GM no longer offers the ZL1 1LE aluminum bushings as a kit

gm has in fact discontinued there 84341929 rear zl1/1le bushings. the only way to purchase them is with a rear cradle.

Guess you could call around and see if anyone still has them sitting on the shelf?

I am not sure that is a bad thing actually (with the exception of initial cost).

Having gone thru the process, it's a pretty intensive process, which usually requires heating up the rear cradle (potentially weakening the metal chemistry)

My performance shop opted for the more labor intensive route of sawing the rubber bushings out, rather than heating up the cradle. I was totally ok with that.

As a secondary reason, GM probably also wanted to make the price of entry steeper to protect the handling benefits of the ZL1 1LE. While the DSSV's are more track focused, the biggest upgrade to the stability and handling between the ZL1 1LE and the ZL1/SS 1LE are those solid rear cradle bushings.
