Billet machined Mazdaspeed 6 rear diff mount can survive all the abuse you can dish out
Add to wish list

The CorkSport Mazdaspeed 6 Rear Differential Mount provides a bulletproof design to withstand any abuse your Mazda can throw at it. Crafted from extremely lightweight billet aluminum, the CorkSport MS6 Rear Differential Mount uses only the highest grade hardware and hardened steel shear pins. Tested by some of the most powerful Mazdaspeed 6's around, you can be assured the CorkSport Rear Differential Mount can withstand whatever you can throw its way. Whether you want to upgrade your OEM mount to something more durable, or simply have a high horsepower mazdaspeed6 that has already destroyed your stock mount, this is the mount for you.

A very special thanks to Dennis Gardner (COspeed6 on MazdaSpeedForums) who tested this part on his MS6 equipped with a GT35 turbo. When asked about it he said "I threw everything I had at this mount and my engine blew up long before I could even make a dent in it"

2006 to 2007 how to installation instructions for a Mazdaspeed3 rear differential mount
I don’t know the other reviewer waa on but no rear diff mount comes with a front as well. If you buy a rearvdiff Mount that’s what you get. One of the first mods I did was to do. It’s rear diff mounts and I used this one for the rear mount. Very nicely made and works as you would expect. Been a couple of years now and still as good as new
It's a good part and it works however the problem with mazdaspeed 6 differential mounts is that both the front and rear mount on the rear diff brackets are trash and the corksport mount only comes with the rear mount not the rear front mount.
