Stability Control for Heavy Duty Vehicles

Anti-Sway and Steering Solutions

Large vehicles tend to be harder to handle for a variety of reasons. The center of gravity in trucks and RVs is often considerably higher, resulting in decreased stability. Distribution of weight may be unequal - think of a pickup loaded down with cargo in the rear, or a motor home with cabinets and appliances weighing down one side. This can create an unstable ride even during straight-line movement, let alone during cornering. Merely having greater size and mass makes a vehicle less aerodynamic and more susceptible to crosswinds as well. So what can be done to counter these issues?


Roadmaster and Blue Ox both have developed lines of suspension enhancement products that are designed to combat these all-too-common problems. Each item is customized to fit your vehicle and work with its stock suspension. Not only do these products complement your current system, they are also guaranteed not to interfere with it or with most popular aftermarket add-ons. Therefore, these enhancement products will not affect your vehicle warranty.





Do you need suspension enhancement?

Take a look at the following questions. If you answer yes to any of them, then you should consider a suspension enhancement product.





Benefits of Suspension Enhancement

All of these suspension enhancement products are engineered from high-quality materials to ensure long-lasting, superior functioning components. But they also work to keep your vehicle operating at its best for the long haul. No matter which product you choose, you will notice:





Which suspension product is right for me?

Now that you know that your vehicle would benefit from suspension enhancement, it's time to determine which product is best suited for your particular needs. Please note, these products can be used together for maximum benefit on many vehicles.


Anti-Sway Bar

If your primary concern is reducing the side-to-side movement of your vehicle to gain greater control over it, or if you experience excessive body roll when cornering, then Roadmaster's Anti-Sway Bar is your best bet. Benefits of this stabilizing product include:

Roadmaster Anti-Sway Bar


Roadmaster Anti-Sway Bushings

Many large vehicles have anti-sway bars from the factory, but Roadmaster has created a more effective system. Each anti-sway bar is made of cadmium-plated 4140 chromoly steel that is stronger and thicker than the standard 1020 steel bars that tend to come from the factory. On average, these bars are approximately 30 percent better at reducing sway than the competition. Polyurethane bushings and grommets are used at the attachment points to create pivot points that are neither so rigid nor so malleable as to become ineffective. These durable bushings outlast traditional rubber ones and permit less flex between the anti-roll bar and the vehicle frame, creating a stronger, more reliable system.



Axle Stabilizers

Roadmaster Davis TruTrac

A track rod is your best choice for improving the basic handling characteristics of your vehicle. If you find that your steering often feels loose and uncontrolled, and your vehicle seems to wander into other lanes or veer when you hit potholes and ruts, then this product is for you. Track rods help correct excessive axle side play, which will reduce:


The design of these stabilizers is quite simple. Attach the durable steel rod to your vehicle's axle at one end and then to its chassis at the other to create a sturdy link between the two vehicle components. This connection serves to essentially hold your vehicle's axle in place, steadying it in normal driving situations and, more importantly, on uneven terrain.


There are 2 different types of track rods available:




Steering Stabilizers

If you find yourself constantly oversteering and working to keep your vehicle in line and you're certain that if you were to blow out a front tire you would completely lose control of your vehicle, then you need a steering stabilizer. This is not exactly a suspension enhancement product, but it helps correct some of the same problems that the anti-sway and track bars are designed to correct. In addition to simply keeping your steering firm, a stabilizer will:


Roadmaster Steering Stabilizer

Roadmaster's Steering Stabilizer attaches to your vehicle's steering tie rod on one end, and to its frame on the other, creating a tight connection between the two components that keeps steering firm and controlled. The tempered steel spring on the outside of the stabilizer constantly works to maintain its natural state, pulling back into shape when it's stretched and pushing out again when compressed. This action causes your vehicle to return to center no matter how you steer or how the frame is pushed or pulled.



Blue Ox TruCenter

Blue Ox's TruCenter functions in much the same way, but with one additional, unique feature. This stabilizer has an in-cab, push-button control that lets you manually adjust the tension for a perfect ride. Simply press the button, steer into the most comfortable, controlled, centered position, and release. The TruCenter applies just the right amount of pressure for your vehicle to maintain that desired positioning, keeping it in line for the duration.

I have a 2017 Fleetwood Jamboree 31u. I am looking to reduce the away caused by big trucks/wind. Suggestions? thanks 80702

Reply from Chris R.

A rear and front sway bar will do wonders for the sway you're experiencing on the highway. For your Fleetwood Jamboree, which is built on the Ford E-450 chassis, I recommend the Roadmaster # RM-1139-147 for the Rear and # RM-1139-176 for the Front. 66457

What fits my W22 chassis 2004 Gulf Stream Sun Voyager 8386 model with the 8.1 workhorse chassis? Suspension products is what I'm looking for to stabilize the coach when driving anywhere. 78591

Reply from Chris R.

For your Workhorse W22 chassis I highly recommend starting with a rear sway bar for which Roadmaster # RM-1259-109 will work perfectly. This will make significant improvements to the stability of the RV as you travel down the highway. Adding the Steering Stabilizer # RM-RBK13-RSSA will also make a huge difference. 63785

I have a 2020 jayko 31 ft greyhawk built on a 2019 e450 chassis. Hard to keep driving straight when passed by trucks on highway. What can help 77715

Reply from Chris R.

A rear sway bar will drastically improve the side to side movement you're experiencing with passing trucks - the Roadmaster # RM-1139-147 will work great for the Jayco Greyhawk built on the E-450 chassis. Another add-on that will really help is a steering stabilizer so you don't have to work as hard to keep the RV in a straight line. For this I recommend the Roadmaster Reflex # RM-RBK24-RSSC . 63266

I have a 2016 Thor Axis on a E350 chassis What do you have to replace the factory drag link assembly. 76087

Reply from Chris R.

We wouldn't have a direct replacement for the drag link on your E-450 chassis (you may need to go through Ford directly for this) but we do have steering stabilizers that will help a lot with issues you might be having. For your 2016 Thor Axis the Roadmaster # RM-RBK24-RSSC will work perfectly. 62165

We have a 2018 Thor Four Winds 31W on a Ford E450 Chassis. We want to add sway bars, front and back and a steering stabilizer. What do you recommend? 74223

Reply from Chris R.

For your Four Winds on the E-450 chassis you will need the Roadmaster # RM-1139-147 for the Rear Sway Bar and part # RM-1139-176 for the Front. The Roadmaster Steering Stabilizer # RM-RBK24-RSSC will work perfectly. 60390

good afternoon ... I have a motorhome 32 winnerbago suntar 2019 and when I am driving it 50 miles it does not stay stable that you recommend and thank you very much 72705

Reply from Chris R.

This is a fairly common issue but it's easily fixed with a couple stabilizer components. Your Winnebago is built on the F-53 chassis, so adding the Rear Sway Bar # RM-1139-146 and Front Sway Bar # RM-1139-140 should be enough to drastically improve your ride. If after adding these you still feel some room for improvement, the next step would be the Steering Stabilizer # RM-RBK22-RSSA . 59650
