What is my Gear Ratio?

[Josh P]

The tag is erased on mine

Is there a tag on the axle?

the LSD is clutch based, so it will wear out with time. the trutracs dont, as they are gear based like a torsen. and it depends on your gearing now. going from 3.73 to 4.10 for example, is something you wont notice imo. but 3.55 to 410, maybe? its all subjective, you may put a slight bit more power to ground, but imo if you didnt upside tires, it wouldnt be largely worth it. imo, if youve got a limited slip, may just be best to freshen it up and call it a day, or leave it entirely. let me know what youve got now

Mine is 45 = 3.55 ratio open slip,
What do you recommend best for improving performance

i'd say 4.10. keep in mind it will decrease highway fuel mileage though! and while doing it add somrthing like a torsen or truetrac when youre in there!

Gonna stick this in here for future

Solved - Transmission and Axle codes.

Well, I searched but was not able to find it on this site. So in case someone else searches for them, I thought I'd post this info here: Axle Codes L - Limited Slip Differential C - Conventional Differential Code ... Ratio 41 ...... 3.27C 42 ...... 4.10C 43 ...

I'm sure that this is probably already on here somewhere, but I thought that I would post it anyway. I know a lot of us want to know what the gearing on our trucks are, so instead of climbing underneath and trying to make out what's marked on a rusty old tag attached to the diff cover, or...
