Warning suspension problems - Hellwig Springs adjusted incorrectly from the factory

Jayco incorrectly installed the Hellwig helper springs on many Greyhawk motorhomes with the "J-Ride" package. The Redhawk brand may also be affected. If you own a Greyhawk or Redhawk motorhome I strongly suggest you inspect your Hellwig springs adjustment. I have attached photos of an incorrectly adjusted spring and a correctly adjusted spring. If the springs are not correctly adjusted the spring shackle can fail due to the bolts stripping the threads. This can cause loss of vehicle control and or death. Given the weight of the unit the Hellwig helper springs should be adjusted so there is approximately 3/4" - 1" of distance to the factory springs.

Mike, I know it's a problem, but the way you worded it is misleading.

The correction would be that they were installed wrong on JAYCO MH's(not by JAYCO) that work is done by Mor-Ryde as a part of the chassis stretch.

Thanks Grumpy! However ultimately this is Jayco's problem from a warranty perspective. End customers don't deal with Mor-Ryde. Jayco isn't doing a formal recall however if you complain they will resolve the issue.

Just to make sure, it's the left one that is correct, right?

That looks correct, that the one on the left has the smallest distance between the two springs...

The one where the springs are closer together. The picture showing the springs with several inches of clearance between the springs is incorrect. What happens if the springs are installed incorrectly the spring shackles can slap during suspension cycling.

Drat, I just checked mine, and they are installed incorrectly!

Just how dangerous is this? Can it be driven at all, or does it have to be towed to a repair facility?

So I went out and measured ours today and they would. To be be tween 3 1/2 and 4 inches spread on the shackle.

Just wondering. Where did you get this info? I checked the Hellwig site and they were vague or had no info at all.

I got it directly from the Hellwig chief Engineer. My Greyhawk shackle bolts were stripped by the excessive slop in the system. As the motorhome is loaded the factory suspension sags which is normal, the issue is if the helper springs are not tight enough the shackles can be completely unloaded during suspension cycling causing unpredictable failure or at least poor handling characteristics. The handling on my rig improved dramatically after the springs were adjusted correctly.
