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.

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

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

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

After going back and forth with your install techs before purchasing they said what product to buy. I order it and doesn't fit my truck due to flipped rear axle I gave them pics so product was returned 411832


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.

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

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.

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.

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.

High quality components. We installed the Roadmasters on my 2000 Ford Excursion yesterday. The instructions for installation were clear and concise. The installation took about 45 min. A god bit of that time spent on jacking, wheel removal and replacement. Not a particularly difficult installation. My impressions after test drive: I think the ride was slightly harsher than before installation, but nothing significant. The sway control was greatly improved. Surprisingly, the vehicle seems to handle bumps better, and unexpectedly, braking seems better. All in all, a good upgrade at a reasonable price. Jim 563475

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 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

only drove twice so far. already feel great control of the rear end. much increase of positive traction, with very little drop. extremely easy installation! perfect step by step(with pics) instructions included. also easy to follow video, somewhere. I cant remember where I watched. not hooking up trailer till next weekend, after alignment. maybe I'll be back. overall the "active" concept in this product is exactly what an intermittent hauler wants. there is no feel of preload on leafs when not loaded. the product creates much better roll stability. 2013 silverado 2500hd 691029

Review from a similar RAS in Vehicle Suspension


etrailer has amazing customer service and after talking through a few options for my 2015 Silverado Crewcab shortbed, we decided this product would be the best fit for what I wanted. The RAS comes put together and installs very quickly. It took me longer to get my tools rounded up and the wheels off than to install the RAS. I did set mine to 40% using the thicker gauge for the coils and it appears that added a little height to the back of the truck. No biggie as I planned on leveling blocks later anyway. The ride is definitely firmer and everything the product states about mitigating body roll, bumps and adding traction has held true so far. While I think the product is a little spendy compared to other options, it does more and is well worth the cost. I haven't had a chance to load the bed down yet, but the experience has been very positive unloaded. Thanks etrailer for excellent customer service and great pricing. 542212

2016 Ford F-150 XLT 4x2 - We would get a gallop when we would be towing our travel trailer and after reading several reviews for the Roadmaster Active Suspension System we decided to purchase the system. Just like most of the reviews it took more time to jack up the truck and remove the wheels then it was to install the system. It did raise the bed of the truck about an inch. Anyone who owns a late model F-150 will tell you that it rides just like a sedan. It was no different after the installation. I did take a short drive with the trailer attached and it was a smooth ride (no gallop). At this point I would consider this a success. The one thing that I would like to point out is if you have the same F-150 model that I have I would purchase RAS3611-B not RAS3611-Y. The “B” model has a block that covers the emergency brake bracket on the passenger side install. 754937

There are few lift kits that would prevent this system from being able to be used. However, part # RAS3611-HD is not a confirmed fit for your 2005 Ford Excursion 4x4. Instead, you will want to use part # RAS3621 which is a confirmed fit and would work well for you.

  • Rear Suspension Helper Springs for a 2018 GMC Sierra 2500 Towing a 5th Wheel Trailer
    Hello, I will be happy to help you select some helper springs to improve the ride and level out the truck when you are towing. Timbren springs are an easy install but they will make the ride stiffer when you are not towing. The similar SumoSprings Solo # SSR-207-47 will also level out the truck but will not be as stiff when not towing compared to the Timbren springs. Another option to consider is Roadmaster Active Suspension # RAS3611-HD. Installation is easy with this kit as...

  • Will the Roadmaster Active Suspension Kit Part # RAS3611 Increase Payload Capacity
    No, the Roadmaster Active Suspension Kit part # RAS3611 will not increase either the payload or towing capacity of your 2015 Chevrolet Silverado 2500 as with all of our suspension enhancements. They will work to help take some of the stress off your existing components by stiffening the leaf springs. This will in turn help to improve handling, stability, and vehicle sag. The above kit has a weight capacity of 2,000 lbs which in the case of your 5th wheel trailer would be pin weight....

  • Determining if 2016 GMC Sierra 2500HD Has Overload Springs to Pick Out RAS Suspension
    You'd want to look at the springs of your 2016 GMC Sierra 2500HD to determine if it has overload springs (most likely it does). If the spring pack has what looks like a smaller spring attached to the bottom of the spring pack that is flatter than the rest of the leaves then you have the overload springs and the correct Roadmaster Active System is the part # RAS3611-CHD but if they aren't there you'd need the # RAS3611-HD instead.

  • Suspension Enhancement Helper Springs for 2004 Chevy Silverado 2500 With Suspension Lift
    You can use helper springs on your 2004 Chevy Silverado 2500 with a suspension lift which will absolutely help with the sag and give you an overall better ride. I don't know of a way to tell if you have add-a-leaf or replacement springs, I do know the kit you can use, which is the Roadmaster Active Suspension. The correct one will depend on if your '04 Silverado has the factory top overload springs or not: - Without Top Overload Springs: Roadmaster Active Suspension Custom Leaf Spring...

