Hi. I have a 2025 e450 with a jayco Red hawk motorhome. I would highly recommend the sway bars to the point that I don't think they should be sold without them. I'm not sure about how much affect the steering stabilizer has since I had that put on at the same time as the sway bars. But the sway bars is money well spent You will notice the difference immediately. In fact the person that installed them for me said he noticed a difference just driving it on their parking lot. I hope this helps.

Hi G.

I bought both stablizer bars by Helwig front & back for my E450 super duty RV. (30 foot motorhome). Along with the steering stabilizer and it drives great. The steering is tight and the rv no longer drives all over the road. Before it was like driving a boat. It now drives great now. 200% improvement. You will be happy you did it.

I recently modified my suspension on my 2023 Entegra Odyssey 30Z Class C motorhome with the Hellwig front and rear heavy duty sway bars, Koni Shocks, front and rear Sumo Springs, and the Safe T Plus steering stabilizer. I’m very happy I did all this as I’ve notice an improvement. The drivability and ride comfort is amazing. I recommend all of the above
