosion resistance. The brackets on the ends of each unit resist the effects of water and other elements, and they have a salt spray rating of more than 800 hours.

Installed in four hours. Missed the kit for 4x4. Had to disassemble and reassemble. My fault. Raised the rear end by 2 inches. Lots of creaking noises with new installation. Truck rides better and seems higher after installation. Tongue pull steel horse trailer sagged rear end 1 inch. Hoping travel trailer with weight distribution bars will not sag the rear end at all. So far well pleased with the results. Interesting system. 628336

product came very fast! all was packaged extremely well and no damage to any of the items I ordered. I have not installed them yet but I am excited to get them on and hopefully see that they take that little extra sag out of my truck while pulling my travel trailer! watched many video's on the installation process and seems to be very simple and straight forward... thanks etrailer 307783

Review from a similar RAS in Vehicle Suspension


I did a lot of research to determine if I should use airbags or the RAS. For my application the RAS was the better choice. No matter who I asked, no one had a negative comment about this product (RAS). I tow a Jayco Travel Trailer (TT - 9000lbs) and while I have towed boats for years I was new to the type of tongue and hauling weight that the TT exerts on my vehicle. Installation was a breeze. I spent more time preparing my tools and finding my 22mm wrench than I did installing the RAS. There are many Youtube videos on how to install the RAS and I do recommend you watch them. My ride (F150 Echoboost) was smoother while pulling the trailer; however, I didn't feel any change to my daily driving (positive or negative). If you're using a WDH, I recommend these over the airbags. The airbags can be counter intuitive since the WDH should fix most of the weight distribution and level. The RAS works well with all WDH's and once installed you don't have to make any changes to it, unlike the airbags. Get the RAS - you'll be happy you did. 399233

Repeat customer. Just installed my second set of Roadmaster Active Suspension springs. Have not towed with them yet; however the ride on my 2014 F150 6.5' bed pickup is noticably smoother. I expect the result when I do tow my travel trailer to be the same as with my previous truck - night and day difference (no more "white knuckle towing)! 319927

2018 F150 4x4 owners pay attention to this review. I received the order today and unfortunately it was the wrong kit for my vehicle. Even though etrailer confirmed that a RAS3611-B is correct for my truck, it is actually for a F150 4x2. I contacted etrailer and costumer service rep was great and verified that initially the same part number came up for my vehicle, causing the confusion. My mistake, etrailer mistake. The correct kit for a 2018 Ford F150 4x4 is RAS3611-Y. etrailer is splitting the cost of return shipping and my correct kit has been ordered. etrailer has great costumer service. 567680

Review from a similar RAS in Vehicle Suspension


I have a 2016 F-150 4x4 with a 2 inch leveling kit and 305 tires. I am towing a 26RR Grey Wolf camper. I beleave it is 4992 lbs dry wait and 7775 lbs loaded. It is meant to be pulled with 1/2 ton trucks. Want to give all specs to be fair to the product. The product was easy to install. I adjusted spring to the black disk. When I hooked up the camper I notice my truck definitely squated less. The towing ride was less bumpy. That is it. It definitely did not improve fuel mileage. I am still at 8.5 miles to the gallon. That is on flat ground, I live in Florida. Still could not go over 65mph without camper feeling loose on the road. 3 stars for now until I tow other trailers. It was an improvement but not as much as I was expecting. Still going to go truck shopping for a bigger truck to solve my towing needs. Side note: truck looks great and rides way better without a trailer in tow. 2/22 inf 744719


Comments
The Roadmaster Active Suspension is designed to improve your trucks stability, handling, and control by keeping the truck level even when youre towing. When you say that your camper feels loose on the road, it sounds like your trailer starts to sway at speeds above 65 mph. The best solution for keeping your trailer tracking straight while rolling down the road is to use a weight distribution system with sway control. A weight distribution system will not necessarily improve your fuel mileage, but it will improve your experience towing your 30ft trailer. I have linked a help article on Weight Distribution systems for more information.

Comments
Hello David, I am sorry this product did not fit your truck. I spoke with our Roadmaster Techs and they told me this kit is not a fit for your truck since your truck suspension is not factory spec. This kit is only confirmed to fit the fit-guided vehicles with factory suspensions.

Thanks I put the springs on today’s. I have one question, I adjusted them to the 20% / one millimeter. Can they be adjusted to the 40% with truck sitting on ground if my trailer still has the bounce in it when hooked, or will I need to lift it off ground to readjust if needed. 590227


Comments
According to the manufacturer, when the suspension system is adjusted, the vehicle must be raised with the axle hanging free. This releases most of the spring tension.