  • Roadmaster Active Suspension Kit for 2002 Ford F-250/350
    The correct Roadmaster Active Suspension Custom Leaf Spring Enhancement Kit for your 2002 Ford F-250/350 is the part # RAS3611 for the Standard Duty or # RAS3611-HD for Heavy Duty, which offers an extra 1,000 pounds of capacity. I don't believe there is a part number stamped onto these units so what you can do is compare the used set you're looking at with the images we have of these on the product pages or even send me a picture directly and I can try to verify. If you want to be safe...

  • Recommended Roadmaster Active Suspension for 2017 Chevy 2500HD Diesel Towing 13,000 Pound Trailer
    The 2,000 pound standard RAS for your 2017 Silverado 2500, part # RAS3611, is going to be enough to help you tow your 13,000 pound Keystone. If you're only towing the trailer a few times a year this is the route I would go. If you're towing a lot more often then that the HD system, part # RAS3611-HD, is the way to go.

  • Can Gooseneck Hitch Be Installed on a 1995 F-350 7.3 Dually with Air Lift Air Bags Installed
    No, the Air Lift frame brackets are in the location on the truck frame that the gooseneck hitch frame brackets need. This is going to be the case for any of the gooseneck trailer hitches for your 1995 Ford F-350. You could replace the air bags with a different helper spring system. If the truck does NOT have top overload springs you can use Roadmaster Active Suspension # RAS3611-HD. For a similar option you could use SuperSprings # SSA22 which will work with or without top overload springs. You...

  • Suspension Enhancement Kit Recommendation for 2016 GMC Sierra 3500 Towing Fifth Wheel Trailer
    The Roadmaster Active Suspension Kit part # RAS3611 would be a great suspension enhancement setup for your 2016 GMC Sierra 3500. You would not need air bags on top of these. Since these will give you the additional support you need the air bags would be redundant.

  • Rear Suspension Enhancement for 1997 Ford F-350 Powerstroke Towing 50-ft Gooseneck Trailer
    It can be tough to tow a goose neck (or 5th wheel) trailer with a lifted truck because you can lose clearance between the bed rails and the trailer nose. Your included photo (thank you) suggests that you have perhaps 3-inches of clearance between the tops of the bed rails and the bottom of the trailer's nose, which is a little less than what we recommend. The linked diagram shows the usual recommended minimum clearance for trailers. But if you have had no clearance issues and simply...

  • How to Tell if 2015 Ford F-250 Has Overload Springs for Selecting Roadmaster Active Suspension Kit
    Look at the rear leaf springs of your 2015 Ford F-250. You should see a bundle of metal springs held together with a metal band. If you see a spring on top of this that looks separate and angles up to make contact with a bracket on the frame that means you have the overload spring and would want part # RAS3611-SLHD. If not then you would need the part # RAS3611-HD instead.

  • Could Roadmaster Active Suspension Kit be Used on 2000 Ford F-150 with Add a Leaf to Rear Springs
    The Roadmaster Active Suspension # RAS4612 hasn't been tested on your 2000 Ford F-150 with added leafs to the rear suspension. There's a chance it might work, but there's also a large chance you'd have to remove the added leafs to be able to install this. This would give more support than the added leafs anyway so either way this will be a good solution for you. Otherwise you can keep the suspension the way it is and use a Timbren kit part # TFR1525HD which is a confirmed fit and will...

  • Should Timbren Kit Install with Roadmaster Active Suspension Kit on 2017 Chevy Silverado 2500
    Normally if you are going to be near the towing capacity of your 2017 Chevrolet Silverado 2500 a set of Timbrens will be highly recommended for such a long trip. But since you already have the Roadmaster Active System # RAS3611-HD you really would be fine. This kit is adjustable and can give you up to 3,000 lbs of suspension support. If you were in a situation where you needed more support than that you'd be overloading your truck. So long story short...you are good as-is and the RAS...

    To give your 2006 Ford F-250 additional suspension support when towing your horse trailers I recommend the Roadmaster Active Suspension kit part # RAS3611-HD which will give you adjustable suspension support of up to 3,000 additional lbs and unlike other options does not make the ride quality harsh or uncomfortable which is why I recommend it as the best option. You should note that kits like this do not increase the towing capacity of the vehicle overall but instead just help support...

  • Best Suspension Enhancement for 2007 Ford Super Duty for Ride Quality
    The SumoSprings kit part # SSA22 isn't quite as harsh as other suspension enhancement options that fit your 2007 Ford Super Duty but if you were wanting the ultimate in ride quality and suspension support the RAS kit part # RAS3611-HD would be what you'd want instead. Many report improvements in ride quality, stability, handling and support with the RAS kits which is why I recommend them so highly.
