Gear Ratio

[Aronda1125]

gonna be getting some custom tunes from DJ's for an Xcal3 and need to supply them my gear ratio. I can't find that spec anywhere. Do the 350's come stock w/ the 4:10 or does it vary?

Look at the axle code on the sticker in your door. Then google it.

I know D1 = 3.73 with limited slip. It's what my 350 has.

I should have mentioned that before, it says 3L. Didn't know if that meant anything, but i'll Google it now.

[R.Taylor]

Are you sure you are looking at the right code? Are you looking in the door or on the axle itself? Door codes start with a letter or are two numbers.

Gonna go check again, but i'm pretty sure it said 3L. I googled it and it is a valid code. Same as urs, 3.73 Lim. slip. But like i said, gonna double check the sticker. Thanks.

[R.Taylor]

I'm sorry, You are right. I googled it and found that the newer truck door codes are different than the older ones.

[Aronda1125]

It's cool. I went out and double checked just to make sure i wasn't an idiot.

Im pretty sure all srw's are 3.73 and the drw's are 4.10.
