I just wanted to put this out there that i had some problems with my moser 12 bolt, and the bolts backing out of the ring gear a couple of weeks ago. I bought the rear 6 months ago from them directly, well i called them and told them what happened and they told me to bring it up to them and they would look at it. well they realized that it was not my fault and they fixed it for free. they replaced everything that was broke or contaminated with metal shavings, with out any hassle or bitching on my part. i just wanted to put it out there that they are a top notch company that stands behind their work. And Mike was a breeze to work with.
