Differential/ Rear end parts choice

Sactown said:

Why would you be looking for a 9" rear end, I make well over 1000hp to the rear tires, ran the 8.8 with a tru-trac and 31 spline axles until just recently, I only changed to a spool to save weight. The 8.8 is a very good rear end with the correct parts.

Lighter. Runs cooler with an aluminum center section. Can have multiple center sections setup for street, strip, and road course. Center sections can be swapped in 20 minutes. With 4.56:1 and lower gears, there is always 3 teeth engagement as well as longer tooth engagement. The third pinion bearing adds substantial support.

I agree with what you said, but honestly how many people are really going to do that? Not many would be my guess. I'm not knocking the 9" or anyone that has converted to a 9" setup, I just making the point that it is not necessary.

Never said it was necessary, just giving another option. It would be the route I would take if I was looking to run that much power, but I also tend to overbuild. I could have gone with a 12-bolt for my current build but opted for the 9" because I knew there was no way I could bust it with what I was throwing at it. There are many advantages to running a 9", whether those are worth it is relative.
