    You should have a 4 digit gear code on the door sticker. It will be like this:

    B04A


    See what code you have, and use this:


    http://www.tacomaterritory.com/wiki/index.php/Gear_Codes

    First digit:
    • A = 7.5" ring gear
    • B = 8" ring gear
    Next two digits:
    • 01 = 3:42
    • 02 = 3:58
    • 03 = 4:10
    • 04 = 4:56
    • 05 = 3:15
    • 06 = 3:91
    • 07 = 4.30
    Last digit:
    • A = 2 Pinion, Open
    • B = 4 Pinion, Open
    • C = 2 Pinion OEM Limited Slip
    some '98-00 models have shown a BO code of "???" on the door plate; so far this turns out to be a 3.91 gear ratio, at least for the 5sp. RZN171L-CRPDKAB with factory 31s/265s should be 4.56 with the AT.
    Edit by Ed Quinones on 10-7-05: I used to own a 99 Prerunner ext cab 2.7L with auto tranny and gear code of B07A. It came from the factory with a 4.56 gear ratio.

    The 1st gen Tacomas with TRD electronic locker came with the older differential housing and the 7.5" ring gear and always with the 4.10 gear ratio.

    The 3.90 gear ratio equipped Tacomas came with the larger differential housing with the 8" ring gear. No factory lockers with these, only aftermarket.

    Respect your elder gen.
    Pink slider.
    All the ring gears in the rear are 8". Front are 7.5"

    If your R&P are factory, and you have an elocker, you have 4.10s.
