Well christmas is around the corner and I am thinking about asking for some FRPP 3.73's, eaton posi, FRPP 31 spline axles, TA rear cover.

I plan on adding a kenne bell 9spi kit to the car is why I am thinking 3.73 instead of 4.10 and why I want to beef up the rear so if I ever wanted to run a sticky tire at that power level I could.

I am trying to get a feel if I am chosing the right parts for this setup. is the eaton strong enough or is there a better option, 31 spline axles sufficent, etc.


I am asuming the 28 spline stuff is too weak for that power level but not quite sure when 33 spline is nessesary.
