gears question? need help

[shootemupy2k]

first, to answer your gear questions.

upgrading to 3.73s would give you a nice boost in bottom end performance without sacraficing much in the way of fuel economy.

next, differential.

this depends entirely on the type of performance driving your most interested in doing. If you would like to do alot of autocrossing, your best bet would be with a good posi-traction differentail from EATON, AUBURN, or ZEXEL.
if dragracing is more your thing I would recommend richmond gears powertrax system. I just installed this sytem in mine and I coulden't be happier.

deff drag racing bu still wat is posi traction? and what is the thing u have? does it make both tires spin

[shootemupy2k]

a powertrax locker locks the two axles together, making them essentially a solid axle. But the system still allows for full wheel differentiation while turning, so no excessive tire wear. There typically cheaper and easier to install than your average positraction unit. On the down side though they make a little more noise for the first 1000 miles or so after its installed.
