I have 3:55 now and I want to get a performance diff like an eaton. What do you suggest for a diff and gears. I have an aode with a shift kit, soon a 3000 stall. In summer it my daily driver thats why I went with 3:55, but I read that a lot of people do 3:73 or 4:10 on their daily drivers with no probs. What do you think?

I'd at least go with 3.73's, maybe 4.10's depending on how much highway driving you do.

I have an auburn locker rear in my car, and also run 4.10 gears, i don't do that much highway driving around here so i can't really comment on that but i love the gears even when i do around 70 75 im only at say 2500(roughly)

all depends on what you want, if i had not gotten such a good deal on my 4.10's i would have bought 3.73's, all depends on what you want.


ON the locker rear you have to be careful driving in the rain or damp weather, or when going around turns etc. unless you want it to get a little loose, but in a straight line traction is greatly improved

go with the 3:73's. They are better for all around driving. They work well with highway driving. I use to drive about 300 miles every weekend and the gears did great. I would have hated the 4:10's.

I don't think there will be a huge difference between 3:55's and 3:73's. If you really want a big difference and don't do much highway driving then go with 4:10's. The 4:10 will get you off the line hard. Great for going to the track.

yeah the 4.10's will get you off the line hard only if you can drive really good, or you have some really sticky tires, even then it is either gonna hook hard or just blow the tires away

yeah if you get the 4:10's make sure you have some sticky rear tires. If you go to the track a lot get some DRs.

that's a good choice. Good alround street gear.

Mine's a daily driver and I do all kinds of highway driving with my 4.10 gears. To be honest, I noticed no change in mileage from when I drove the same route with the previous gears, 3.55. Considering that the speedo was uncorrected for the 3.55's, from 3.27, my mileage may have improved a little--but I doubt it.

There is very little difference between 3.73 and 4.10 rpm wise. About 230 rpm at most speeds.

There is less than 200 rpm between the 355's & 373's when on the freeway.

I would go for the extra punch of the 373's.

I like mine a lot!
