MMR Engine Block / Bellhousing Braces for 2018-23 Mustang GT

MMR's Block / Bellhousing Braces help prevent common cracking of the engine block and or bellhousing on 2018-2022 Ford 5.0 Coyote 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.

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!!
