MMR Engine Block / Bellhousing Braces for Shelby GT350/R 5.2

MMR's Block / Bellhousing Braces help prevent common cracking of the engine block and or bellhousing on GT350 and GT350R Applications due to vibration and harmonics. 

If you are reading this, the chance of your block already being cracked is possible! Not to worry, the MMR Block braces will help prevent further damage to the block and transmission. If your block has not started to crack this will help prevent it!

The MMR Braces are an easy bolt on and connect the unsupported lower section of the left and right side of the bellhousing directly to the block, just like the 2020+ GT500. 

This product does not bolt to any plastic parts of the pan, it bolts to the steel inserts that go through the pan and contact the block, so this part does not place ANY stress on the pan whatsoever.

Because the block brace bolts to one of the original holes in the bellhousing that the transmission oil cooler lines connects to on some GT350 applications, it may be necessary to add a cable tie on applications equipped with the transmission cooler (2017+) to secure the oil lines after installation of the block brace on the passenger side.


Dont let this failure ruin your vehicles value due to non matching transmission and engine block #'s - this is cheap and easy insurance!!

Highly recommended for all Street, Drag and Road Race Applications - even if 100% stock!!
