Anyone Have Sulastic Shackles On Their E350/E450 Motor Home?

Thanks Brian for your experience.

I surely hope to hear from someone who has installed them on their heavy E350 or E450 motor home.

The product makes sense. It should be effective at least by some amount. I do wonder how much for a typical heavy motor home.

I've had them on my van for about 120,000 miles. They're great. Just beware, they won't make the ride plush, only remove some of the harshness. FWIWy rear axle weight ranges from 5500-11,000 pounds.
