ok so now i decided maybe to get 3.73 gears for my gt in stead of buying some bolt on parts like pulleys and ram air, my car only has 26 k miles on it so i was wondering if i could get away with only buying the gears without the bearing kit and do i really need the tuner? i know it will set my speedo right, but i have a 5 speed so im not worried bout settin shift points, what else will the tuner help with?

 

i would also like to know how difficult is it to install the gears? any thing special i need to do the job?

 

Don't install gears unless you have precision measuring tools (i.e. dial indicators). Also, you could get away w/ not getting a bearing kit since your car is relatively low miles. Also, you need the tuner otherwise your speedo and odometer will be off. But you can use a tuner to put tunes on the car or to adjust aspects of the tune like timing, injector pulses/timing, etc.
