The SPC a-arms don't come with the metal conical lower ball joint seat bushing that most other aftermarket a-arms have, which requires you to remove the OEM bushing from your stock a-arms. At least the first few batches of kits didn't have them. Maybe the current kits do.

Anyway, if you need these bushings you can order them from your favorite dealer. Ask for part number 40173-AL500. They are almost $10 each.

Here are the pics as I was installing my SPC a-arms on my other car.






BTW, for those of you with compression rod noises, if you need the similar bushing for that part, the PN is 40173-AC500. They look similar, but I don't know if they are the same. I thought to look for the 40173-AL500 bushing after reading about others getting the compression rod bushing.

 

same goes for the cusco a arms just did mine too

 

I thought about buying new ones. But I do have all the parts to pull this bushing. Still undecided. I've had my SPC arms for months and haven't installed yet. Probably do just before I get my new front tires.

By the way, nice write-up you did Gilley (on the a-arms installation). It's the one I've been studying.
