4.56 Gears On Mostly Stock Build

Humm, 3.91 may fill the bill with a URD SC. What is the vendor? Yukon?

Toyota is the vendor.

3.91 is an OEM ratio in the GX460. The front carrier is not the same, so you need to swap the complete diff assembly or re-gear with a 3.91 and up carrier. But you should probably just buy a GX front diff if you're going that way. Front diffs are about $300 complete. Way cheaper than labor to setup and you get an OEM factory build. Rear would require a re-gear setup if you have an e-locker. As far as I know there isn't a 3.91 rear e-locker unless maybe it exists in other markets for the Prado 150. If not an e-locker it should be a bolt in swap in rear also. Rear diffs go for around $650 for a non-elocker gx rear diff. Just ballpark prices I've seen in the past few years.

3.91 is pretty close to 3.73, so I'm not sure it's worth the $. YMMV - literally and figuratively.

Well that one probably won't happen then :rain: I've got an e-locker that I am not willing to give up.

Thank you very much for the insight.

I believe you could re-gear your e-locker with the 3.91 rear ring and pinion set. You'd have to double check on that. I don't think there's a carrier break in the rear gear range, but I don't know off the top of my head. I think there is an OEM 3.91 elocker from a Prado 150 GXL or something like that you could order from a JDM supplier, but I'd guess it'll be $$.

Looks like Marlin Crawler has a special on 4.11 gears.... Specials | Marlin Crawler, Inc.

Now if I could magically change everything into a Toyota 8" High Pinion third member found in the 80-series Landcruiser. I would be good to go! :deadhorse:
