Default Bolt-in diff arm reinforcement plates

We have a neat new product that I wanted to share. If you want to reinforce your differential housing arm in your own garage without a tig welder, this is for you:








$59 for a set, in stock and ready to ship here. We designed these to pair with our PPF delete kit and a BMW trans upgrade, but of course anyone can use them to eliminate the failure point that Mazda engineered into our diff housings.

Special thanks to Greg Peters from the CarPassionChannel for the pre-photoshoot photos. You can watch him perform the simple install in a upcoming video too.

Awesome!!! Was just thinking about how I should do this when I inevitably go to 3.63 gears.

Correct, they are aluminum. Also, I realized I uploaded the same picture twice. It will be fixed in 30 seconds so you can see the back side.

David,
As for installation, is it required to have the differential housing off the car to install these reinforcement plates, or can they be installed with the differential still attached to the car? I imagine it would be much easier with the differential removed, but can it be done with the differential housing still on?
Thanks!

You probably could make the holes with a right angle drill but I don't think you'd be able to get the upper bolts in with the diff in place. So even though you need to remove the diff, you don't have to split it open to weld it. So it's still a lot less work.
