My buggy gears were straight cut. Sounds like kruse has buggy diffs too, if he is trying to keep the ratio as close as possible to the stock emaxx ratio. If you are still having issues maybe I can meet up with you, I am only about 30mins north of you in Slidell. We can compare my diff case to yours, as I have to take mine apart again to put the modified output shafts in the diffs to run my ths cvd cups.
