If you keep the 3 speed trans you will need the mechical brake.
I just don't know how well the phoenix will do.
If it was my truck. I would buy the 9920 and a 8xl feigao.
Gearing would start at the 15 52 and see how it does on temps.
For batts the 8000 mah lipos are great. You would need a lvc for 9920.
