When your rig leans hard through corners or quick lane changes, it can feel like the whole front end wants to keep going in a different direction. This 1-1/2" diameter Roadmaster front anti-sway bar ties the axle to the chassis so weight transfers evenly through turns. The result is a level ride that stays composed on curves, off-ramps, and uneven pavement.
Crosswinds and passing semis don’t need to mean fighting the wheel. By bracing the frame against the front axle, the bar keeps side-to-side motion in check so the vehicle tracks straight with less steering correction. It cuts out that “tail wagging” feel and helps hold your line no matter what’s blowing across the road.
Hours behind the wheel can wear you down if you’re constantly correcting sway. With this setup, the steering stays steady and the body stays flat, so you can relax your grip and stay fresh all day. It minimizes effort to stay centered and makes driving smoother and more predictable mile after mile.
Strength is the heart of this system. The bar is built from thick 4140 chromoly steel—harder and tougher than standard 1020 steel—and delivers nearly 30% better resistance to sway. Polyurethane bushings resist oil, gas, and ozone, so they don’t squish out or break down like rubber. That means longer life and consistent support through every turn.

Getting it on is simple. The kit includes heavy-gauge mounting hardware, bushing lubricant, and step-by-step instructions. It bolts directly to the front axle and frame with no drilling required and works alongside most popular suspension add-ons. Once in place, you’re ready for a more planted, confident drive.

Today, we're going to take a look at the Roadmaster front anti-sway bar.Now, this is a custom fit part. It is designed to fit the 2012 to 2016 international TerraStar trucks. And on a custom fit part like this, I do recommend for you to go to our website, use the fit guide, put in your year and model vehicle and it'll show if this'll work for your application.Now, this anti-sway burrow helped minimize side to side movement, helps improve overall stability of your vehicle. It'll help let you execute turns, quick maneuvers with confidence and it'll allow for a nice level ride even on irregular surfaces. Helps reduce driver fatigue because it'll minimize the effort that's required to keep your vehicle in line, and it diminishes the effects of any cross winds, passing motorists and shifting cargo.As I mentioned, it is designed to fit your vehicle, work in conjunction with its suspension system. Basically, it attaches to your front axle and into the chassis, and it uses the weight of the axle to brace your frame as it shifts and turns.
It is engineered to avoid interference with most of your popular aftermarket add-ons and accessories.It does come with the polyurethane bushings instead of your standard rubber variety. Polyurethane's a lot longer lasting system. It's more durable and resistant to damage that can be caused by oil, gas, or ozone. And of course, less wear will mean less give in your system and better support.The bar itself is constructed of a thick 4140 chromoly steel for superior strength. The bar diameter is one and one half inches.
All this laid out here on the table's included. It's all the heavy gauge mounting hardware you need. Nice set of detailed instructions and how it all installs, and even include a little tub of bushing lubricant to use on the bushings when you go to install them onto your system.Now, these parts are made in the USA, but that should do it for the review on the Roadmaster front anti sway bar.

I have taken a few trips with the Clatter Cabin now. It’s been enjoyable to drive. Since then I have replaced the exhaust from the engine back with 2 12 inch pipe. I was able to get the pre bent exhaust parts over the axle and clear your rear sway bar nicely. Now she purrrrs!

Install looks great Steven! I can't wait for you to take it out for a spin so you can see the difference for yourself, it is amazing what a upgraded sway bar does to your ride, no more white knuckles for you, or your wife. What big stops do you have planned on your trip to the West Coast?

What I recommend is touching it up with a rust resistant paint like Rustoleum. We will be in contact with you about the damage. Please keep an eye on your email.

After a year and many miles I would give it a five star for sure. Made a great improvement over the stock anti-sway bar. With the rear and front RoadMaster anti-sway along with the RoadMaster steering stabilizer the E-450 33 foot class C motorhome drives like a dream. I highly recommend these three products. If not all at once then this order, 1st rear anti sway bar then 2nd front and then the steering stabilizer with the spring on it.

High-five on the install, Curtis! Also, thanks for sharing all the pictures and showing all the angles of the sway bar. They are really helpful for anyone looking to tackle this install themselves at home!

Sounds like a much smoother drive, Riley! I looked up your camper to see how tall it is and I can see exactly why its called a Bigfoot. What's been your favorite place you've traveled to so far with the camper?

The two Roadmastercsway bars weve been using continue to impress and perform like they did on day one. Driving back across the country with some days having stiff criswinds continually we rode comfortably and never had handling or steering issues. I remain adamant that these are undoubtedly the best products on the market for this application and welcome any questions. For reference my truck is a 2018 F350 crew cab DRW, 6.7 diesel 4x4 long bed with Bigfoot 3000 series truck camper. Get the Roadmasters!

This is a complete game changer when using a truck camper Mine is an Arctic Fox 990. I would list this under a must have accessory when using a truck camper. Unloaded ride when you hit off camber bumps is slightly rougher, but hey its a Ram 3500 dually for hauling heavy stuff. Also the performance when carving twisty canyons with an empty truck is astonishing....Watch out Corvetts, here I come!
