You can check out the following article we did on the LCA's ... gives some pretty good insight:

It all seems pretty simple to me. This is because we engineer all of our components individually, to work with OEM parts.

That said; the 2005-2010 Mustang uses a 14mm UCA to Mount bolt. The 2005-2010 UCA is also 1" shorter, than the 2011+ UCA. Due to this, the mounting position on the 2011+ UCA Mount is also 1" further forward.

Here are some pictures to show the difference. These are BMR Components, UCA/Mount specific to 2005-2010 and BMR UCA/Mount specific to 2011+:

(The 2011+ Pieces are the pieces that appear "beefier") and have larger hardware/holes.









That said, here is a shot showing the 05-10 and 11+ OEM Pieces:





Here is why most aftermarket UCA will clunk when installed in an OEM Mount:



Here is why it does not clunk with an aftermarket mount:



And here is why the clunking is not so prevalent/common with OEM pieces, even though the tolerance is sloppy - they are designed to not clunk via:



As you can tell, the OEM engineering did not work well for us. We started getting a clunk at 450 miles on our car, due to the OEM Sleeve design not quite "holding on" for us.

The simple part is, MOST companies simply retained features from the 2005-2010 Style UCA....while we were engineering our parts to be specific for the 2011+ UCA System Change.

The Steeda UCA MOUNT appears to still retain the 14mm through bolt, so, a 2011+ UCA will not work. A 2011+ UCA WILL work on our 2011+ Specific UCA Mount.

I also suspect this is why Mr. Fair had issues with his previous design UCA Systems. He claimed the factory '11 has a 14mm bolt, IIRC, in his blog....but that is simply not true. Somehow he ran into some incompatibility issues with the components he chose to run - and I feel his opinion of aftermarket pieces is slightly flawed due to this - as our parts fit like a glove.

Hope that helps!

The j&m lca looks nice, and they do have a lifetime warranty on the bushings, which is why I got them. But I couldn't wait around for another bushing because it was pretty dangerous driving my car like that.

I got ya. I'm wondering if during your original J&M installation the bearings and ends of the control arms did not have enough grease put on them which caused the bushings too fail. Just wondering if that's what caused them to fail after two weeks.

It could be. I used all of the supplied grease, but maybe it wasn't enough.
