Features to know about

Stop Fighting the Wheel on Long Drives

You've had tough experiences while driving your rig. You white-knuckled when a semi blasts past and nudged things back on course through heavy winds. It's exhausting. With this stabilizer in place, the coach tracks straight instead of wandering and it cuts down on those constant corrections you have to make. It makes a huge difference when you spend hours on the road. When you stop fighting the wheel, you won't be worn out when you finally park.

Stay in Control When a Front Tire Fails

A front tire failure is a nightmare scenario everyone dreads because it happens fast and the wheel yanks hard. If you've been through it, you know how helpless it feels when the rig wants to pull out of the lane. That's probably when this stabilizer really matters the most. It helps hold the wheel steady so you can slow down and bring your coach under control. It won't stop a tire from failing, but it can keep that situation from turning into something worse.

Bolt-On Install with Vehicle-Specific Hardware

safe t plus bolt on installation

This stabilizer bolts on with hand tools and includes the mounting hardware for your vehicle. Once it's mounted, it has to be centered and torqued properly to work. If you're comfortable with those adjustments, you can handle it with some extra time. If not, we can help you find a trusted installer to handle the job. Either way, you only have to do it once, and it stays put.

After trying out both the Safe-T-Plus and the Roadmaster Exact Center, I can say they both do a great job keeping your motorhome going straight down the road. The main difference is how they feel. The Exact Center reacts fast when you come out of a turn, the wheel snaps back to center quick, kind of like a rubber band. It’s tight and responsive, but it can feel a little jumpy if you’re driving a bigger or top-heavy rig. I like that the Safe-T-Plus has a more relaxed feel. It uses one big gas strut that gives you smooth, even resistance the whole time you’re steering. Instead of snapping back, it just helps you stay straight without fighting the wheel. It kind of feels like driving a luxury SUV instead of a motorhome.

I was impressed by how simple the install was after watching two installs. The stabilizer bolts to the sway-bar bracket and clamps around the tie rod with U-bolts. If you’ve got some basic tools and a little time, you can do it right in your driveway.

If you’re trying to decide between the two, here’s the best way to think about it: the Exact Center is great if you want quick response and tight steering, especially on smaller rigs or twisty roads. The Safe-T-Plus, on the other hand, is best if you want smooth control on big rigs or windy highway drives.

Install was pretty straightforward, and can be done in a driveway or garage on the ground. It's not overly complicated as far as getting it in place and the adjustment to get it dialed in perfect is easier (in my opinion) than the roadmaster, and not hard to do. I would give it a 5/10 difficulty with that rating being slightly high just because you will be under the RV and it can get tight.

We have a 31 foot coach with the 2024 Ford E450 chassis. The original equipment was wholly inadequate so we replaced the steering stabilizer with what I thought would alleviate the wild ride we were having when we were passed by a semi truck. It didn’t. Now we had the wild ride, plus it was constantly pulling to the left. I was constantly steering to the right to go straight.

The good folks at etrailer installed the Saf-T-Plus on our coach and it’s a whole new experience. No more fighting the wheel. I feel confident that we will go down the road without any more wild rides!

Also, the experience with etrailer was first rate before, during and after the installation.

See what our Experts say about this Safe-T-Plus Anti-Sway Bars

  • How Does Safe-T-Plus Steering Stabilizer For E350 E450 Compare To Roadmaster Reflex?
    Ben, both aim to keep your steering centered, but the # ST98MR uses a sealed hydraulic piston with a calibrated spring instead of external coils. That gives you smoother centering and better control when the road surface changes. It’s also fully maintenance-free and tuned specifically for the 2007-up E-350/E-450 steering gear. If you already have a Reflex and still feel like the wheel floats, the Safe-T-Plus is the logical upgrade.

  • How To Keep Forest River Sunseeker Class C RV Straight On Road When Flat Towing A Car
    Randy, absolutely. Towing adds tongue weight that can make your front end feel light. The Safe-T-Plus # ST98MR keeps the wheel centered so that weight shift doesn’t translate into wander. It’s a smart upgrade before your next trip - the improvement in control while towing is huge. Once you try it, you won’t want to drive without it. Which spots are your favorite to travel to?

