rear gear with tko600

[93mustang]

i installed a tko600 in my 93 lx. it currently has a 3.55, and it stinks. what is a gear you would recommend to run on the street, mainly around town?. also goin 31 spline, what diff. would you go with? thanks

Well you won't notice a big difference with a 373 I'm a fan of a 390

i have a 3.73 in my car and i love it, buy a 3.90 is a good gear to

[93mustang]

i am about 90% on the 3.90, but also considered a 4.10? any takes on a 4.10?

[Metcalf Racing]

I like them real good. You'll be happy with either one

[penceracing]

the 3.90 gear will work for ya for sure. is it your dd or your track car??

[cstreu1026]

with the tall first gear in the TKO600 I would say 4.10's unless the car makes tons of power.

[penceracing]

never mind i read your ad again. a 4.10 would work good to for around town. it would be a great gear for street light to street light lol...

I haven't been here for a very long time.........but I'll throw my 2 cents in.
If you are going to race the car, then you need to take your rear race tire
circumference convert it into rpm's hitting the traps at, let's say 6000 in 4th.
Then play with the different rears you need to get to that point. Really just simple math. It will change dramatically with tire size.
Anyway, that's the science. For street fun I would guess 3.73-4.10 would work. I have the same tranny.

i think im going 3.90 looking to drop in a different setup soon with tons of power, so i think the 3.90 with the tall 1st will be best. thanks again for the input

Sounds like a plan. I have a Richmond spool 3.73 and it does it for me based on my wheel/tire size. Good luck.
