IMO the problem is that the LSR Axles can not handle the droop angle as well as some of the other axles out there. Your rear shocks may be just a little too long and allow too much droop. You can have a stop added to your shocks or upgrade the rear axles only.
I have the MTS Kit and I had the same issue. I broke quite a few rear axles. Then I upgrade to Gorillas on the rear only and havent had an issue since. I later found out that Billstein had a few batches of shocks that went out just slightly out of tolerance. It wasnt much but it was enough to make an issue. I am not sure if that was my issue or not..... but the Gorillas handle the angle better.
