I am considering swaping to a 9 inch because of my busted 44 pinion and I had some questions
Definetly going spool. I don't like the detriot that much and I use twin sticks to drag the rear around when needed.
4.56 gears. I like the crawl ratio that ive got with the dual cases
35 spline shafts
now for what brand of gears. I have always heard good things about richmond gears and I saw that mark williams sells them with a 35 spline pinion. That should be alot stronger than the stock 28 spline pinion.
not sure what to do about the center section. nodular iron is what I was thinking.
Oh and where to get good 35 spline shafts
