Re: Gears

considering its a 99 its prolly like 3.23s or 3.42s with posi and rear disk...?

EDIT: there should be a rpo code for it on the door or in the glove box

Re: Gears

Say i want the best 1/4 mile what should i put in?

Re: Gears

4.56's. :D For a daily driver, 3.73's would be most popular but there are many people who have 4.10's and drive it everyday.

To answer your question though, go 4.10's to get the best 1/4 times.

Re: Gears

i was just asking what kind of tranny do you have?
If you have auto and drive highway get 3.73
if you have auto and dont drive highway get 4.10
if you have manual and drive highway 4.10s or 3.73s
if you have manual and dont drive highway 4.10s

Re: Gears

3.73 is a good all around gear with decent performance

Re: Gears

well since u have 3.42 and go to 3.73 u wont feel that much of a diffrence u feel some thing but not as much as u would on 4.10. i had 3.42 and went with 3.73 but i wish i went to 4.10s. i to have a auto and i do a lot of driving my 1/4 mile didnt change that much from 3.42 to 3.73 but it is up to u. u want good 1/4 mile go for the 4.10 u would wish u did
