Gear lightening

[Jeff Lee]

I have a dana 60 with all the good parts from MW; MW disk brakes, 40 spline gun-drilled axles, back-cut ring gear, CM axle tubes. What I do not have is an aluminum spool. I have a MW lightened steel spool. So for all my light parts that was one area I did not want to push. The bonus is every time a change a R&P for ratio it always looks new.
I'm still of the opinion these light parts are worth it however I have no back-to-back data to prove it.
I am looking at going from a 168 tooth flywheel to a 142 tooth flywheel. I guess that falls into that "center of inertia" theory Bill was talking about. From what I have read and heard, it will be worth the effort.
I hope...
