    Default Gearing my truck

    I just lifted my 05 silverado LS and put 35's on it.

    I have already noticed it does not have as much zip as it did before the lift and feel like I should be thinking about changing the gear ratio on it.

    What should I go with? I was thinking 4.10's but I didnt know if that would be a huge difference from 3.73's and I dont wanna make it undriveable on the expressway...

    any advice???

    I would go with a 4.56.. You have a deep enough OD where you wont have a problem..

    It's not worth the expense to only go up 10%. The 5.3s like to rev, anyway.

    I agree with the 4.56s, I went from 4.10's to 4.56's in my Suburban and couldn't be happier with the single exception of not being able to cruise at 80 on the freeway anymore....well I could but the mileage suffers pretty bad.

    Cool gearing my truck

    Go with the 4.56s. I put 4.10s in my 05 Z-71 with 6" lift and 35s but wish I had installed 4.56s.