  • Will ST98MR Steering Stabilizer Bar Work For 2015 Coachmen Leprechaun 319 MB On Ford E450?
    Yes, Alex - the # ST98MR is the exact fit for your E-450 cutaway chassis. It mounts using existing hardware, no drilling or welding. You’ll notice the biggest improvement when driving in crosswinds or on grooved pavement. After installation, take it for a short drive and fine-tune the centering point - once set, it’s maintenance-free. Do you usually tow a car behind your Leprechaun? That extra weight makes this upgrade even more noticeable.

  • How Can I Make 2008 E450 Thor Motorhome Less Fatiguing Driving On Long Trips?
    Howard, start with a steering stabilizer - the Safe-T-Plus # ST98MR is built for your chassis. It automatically centers the wheel, so you’re not fighting to keep it straight for hours. Pair it with a proper alignment and good tire pressures, and it’ll feel like a new coach. It’s one of those upgrades you notice the second you hit the highway. What model Thor do you have?

  • Upgrade To Keep Ambulance conversion 2022 E450 Tracking Straight On Road - Wanders When Loaded
    Kara, the best fix is the Safe-T-Plus # ST98MR. When the rig’s loaded, side winds and road grooves grab the steering more - the stabilizer counters that automatically. It’s a safety upgrade a lot of emergency and utility fleets run because it keeps control consistent no matter how the weight shifts. Installation’s straightforward, and you can feel the benefit immediately.

  • How To Stop Wandering On Highway When Semi Passes 2018 Thor Chateau 28Z Class C RV
    Mike, you’ll want to start with the Safe-T-Plus # ST98MR. Sway bars reduce body roll, but they don’t fix steering wander. The # ST98MR keeps the wheel centered automatically, so those truck blasts or gusty days won’t push you around. It’s the most noticeable handling upgrade you can make on an E-450 based on the issue you are describing. Once installed, you can always add heavier sway bars later if you want to tighten the feel even more, but I'd do this first and see how you like it as...

  • How To Fix Steering Play On Highway When Driving Class C RV 2023 Winnebago Minnie Winnie E450
    Sharon, you’re spot-on with the Safe-T-Plus # ST98MR for that E-450. It’s tuned for 2007-up cutaway chassis and bolts right on with the included bracket kit. It’ll take out that loose, “drifty” feeling you get when trucks pass or the road crown changes. Once centered, you’ll steer with fingertip pressure instead of constant correction. Have you upgraded your front shocks yet? A stabilizer like this works best when everything else up front is solid.

  • Is Steering Stabilizer Needed With Aftermarket Shocks On 2021 Jayco Greyhawk?
    Absolutely, Derrick. The # ST98MR works great alongside upgraded shocks - in fact, that’s a perfect pairing. The shocks control bounce, and the Safe-T-Plus handles steering stability. Together they make the Greyhawk feel like a big SUV on the highway instead of a box truck or mobile living quarters. Just install the stabilizer, center it, and you’re done - no adjustments needed later. How far do you normally go on each trip? Other folks reading this, what do you use for keeping steering...

  • 2014 E-350 Cutaway Delivery Van Is Hard To Keep Straight On Highway When It's Windy
    Yes Carlos, you'll want the Safe-T-Plus # ST98MR steering stabilizer, designed exactly for that E-350 (and E-450) chassis. The stabilizer acts like a shock absorber (better than other options on the market) for your steering, holding the wheel steady against gusts and uneven road crowns. Most fleet users say it cuts down on driver fatigue immediately. You can install it in under two hours using hand tools. What do you think? Can you handle this install?

  • How To Keep Steering Straight On 2016 E450 Shuttle Bus That Pulls After Hitting Bumps In Road
    Pastor Jim, that’s a classic case where a steering stabilizer like the Safe-T-Plus # ST98MR makes all the difference. It applies equal hydraulic force to return the wheel to center after bumps, keeping the driver from constantly correcting. It’s a simple bolt-on and doesn’t interfere with normal steering. Once centered, you’ll notice straighter tracking and less driver fatigue on long routes. How long do you normally drive in one shift? Do you go on the highway a lot or mainly in town?
