Has anyone ran the stainless 5blade 475/87/1? Are they worth the extra money? My truck will still be used as daily/weekend toy. Can’t find much about them on duramaxs. And how would it compare to a fmw475/.87/.9?

Has anyone purchased the short block from Dmax store that pre assembled? Looking at what route I want to go.

Last weekend I bent the factory receiver, so I upgraded to the xd curt. This weekend I started to bend the end of the my frame. What are you sled pullers doing to prevent this. Thanks

I just had my second converter (1055-2) go out in 18000 miles. They told me that the first one had a bearing go out in it. Not sure about the second one yet. This time they put a 1073 and it. The third converter is downshifting hard right before I come to a complete stop like the first one did...

I brought a lb7 were the reluctor wheel came loose. Been doing some research, but still have some questions. I fished out 2 out of 3 bolts. Do I need to find the last one, or will it be fine left in oil pan? What are the knock pins? And the reluctor wheel only goes on one way right...
