    I'm still in denial !!!!

    I'll wait for 04chase to swap to 3.73 from 4.11

    He has some good times on 4.11 awd

    Let's see if the higher gears will make a positive difference !!!!

    Subscribed. I'm trying to figure out what gears to run in my turbo 5.3 w/80E. 4.10's combined with the 80E 's 2.48:1 first gear is equal to "3.32's" and the 60E's first gear. I just want to make sure the truck will pull a decent 60' time.

    with the 5.3 the 410s should work well
    2002 Lightning - GT headed 5.5Litre w/ Twin 7665s
    2002 Silverado - 427Lsx w/ Twin gt4202s
    2010 Silverado crewcab Z71 - 5.3litre w/ procharger
    2000 Wrangler - 5.3litre with some stance
    2014 Xsport- 3.5 Eco boost
    412 Motorsports

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    My truck went faster with 4.10s than 3.42. However for daily driving you can't beat the 3.42s. If it helps you any it mph 126 on 4.10 and 122 on 3.42.
