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.

A lot of folks choose Class C motorhomes on the Ford E-350 or E-450 chassis because they’re easier to drive than a big bus-style coach. The Safe-T-Plus stabilizer (ST98MR) makes that driving experience even easier. I like that it keeps the wheel centered so you’re not working against crosswinds or passing trucks, and it cuts down on the wandering these rigs are known for. I’m impressed by how much more stable the coach feels, whether you’re a family heading out for a weekend trip or retirees running longer miles. These motorhomes are for families that want to feel safe on the road, and if you want that extra peace of mind, this is an option that really helps. Installation is straightforward with the included mounting hardware, and the lifetime warranty means it’s built to last.

Gas Class A motorhomes on the Ford F-53 chassis are known for loose steering and constant corrections. Owners often say these rigs wander on the highway, and it gets tiring keeping the wheel straight — especially in crosswinds or when semis blow by. The Safe-T-Plus stabilizer (ST28MR) takes a lot of that out by keeping the wheel centered and giving the coach a more settled feel. I like that it reduces the fight in the wheel and makes long trips more relaxed. I’m impressed by how owners describe the change. one Thor Forums user with a Hurricane said, “The install was straightforward and not too hard. Went on a 600 mile round trip and I find the money was well spent. On poor to good roads, the coach tracks well and is a lot easier to drive.” That’s the kind of feedback that shows how much difference this stabilizer makes.



by:

Driving a Class A motorhome built on Freightliner or Spartan chassis can wear you out fast. These rigs are heavy and tall, and the stock steering doesn’t do much to keep you steady on-center. The Safe-T-Plus stabilizer (ST95MR) helps by keeping the wheel straight through crosswinds, passing trucks, and rough pavement, so you’re not always correcting. I like that it makes the wheel feel more planted and cuts down on driver fatigue during long highway miles. I’m impressed by how owners describe the change. one Forest River forum user said after installing Safe-T-Plus and shocks on their Freightliner coach, the freeway handling was “amazing now.” Others mention driving over potholes and ruts after installation and finding that “potholes were no match for the new steering.” That’s the kind of feedback that tells me this stabilizer makes a real-world difference. The sealed design keeps out dust and gravel, and the lifetime warranty gives peace of mind for big-mile drivers. Installation is simple with the included mounting hardware. For local runs it may feel like more than you need, but for Freightliner and Spartan Class A owners who put on serious highway miles, this is a big upgrade over stock steering.

If you’re living the van life or running a Class B motorhome, you know highway driving can wear you down fast. The tall sides of these vans catch a lot of crosswind, and when a semi blows past, you’re often stuck correcting the wheel just to stay straight. The Safe-T-Plus stabilizer (ST86MR) helps by keeping the steering centered so the van tracks straighter and steadier on long runs. I like that it cuts down on driver fatigue you’re not fighting the wheel mile after mile and it makes the ride feel more controlled when the road surface is uneven for those off road campsites.I like how van lifers on the forums say it takes the “wiggle” out of the steering and calms the back-and-forth, especially on longer drives. For short city drives you might not see much difference, but for van lifers who spend hours on the highway, this is a real upgrade that makes the journey a lot more enjoyable.



by:

A lot of Class A motorhome owners with independent front suspension notice the steering can feel light, especially when the wheels drift toward the shoulder or when a big truck goes by. The Safe-T-Plus stabilizer (ST59YR) helps keep the coach centered so you don’t feel that pull. I like that customers with Spartan-based coaches have said they always felt a pull to the shoulder before, and after installing this stabilizer they felt little to no pull at all. I’m impressed by how much confidence that gives drivers who are new to big rigs or just tired of the constant corrections. The sealed design keeps out dust and debris, and the lifetime warranty shows it’s built for long-haul travel. Installation is bolt-on with the included mounting kit, so there’s no welding or drilling. For short local trips you may not notice as much, but for IFS motorhome owners running long interstate miles, this is the kind of upgrade that makes the coach feel safer and easier to handle.

Ford F-350 diesel trucks are tough workhorses, but a lot of owners say the steering feels loose, especially on the highway or when towing. These trucks can wander, and you end up making constant little corrections just to stay straight. The Safe-T-Plus stabilizer helps by keeping the wheel centered so the truck tracks steadier and feels more controlled. I like that it cuts down on driver fatigue you don’t have to fight the wheel as much, even with a heavy trailer behind you. I’m impressed by how solid the build is; it’s a heavy-duty sealed unit designed to handle work trucks and daily miles, and it comes with a lifetime warranty for peace of mind. Installation is straightforward with the included hardware just bolt it on with standard tools. If your F-350 only sees light city driving, you might not notice a huge difference, but for towing, hauling, or long highway runs, this stabilizer makes the truck easier and safer to handle.
