Anybody running 4.56 gears on their 100 with 33s?

I’m curious to hear how many are running 4.56 gearing in their diffs on a 285/75/R16 tire?

I’m about to order some new third members with e-lockers for my 07 LX and I’m debating whether I should stick to stock gearing or do 4.56?

I have ZERO intention of going to 35s or anything above 33” tire on the 100 as I already have that setup on my 80-series with 4.88 gears.

When I’m fully loaded I do notice the tranny hunts for gears at elevation on the highway quite a bit, I have full armor etc so it’s much heavier than stock.

Curious to hear some feedback.

I’ve heard 4.56’s are a pain to do on a 100, something about needing some 80 series input shafts or something to make them fit. That being said I plan to figure that out after my next tire size upgrade.

Mathematically you’ll be over geared on 33’s but with all your weight that might not be a bad thing.

Way back when, I changed my '03 out to the stock 4.30s. Closer mathematically to the 4.56, but without any install headaches.

I appreciate the feedback guys. To be honest I am happy with the stock gearing as-is. Just figured if a 4.56 regear was simple I might go that route since this is the best time to do it, but it sounds like it's not a common thing to do.
