I am looking into a dana 60 arb locker for the front of my 2500. ive had a dana 70 locker in the rear before i broke the crown and pinion, sheared it right off. I went to a 2001 dana 80. I trust the arb name, and want the functionability. What i need to know is what am i lookng at for grenadability... is my 60 gonna bind and snap... is it gonna work great, what have your fella's broke, whats your experience with a 60 locker in the front? I do serious truck pulling im pushing 600 plus horsepower and over a 1000 ftlbs of torque, at last check. The truck is being further boosted in hp in march/april before the pulling season starts and im tired of only 3 wheels spinning, that is, the front right tends to stop. Please help i need to know my options and what could really and honestly happen. Thanks in advance
