The stock upper transmission mount for the Sonic/Cruze is meant for comfort, rather than performance. The stock mount is weak and mushy.

Our upper transmission mount is made from billet aluminum, and a 1/2 pound lighter than stock! At the same time, its poly center has eliminated engine/transmission movement for hard launches and full power to the ground. 

This product has only been test fitted on the manual transmission 6 speed sonic. Does not fit the automatic transmission. 

An increase in cabin vibration will be present depending on driving conditions.
