hey there,
im in the process of purchasing 3:73 gears and aluminum driveshaft... is there anything in addition to these 2 components that i will need? do these 2 mods affect warranty issues? thanx for all your info!

You'll need some way to re-adjust your speedometer for the new rear gears. I had a performance chip burned and speedo corrected through that chip at the same time (AutoLogic chip). The cheaper way to do it is with a speed-corrector unitfor around $90.
Warranty should be ok...I think the dealer has the right to question repairs under warranty only if the Mods you did were the cause of the failure.
My dealer saw some of my Mods when I had the car in to replace a defective driver side window motor. He didn't saw anything about the Mods other than to ask me about their performance qualities...but maybe my dealer is just cool.

You'll also need gear oil and friction modifier.
