I've been running Bilstein 5100s and Light Racing UCAs with no problem. I added a winch and Demello bumper which dropped the front about 3/4". To get back the 3/4" I picked up a 1/2" top plate spacers from Toytec. Keep in mind that the Bilsteins are the same length as stock.

With the 1/2" top plate spacers, the boot of the UCA ball joint rubs the spring at full extension. This is only a problem with both wheels off the ground as the sway bar will limit the travel.

Question is, has anyone else seen this rubbing problem when using a 1/2" top plate spacer?

I seem to remember that my replacement 5100's were noticably longer than the stock shocks I removed from mine. Maybe with the 1" top spacer you have too much shock extension?
Just a thought.
Might need to ditch the spacer and replace the spring with a stiffer one to get the nose back up.

So the Bilsteins are set at stock height, no lift?

Front Bilstein 5100's are the same length as stock. I am using a 1/2" top plate spacer NOT a 1".

They are at the top setting but where they are set doesn't matter. Full extension of the 5100 would be the same as full extension with an OME shock, or a stock shock, so others should see the same problem.

EDIT: Correction. In Bilstein's brochure, they claim the length to be 1/2" to 3/4" longer.

Bilstein's website shows the following for the 5100 that fits the front of the FJ:

Extended Length (IN): 22.56

I found one thread where they measured the stock shock length at 21.625"

Another shows 21.875"

..another they say is 21.5" but it looks longer.

..and aha! I found a thread about UCAs touching springs. Just depends on the search terms used.

My bad, I read 1/2" but my typing fingers left off the /2.
I have my original shocks in the shed and would be glad to measure them if you would like. I do remember laying them side by side and noticing the 5100's at least 1" longer but didnt measure the 5100.

No problem. Thanks for the offer VL. I believe I am all set from the post links I found above.

The OME shocks are also about 1" longer than stock and Toytec suggests the 1/2" spacers to get to a full 3" lift. I'm doing no different with the 5100s by adding the spacers. I'll jack up one side tonight to see if the swaybar limits the downward travel.
