For the people that have broken an output shaft on their 6060..... what method did you use to fix it? I assume if you made the power or traction to break it you could use an upgrade to something stronger. My buddy told me to look into something cryo-treated from liberty transmissions. I didnt realize the 07-09 was the only year with the 10 pound harmonic weight on the outout flange..... im sure this was a major contributing factor for the breakage along with not enough clutch slip.
