Yes , the 550 is the 4.5 WJ coil

BTW, I measured the lift - it's 22.5" from the center of the hub to the bottom of the fender, which I believe makes it 4.5"

Hi

Not to belabor the point, but I am at a loss to explain how I wound up with this:



Is this part number (ROR 550) for a 4 1/2" lift spring? Was this what was supposed to come with the kit listed below? I can't find it on your site.



So I show him a picture of his 4.5" coil with a 2" spacer on top of it and he isn't even curious. Just that it is a 4.5" coil. Is it even possible to put a 2" spacer on top of a 4.5" coil and not wind up with a 6.5" lift?

From your picture, I do not see an upper coil spring isolator. That will reduce net lift height by a tad. I cannot tell 100% if you have the lower isolator, but I think I see it there.

Post a full pic from the side to see your ride height. Perhaps the coil was cut. Don't know why it would, but there are only so many explanations for this. Also, where exactly are you measuring from?

Nice catch. I want to place my bet before this is resolved - If the upper isolator was removed, you will clearly lose a little height. Perhaps your shop owner friend had a set of BB's laying around and installed them as a little surprise for you (have you thought to ask him?). So lets say you started out with a 5.5" - 6" lift (6.5" minus the isolator, less if the bottom is missing as well). In 3 years, maybe that 4.5" coil has gotten tired and shrunk the whole shebang down to 4.5" total.

Also, what kind of weight do you have on your WJ. Steel bumpers? Winch? Full size spare? Roof Rack? Jet Ski hanging out the back hatch? Etc.

Just trying to spark up some ideas. I'm quite curious about the outcome!

This shows teh lower isolator clearly - no way the lack of an upper would account for the 2" spacer:


Measuring 22.5" from center of hub to fender lip:

Agreed. Compressed spring, no upper isolator, and smashed lower isolator could though...

I just noticed that you have an arb front bumper and warn m8000. That would account for some if not all of that 2".

No spacers in the rear:



Think I'll get some new isolators for the front and pull the spacers, see what I get.

I find it hard to believe that the front bumper and winch would cause a 2" sag - but who knows?

That bumper and winch combo weigh a lot more than factory bumper. Most people add 2" spacers when adding those bumpers. If u remove the spacers your gonna have a a lot of rake to the front. I would bet that this is the issue the whole time.

Maybe that is the mystery - I am checking with ARB to see if they supplied the spacers

ARB didn't - but my suspension guy did. Mystery solved. Maybe I'll see about getting longer springs after I put the long arms on.

I sent a note to info@rustysoffroad.com letting him know.

Thanks to all here for the help - especially for the info about the part number being stamped on the spring. If Rusty's had told me that in the beginning it would have helped.

I'm thinking new isolators would be a good thing to have from a comfort and noise level standpoint, what say you?

Glad to see the confusion and frustration resolved. I do love a good mystery!
