This is our 2nd generation billet aluminum with solid rubber bushing mounts. Using a solid rubber bushing keeps them from creating vibration like the poly mounts have from being too stiff however they still drastically reduce wheel hop. These mounts are lighter than stock and are a great upgrade. These mounts are used in the hardest launching Cobalt, HHR, & Ion Redlines in our market including Ryan's 06 which has achieved 1.5 60' times and Matt's LNF, which has done 1.6 60 foots.

Will not work on 2004 Ion Redline, Ion 2.4L, or 2.2L cars.

Torque Specs: Mount to cradle 66 ft lbs, mount to bellhousing 74 ft lbs each

Weight difference: Stock 2.2#, ZZP 1.65#
