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.

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

Rotated Rear Trans Mount Gen3 install

ZZP was quick to deliver and provided prompt support before I started. I also ordered the zzp billet engine mount. I already had the zzp front trans mount installed from years earlier. It took all day to install the rear rotated trans mount. I was curious how this taller mount would align - and sure enough, it was a battle. I did all the work under the car while on jacks. Initially, I installed the mount and the trans bracket separately (per the GM manual). The problem was then aligning everything up to get the thru bolt in with the spacers. I couldn't tilt the engine enough with a crowbar to get the thru bolt all the way thru and engaged. So - I removed the mount and the trans bracket, and installed the assembly with the thru bolt and spacers outside the car. Then, I installed the full assembly back under the car - carefully making sure all the bolts (the 3 mount frame bolts and the 3 trans bracket bolts) would thread up, snug up and torq down. Somehow it bolted up without tilting the engine. Was there a benefit to installing the product? Not really sure. I subsequently installed the zzp billet engine mount - so I'm not sure the effect of either product in isolation. I purposely try to not smoke the tires - so I can't comment on wheel hop one way or the other. I did notice that the stock rear trans mount was worn/torn/damaged and needed to be replaced by something. Test driving the car did provide a much tighter drive experience (when accelerating and when changing gears/letting out the clutch from a stop etc). There is certainly more vibration/buzzing harmonics. For a reference - I have the 2006 Cobalt SS with the zzp stage 3 kit.

HUGE PROBLEM SOLVER

My cobalt sat over 6 months because of my axle issues due to the fact that my vehicle was lowered on coil-overs. This part was recommended by a friend of mine who also shops here... long story short my vehicle is now on the road rather than collecting dust and i’ve never been happier.
