This is our 3rd generation billet aluminum with solid rubber bushing mount. However, this one is taller than stock at 3/8". It is intended for lowered cars and it will reduce axle angle, which will reduce or eliminate axle wobble. It uses a solid rubber bushing to keep 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. They are used in the hardest launching Cobalt, HHR, and 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. This will work completely fine with our front trans mount and billet engine mount, but you will need to tighten all mounts in a sequence because this mount will rotate the engine so much.

Article on proper mount tightening sequence can be found here. 

Will not fit 2.2L cars. Also fits 5 speed HHR SS! Will not fit on automatic cars.

Confirmed fitment on 2.4L manual F23 cars.
