Thread: 4wd OEM 3.73 gears

  1. #1

    4wd OEM 3.73 gears

    These are the gears off of my 07 Sierra. GM 8.25 front / GM 8.5 rear
    Truck has about 60k and they work flawlessly.
    I'm switching to 4.56 gears.

    This is would be great for a 6 speed with 3.08s or 3.23s.

    I'm asking 260 shipped OBO to the lower 48. Shipping isn't cheap for these so take that into consideration.
