Thats odd Mike at Lippert keeps telling me I can not install 8k springs on my 7k axles.
I have seen his name on another post, but who is the service manager at Lippert? Thanks Lonnie
The experience with my own 7000# spring replacement is that the new ones will look the same after you change them.
It happened to me that I changed them for nothing, and lippert told me my old ones might be to soft, but the new one on the same place look the same so I keeped the old ones for spares.
The Lippert springs used have a flat section in the center and when loaded they bend back. Most ached springs will not bend in W but if there is a flat section and loaded I feel it can't help but bend backward. If your plates and U-Bolts are loose they will surely make the spring look much more bend in W.
Just my experince that Lippert never clarified with me that the spring all look like that when loaded.
StevenJ,
I would take the parts and trust that Lippert has made the needed changes to their suppliers so the "Spring" problems they have had go away.

I e-mailed Lippert again and responded right away, they said a serviceman e-mailed me in january 2010 for a shipping address to send new parts. I didn't see the e-mail or get a phone call, but it seems they are ready to resolve the problem now. My original e-mail was in January 2010. They are offering to send new springs and anything else I need. They said the new parts are made from another manufacturer and won't be the same parts. My question is should I take the parts or not, one post I read said the new parts were not any better than the old ones. I asked about going to a 8000# leaf springs(we have a 2008 3600RL Bighorn, 7000# axles), Lisa said the they may be too stiff for the frame and it may cause the frame to develope camber( frame bending?). I can do the work myself with 10 ton jacks and the proper tools, I'm just wondering if I should get the 7000# or bump up to the 8000# springs, I should ask Lisa if the warranty would be voided if I used the 8000# springs. This all transpired in the last week so if anyone else is having issues it would be a goood time to e-mail them. Go to the Lippert site, then go to service tab.
Trust Lippert? Now that is a novel idea.
I had been e-mailing to Lippert and dealing with Lisa. Her last e-mail said they are waiting for me to tell what parts I need and they will send them. It looks like I should upsize to 4000# springs, my concern is that Lisa said it may causr the frame to camber(frame bending) from too stiff of a spring. I was wondering if anyone had upsized and had any problems or maybe if you did check for frame bending?
I have been dealing with Mike at Lippert and he never said anything about frame issues with the upgrade to 8k springs. Just that if I did Lippert only replaces like with like and the total cost would come out of my pocket.
I know that there are a few people on here that have upgraded to 8k springs. Do a search for Lippert warranty doen't care about safety. Good luck.
