This diff cover is everything that I hoped it would be. Customer service was amazing along with the quick shipping. It took 5 days to make the diff cover (as it says in the product description) and was at my front door the next day. After opening the package and seeing it in person I was blown away with how sexy it was. Definitely a chick magnet and will increase your man hood by at least 3 inches. Overall, nothing but great things from this product and would recommend it to anyone.

I finally got myself one of these beauties! Ordering and shipping was quick and painless, as always. Shipping was done via USPS, which I prefer. Since I'm in NC and Ruff Stuff is in CA, USPS is MUCH faster than UPS. Everything I order is here in 2 or 3 days max. The diff cover was everything I dreamed it would be. Pure beef! 16 lbs of amazingness! I like that they spot face the cover so a washer or bolt head can sit flat and tighten up properly. The only minor thing I see is the lead in/lead out nub from cutting the flange ring wasn't ground off. Also, note that these axles are METRIC. I called to see about how long of a bolt I would need to use and was informed they come with 5/16-18 bolts that are 3/4 long. They are, in fact, M8-1.25 bolts. At least the GM axles are. I can't attest to that on the Dodge axles, but since they're made by the same manufacturer, I would safely assume that they're threaded alike. If I spent the 7.50 on hardware, I'd want the correct stuff.

Questions and Answers

Ask a Question


Tim W. on -- Asked: what bolt size/rating do I need with the AAM 115 diff cover for my 2006 Dodge Cummins? Can I order new bolts with the diff? Thanks.

Answered: There is an option to include our provided 12 point head bolts. They are grade 8 and easier to get a socket and wrench on than the 6 point bolts.
