Good evening all,

Guys,

I have some questions, please. I recently bought a 37 half ton, and to be honest, I am not real familiar with the banjo differential setup and the torque arms / suspension.

Top speed of this old truck is about 50, and I am not wanting a high speed vehicle but it would be nice to be able to run 55 or 60 with it.

I want to keep this truck stock, but wondering about changing the rear differential and what is entailed in doing something like that.

Can the banjo diff be re-geared, or can the complete rear housing be changed out and if so, what kind of challenges, and what all would need to be changed?

TIA - KT
