I got the Diff installed along with my Velox Driveshaft. Love it so far, not too bad but I can slightly tell its a bit slower and I can't start in 2nd gear from a stop as well as I use to anymore since I went to a 3.73 FD. They had to modify the Harrop Diff cover slightly, had to grind one of the fins a bit to fit my exhaust since I have a 3". Pretty happy with it aside from that. Here is a pic of the DSS driveshaft compared to the Velox driveshaft knuckles. As you can see from the pictures, the Velox knuckles are much smaller and the body seems to be slightly larger in diameter. But the Velox is rated over 3 times higher than the DSS, Velox is rated at 3600+ft.lbs and the DSS is rated at 900+ ft.lbs. Also, I have confirmed that I no longer feel the driveshaft hitting my short shifter the way I used to feel on my DSS driveshaft.
