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.

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

  • Which Safe-T-Plus Steering Stabilizer Is Best For 2025 F53 Chassis With V8 Engine?
    Gina, the # ST85MR steering stabilizer was designed specifically for the 2021-up F-53, such as yours with the 7.3L V8. The mounting points and steering gear changed slightly from older years, and this model comes with the correct updated bracket kit. It covers all chassis from 16K to 24K GVWR, so you’re set. What motorhome do you have on that chassis? I can confirm exact fit.

  • 2021 Forest River FR3 33DS Has Steering In Road Even Though Bushings And Alignment Are Good
    Jeff, some play is typical, but that floating feel can be cured with a Safe-T-Plus # ST85MR. It keeps the wheel stable and centered so small inputs from the road don’t translate to big corrections at the wheel. You’ll still steer normally it just stops the constant side-to-side motion. Would you like a quick torque spec rundown for install to see if it’s a job you’d tackle yourself?

  • Steering Stabilizer To Keep 2021 Fleetwood Bounder Motorhome On The Road Straighter
    Don, I would install a steering stabilizer like the Safe-T-Plus # ST85MR. Your Bounder’s on the F-53, so this model is the perfect match. It’ll hold the wheel centered against wind and road crown so you can stop “sawing” the wheel all day. Most drivers describe the difference as night and day. Where do you plan to have it installed - dealer, RV shop, or at home? I can point you to the easiest alignment process afterward.

  • Is Safe-T-Plus Steering Stabilizer Similar To Roadmaster Reflex For Class C RV ?
    Barbara, both aim to center the wheel, but the # ST85MR is heavier-duty and tuned for the bigger Class A F-53 chassis. It uses a sealed hydraulic piston rather than coil springs, so the centering force is smoother and self-adjusting. It’s also maintenance-free and rated exactly for your chassis weight. If you liked what the Reflex did on your Class C, this would feel like the next level up. Have you driven a coach with one before?

  • 2021 Jayco Precept 34G Drifts To The Right When Road Is Uneven. Alignment Is Fine.
    Kelly, that’s where a steering stabilizer like the Safe-T-Plus # ST85MR shines. It provides hydraulic resistance to offset crown and crosswind, so the wheel stays centered instead of slowly pulling. It won’t fight you at parking speeds - just keeps you straight once you’re rolling. Have you noticed if it’s worse when towing or even when running solo? That’ll help gauge how much difference you’ll feel. I know you said alignment is fine, but I'd make sure the tires are wearing evenly as...

  • Keep Having To Correct Steering Wheel On 2023 Coachmen Mirada 31FW On Ford F53 Chassis
    Steve, absolutely. The Safe-T-Plus steering stabilizer shock # ST85MR fits your 2021-up F-53 and eliminates that constant micro-correction. It centers the wheel automatically and makes long drives much calmer. Most Mirada owners say it feels like a totally different coach once installed. Do you plan to tow a car behind it? That’ll make the upgrade feel even more dramatic.

  • How To Keep 2023 Thor Windsport 34J Straight On Windy Day
    Linda, the Safe-T-Plus # ST85MR is the single biggest steering upgrade for that. It automatically holds center through wind gusts and passing trucks so you can actually relax on long stretches. Installation is straightforward with the supplied 2021-up F-53 bracket kit. Do you plan to install it yourself or have a shop handle it? I can share setup tips either way.

  • Steering Feels Twitchy Even After Alignment On 2022 Tiffin Open Road 32SA
    Randy, yes - that’s exactly the fix. The # ST85MR keeps the steering on-center through a hydraulic piston that resists drift. Alignments correct geometry this adds real-time stability so you aren’t chasing the wheel. You’ll feel the coach hold its lane with far less effort. Do you know what your tire pressures are at? That can also amplify the effect once this stabilizer’s installed.

  • How Does Safe-T-Plus ST85Mr Steering Stabilizer Compare To Blue Ox TruCenter F53 Chassis?
    Bryan, both reduce wander, but the # ST85MR is simpler and fully automatic. The TruCenter uses an air cylinder with a manual reset button the Safe-T-Plus uses a sealed hydraulic piston that recenters itself instantly - no switches, no maintenance. Most owners of 2021-up F-53 rigs prefer the Safe-T-Plus for the “set it and forget it” operation. Have you already installed suspension upgrades, or is this your first handling mod?

  • 2022 Winnebago Adventurer 35F On Ford F53 Chassis Is Wandering On Highway When Truck Passes
    Hey Tom! Yes, the # ST85MR is made exactly for your 16–24K F-53. It keeps the wheel centered hydraulically so gusts or passing semis don’t shove you around. You’ll feel the wheel settle and track straight instead of drifting. It’s a bolt-on install that takes about 90 minutes with basic tools. Where do you usually drive most - open highways or mountain grades? That’ll help fine-tune your setup tips.
