That's true, but that doesn't apply to the diffs we're talking about here. <img src="/forums/images/graemlins/wink.gif" alt="" /> (kinda irks me that Toyota decided to start doing that!) No problem Harry. Its a confusing area and the people that know haven't really organized all the info on this and put it in one spot.

Ok, so just to make sure I'm understanding right (b/c I seem to be pretty dense about this)...
If you want to go up to 4.88, then ideal is to start w/ a V6 3rd that came w/ something else (say 4.10) and upgrade the R&P. By going V6 rather than 4 cyl you get the better housing/gears/ more spiders, but lockers would be the same either way.
Best in long run to avoid the V6 3rd that came w/ 4.88 stock b/c yer stuck/limited in it's upgradability.
Correct?

I still say the 4cyl diffs are strong enough.......
I have never seen or heard of a 4cyl carrier breaking where a 6cyl wouldn't have......
Any thoughts???

This may be more about bearing life than strength. Bigger bearings will last longer. Although I would be interested in hearing about experiences with 4 cyl diffs and V6(or more) power.
Anyone?

I think the consensus has been that the V6 diffs aren't a huge upgrade from the 4cyl version. The 4cyl version is plenty strong. If you have the option to go V6, then do it. But don't go out of your way or spend a lot of extra money just to run the V6 3rd. It has some improvements, but they aren't major.
Also, lockers are not necessarily the same between the 4cyl and V6 diffs (I think someone was implying that). A V6 locker (carrier) will fit a V6 or 4cyl diff provided you use the correct bearings, but a 4cyl carrier will not fit the V6 diff without modification (a machined spacer to fit the correct bearings- contact Jim at Inchwormgear.com for info on that).
Because of this, ARB quit producing the 4cyl version of their locker (RD-01) and now only carries the V6 version (RD-23) since it will fit either diff using the correct bearings.
