hey guys i am new to the cummins world, just bought an 08 with 20k on the odometer. i put it on the dyno yesterday and im pushin 750hp and 1120 ftlbs of torque. i plan on gettin her to be around 850+ hp and 1200+ torque. Before i do all this i need to redue the front and rear ends to hold up to the power. im wondering what ya'll recommend?
any help would be great!

 

I'd start by changing my handle
