Does GM still sell the 1LE rear lower control arms? I believe the part number is 10164151. Also, are these the same lower control arms that were included on the Bilstein Ultra Suspension equipped SS Camaros?

 

To my knowledge the arms themselves are the
same stamping, only the bushing is changed
(solid rubber, not perforated). Of course it may
be easier to just get the arms rather than doing
the press work (but it makes a dandy excuse to
buy a cheap Harbor Freight shop press).

The bushings make it firmer but the arm is still
a not-so-great, unboxed stamping.

Scoggin-Dickey ---> shows it if you use their
parts search.

 

I know it may show up on a parts search, but do you actually get sent the 1LE arms or do you get sent the standard lower control arms? GM sometimes will stop making a particular part and send you something else that may work in it's place. I had this happen before on a set of "aluminum" brake drums that turned out to be iron.
