    Will 4.10 gears from non-elocker 05 Taco fit my 08 base 5lug Taco with 8" rear end? As far as I know only TRD off-road e-locker equipped Taco has 8.4" rear end....

    Any insight on this?

    Well I am going of this;

    All 2wd and 4wd T100's, '00-06 Tundra's, and ?? Sequoia's use a newer/stronger 8" 2-pinion diff. Tacoma 4x4's and Tacoma PreRunner's that don't come with the electric locker (aka "non-TRD), as well as V6 Tacoma 4x2's also came with this diff.
    This diff commonly and mistakenly called an 8.4" or 8.25" diff, possibly to imply its extra strength. The ring gear actually measures 8". The extra strength of this diff comes from the bearing cap/truss and large diameter pinion gear shaft.
    LSD's available is the TRD/Kazuma clutch-type 3-pinion LSD, the OEM 4-pinion Tundra TRD LSD, and the Detroit Trutrac.
    Lockers available are the Powertrax "Lock-right," "No-Slip," ARB Air Locker, Detroit Softlocker.This diff cannot be fitted to an older style 8" axle because it uses a larger diameter mounting bolt pattern and because more space inside the housing necessary to accommodate the large bearing cap. The different bolt pattern also makes it very impractical to swap in an electric locking Toyota diff (the whole mounting flange would have to be re-done using a special jig).
    - Carrier bearing truss and newer housing adds significant strength over V6 and 4cyl diffs
    - Uses V6 carrier bearings, larger pinion bearings
    - Uses shims for backlash adjustment instead of threaded adjusters
    - Twelve 12mm Ring gear bolts
    - 10mm axle housing studs with 14mm nuts
    - 30 splilne axles
    - 30 spline pinion
    * 4Runners do NOT use this diff at all. Late-model 4Runners still use the V6 8" diff above.
    ** This diff is NOT swappable with V6, 4cyl, high-pinion, or electric locking diffs. This diff cannot be fitted to an older style 8" axle because it uses a larger diameter mounting bolt pattern and because more space inside the housing necessary to accommodate the large bearing cap.

    You're right. I didn't see that he has a manual transmission. Automatics come with 4.10s.

    The non-TRD diff's in tacomas are commonly referred to as 8.4" even though the ring gear still measures 8".

    Does that mean the TRD Sport has the 8.4?

    You're wrong there. All 4x4 2.7s come with 4.10s. All 4x2 (PreRunners as well) come with 3.58s.
