After waiting over six weeks, my aluminum differential case upgrade from Rlaarlo for my DSK arrived. The internals from my DSK's diff don't fit in it; it has a strange internal design. I've assembled diffs for kit builds and have rebuilt/serviced/tuned diffs in several of my cars and trucks.
I've been back and forth with Rlaarlo customer service three times, explaining the problem and sending photos. They claim it's the correct part and can't see any internal difference between the part in their DSK differential assembly video and the part I received.
I'm frustrated with the run-around I'm getting from them and I'm getting angry. I was a big fan of Rlaarlo and have five of their vehicles. That relationship may have ended.
Following is a photo of the DSK standard diff housing, taken directly from their DSK differential assembly video, and photos of the aluminum diff housing I received (similar area on each circled for clarity)... I think the difference is pretty darn obvious. And they claim they can't see any difference? Regardless of visible differences, the internals don't fit in it!
