I finally read this thread tonight. I have no idea if the birf eliminator is stronger than those birfs
I have not broken anything yet...but I do not hardcore rockcrawl either. I do run trails that have rock sections in them & am not always real nice to those axels if the section of trail requires it. I am running 529's & a Detroit so they do see some stress. They are basically Dana 44 axles & u-joint. I seem to remember they are necked down at the splines. The price is almost a wash with the new Longs, but those look plenty beefy.
