Helwig spring helpers

2018 Jayco Greyhawk 29 w Jay Ride plus. Helwig spring helpers are about 4 inches above stock leaf springs. Would like to get Max benefit from the helpers and plan to tighten them. Anyone have recommendation on how tight I can go.
Thanks
BD

I just spoke to Hellwig Tech support last week with the same question. In my case, my front clearance is about 3 inches and the back was 4 plus. The gentleman I spoke with (thinking it was Tom maybe) said that he would recommend adjusting to 3" all around or more or less if there was any leaning (apparently you can use them to level your ride). He said the minimum is 2".

Online, some of their packages can go to 1/2", but he was pretty adamant that this was not for this product. 2" was as far as he could recommend. I adjusted mine to 3" but have not had a chance to drive it yet. I was not happy with the ride before, but if I can gain a little tail in height, it will bring my tow bar closer to level than it is now.

I could not get a deep well socket on the U-bolts when cranked down to 3", so getting 65 lbft on the locking bolt was totally by guess and by golly. Will check it on occassion. A bit of CLP squirted on them made the process easier as they had slight surface corrosion which mad the nuts a bit stiff using an end wrench.

Thanks, my problem was the tip of the the helper was hitting my grey water line from the bathroom sink and busted it. I have pulled the spring down to about 2 3/4 inches from the OEM springs but was not sure if this was advisable or not. It was installed with 4 inches or more distance between the springs. It clearly solved my contact issue and I had planned to call Hellwig Monday. Lubricant definitely made the job easier. It will be interesting to see if the ride changes. Thanks for the quick response and great information.

Just did mine after talking with Hellwig tech service. I have a 2017 GreyHawk 29w and he told me to set them at 2”. That is what I did. They were set from the factory at 4” and I could see wear where the shackles had chaffed the springs from being loose. The only thing I had to do, and this is probably why the factory didn’t do this, was to cut one of the U bolts away from contacting the exhaust pipe. Otherwise all went well.

Thanks, as you can see I have the same rig. Have been full time for about 18 mos and really enjoyed it.
While it's on my mind I think I will go ahead and tighten to 2 inches also. If I could get a little more ground clearance that would be great
Leveling jacks are just a little too low when retracted.

Just wondering, when you guys are talking about these measurements, where exactly do you take them? I see my helper springs and the adjusting bolts, but where do you measure from?

Measure from the bottom of the dip in the end of the helper spring (where the shackle is) to the top of the main spring below. Hope this helps.

If you set the spring at 3 inches it gives you 2,750 pounds of more support and at 2 inches it gives 3,500 pounds of support. The front of the spring doesn't matter. You can see the front is just a couple inches from the spring support. it's really there as a counterbalance so to speak.

I just did what the manufacturer told me to do. The measurement he gave me was stated for both ends of the helper spring, not just one. After all, they do the research, testing and build the product to perform the way it is supposed to. I asked and they told me what to do.

Sure you can do both if you want, but all the support is at the back. Notice that the center of the Hellwig springpak is not at the center of the Jayco springpak. Another example is Hellwig make a Springpak has NO springs at all in the front of the big front U bolt on the left. It's just like they cut it right off in front of the left u bolt. It looks really weird, but the two big U bolts is what anchors it.
