I emailed Nitro about 4.56 gears for the front and here is there response:
There’s hardly enough demand to justify the 4.10, the only way we could make it happen is with the overseas crowd (mostly diesel) and 4.56 is way too low for them. We have no plans to offer 4.56 any time soon, and I’m certain nobody else will ever do them. What I’m getting at is don’t hold out for 4.56.

There advise was if you want taller gears go with the 4.10 because there may never be anything else.

4.10's won't be that noticeable of a difference over stock 3.73's. I bet they would have sold more had they made 4.56's

Seems like their target market is CRD vehicles running 35s (that's the equivalent tire size the necessitates 4.10s for the CRD gearing). And in doing so they're hoping to expand sales to anyone with 3.07 or 3.55s in the gas vehicles.
Basically just bones us guys with 3.73s since the jump to 4.10s, IMO, isn't even worth my time.... especially with the 5.7L.
Welp... time for the Dana 60's swap!
