Rancho RS9000XL Rear Shocks - Both Failed...
#11
I'm keeping my fingers crossed that the replacements hold up better.

I inspected my fronts (QuickLIFTS) and they appear to be holding up OK. Living in the salty state of MN I expect and accept some rust but having a total failure after a year is dissapointing. Again, hoping the replacements hold up better. As others have said, performance wise I've been happy.

Wanted to provide one last quick update to close the loop on this thread. Tenneco warrantied my other rear shock and I installed it tonight. It wasn't leaking oil (the adjustment **** was stripped) but was still more corroded then I'd expect after only one year.
Tenneco/Rancho has been great and have stood by their lifetime warranty with pretty much no questions asked and is even paying for return shipping. I can't complain one bit about that.
I'm hopeful I won't be running into this issue again in a year from now. If I do, I most likely will look hard at the Icons.
Condition of the 2nd shock was better than the first as it wasn't leaking oil but still had a lot of corrosion.

I had a leaking Ranchi shock within the first two weeks. They replaced it easily. Eventually switched to a lift kit, but the shocks still ended up with a fair amount of corrosion on them.

There is a trick of putting water proof grease or silicone grease under the switch valve to help keep corrosion at bay and prevent it from seizing up.

I would also suggest Fluid Filming the shock bodies if you are wanting to get longer aesthetics from them.

I did this mod when I had my Wrangler and it worked great. Also, it is my understanding that Rancho will send you just the switch plate assembly if you should have one break rather than warranty a whole shock assembly for it.
