I was just thinking I might want to invest into some spare parts. Right now I dont have enough power to break anything but one day I will and I'd like to have a spare around when/if that happens.

So I was wondering what type of spare parts do some of you keep on hand? What is most likely to give under all this HP? I'm sure I will need a spare U-joint and maybe a ring & pinion set!?!?

I have things on shelves for the "incase"
I'd say anything you can put your hands on, I am always gathering

I currently have a few things I know could fail at any point...

Lift pump
Injector pump
Wheel Bearing/Hub assy
Carrier Bearing

and some small misc. stuff. But I just have a small garage that my truck doesnt even fit in so I cant horde too much. :o I think I need to get some U-joints.
