5.125 ring & pinion
 

Anyone selling?

is that the stock differential ring n pinnion?

Lol, no that is the Motorsport r&p for racing, several places will sell you a new one, used is a bit tougher and rarely are they sold without the entire diff assembly

I got lucky recently and purchased one from a wrecked grand-am car. I would contact Tom at The Parts Group and ask them if they have one or can get one for you. Last I knew none existed new on the shelf anywhere but I am sure others have more contacts than I do. As the previous comments says I bet you have a hard time finding a used one!

It's in stock at Mazda Motorsports, just checked

Thanks guys for the info.

I know RacingBeat is selling at $1497. Mazda Motorsports would be out my reach. Still hope that I can find a used unit here :)

Nice, thanks for the info as well! I hope mine lasts for a while but its great to know that the "source" is still making them :)