After debating whether to go with these or airbags for a year I’m very happy with my decision to purchase these for my 2015 F150.

I really like the suspension add on. It keeps my truck level when towing our 9000 lb camper bumper pull. I get great stability on the road and it helps with handling the tongue weight on my 2013 Toyota Tundra 1/2 ton. It doesn't change the stiffen the suspension of my truck until I add weight. So, you don't notice it with normal driving. Installation went smoothly. The components were high quality and heavy duty. I recommend it. 577747

Prompt shipping, good price, happy. The Roadmaster was easy to install and works as advertised. Truck used to squat under weight. Now even with the riding mower in the back, I cant even tell its there. No squat and good handling. Unloaded there is no effect on ride. Cranked to max, raised the rear about an inch.

Just like your advertising said they were very easy to install. My ride has not been affected it still is a great ride for a truck. After the installation the rear end of my truck was 2” higher which will help when I hook up my camper, instead of sagging now my truck is level they are a great product . Thank you 540473

Review from a similar RAS in Vehicle Suspension


I have Nissan 2500 van that I have converted for traveling. Its gross weight is 9000 lbs, and with all that is in it everyday it weighs around 7000 lbs. It has enough weight it sags. I occasionally pull a trailer, which makes the sag even worse. I install the RAS, and it added about 1 1/2 inches to the truck height. I haven't pulled with it yet, but around town it rides great. Maybe, a very slight stiffening of the suspension, but nothing like what Timbren does to a truck. These things were terrible to install. The instructions said there wasn't much clearance on this vehicle, so take apart the unit and put the spring hooks on before lifting the vehicle. I thought I was going to have to unbolt the springs. Using a jack in the right place allowed me to finally getting them into place. It did require much frustration, and some choice language before I finally got them installed. I'm still looking forward to towing with them to see if the sag problem is fixed. I do recommend these. Again on a Nissan van they are a b*tch to install. 650068

Review from a similar RAS in Vehicle Suspension


I bought this based on I think the same product I bought several years ago for a 1997 Dodge Ram 1500. At that time, I bought a kit for for a Ram 2500 and was very impressed. I put a truck camper on the Dodge and I don’t think it settled an inch and when I drove it I hardly knew the camper was back there at all. No sway and no handling problems at all. This time I bought the kit for a Nissan Titan, pulling a 25’ travel trailer (about 7000#). The truck rear still settles and is not in a level attitude in transit without the weight distribution hitch. The suspension kit makes it better but not as much as I expected. 565780

I installed the product easily within less than an hour. On the test drive after, my truck rode smoother and more precise than prior to the install.

I have had this product a couple of months now with two trips pulling my travel trailer. It has helped in leveling out the truck/trailer so that less pressure is applied to the weight distribution system. Product is easy to install, I didn’t even need to take the tires off. It also is easy to adjust to fit different hitch weight. It did make my truck ride a little ruff but not to a point that is uncomfortable. I chose this product over air type products as I didn’t want to have to mess with it. I would recommend this product. 593932

Delivery was on time and the product was good and ready to go! Jacked up the truck put it on stands and 1hr 30mins later I was driving off for a test run. Works just like it says it would. No body roll, takes off so much smoother, and I did about 40 over those big rolling neighborhood speed bumps and it was super smooth. Before RAS it would have a real bouncy feel over the speed bump now it attack the bump if you know what I mean. I tow a 25' trailer so I can't wait to see how much bounce is taken out when I'm driving over the dippy roads through the mountain pass here in WA. Thanks E-trailer! 313970

My initial review was was 5 star rating and after one year of use it still remains a 5 ??. I have a chance now to tow my 25’ travel trailer for a season and works great. It helps with proposing and reduced the little sag when I have her loaded up for a long trip. Highly recommend RAS with a WDH combination for smooth comfortable towing experience.

  • Will Weight Distribution be Needed if Using Roadmaster Active Suspension on a 2015 Silverado 1500
    Suspension enhancement products such as Roadmaster Active Suspension # RAS3611-S serve a different purpose than weight distribution. Suspension enhancement is designed more for loads carried in the tow vehicle whereas weight distribution is meant to redistribute tongue weight from a trailer across all axles of the tow vehicle and trailer more evenly. The product to use to combat rear end sag is a weight distribution system. However, often times the suspension on 1/2 ton trucks will still...
