My question is this..I have a 10bolt now w/ 4.56 gears and a detroit rear and auburn posi front. my question is this.. my freind has an 84 (dont shoot me just yet) jeep. the jeep has a 383 stroker pulling aroung 400 horses, he thinks his dana 35 and model 20 (w/ one piece axle) are weak. he mostly does sand dunes and mud. my question is which will break first on his truck (seeing as how he wants my axles) the 10 bolts, or the 35 and 20.
