Price is very steep. Even at list price the stock sway bar is $180. PN 10284146
A heavy duty stock replacement sway bar from GM is only $80 list. PN 12498643 and should be able to be had for less.
The labor to put a sway bar in should be an hour or less. I can do one in 30 min and I am not a mechanic.
I would suggest buying the heavy duty sway bar and having them install it, or doing the work yourself.
And yes, sway bars are known for cracking all the time on our cars. The heavy duty ones do not seem to crack as much.
