Front 4.56 gears for 2012+

[greychevy]

Just curious if anyone has contacted or heard any chatter from gear companies about a front gear change solution other then doing a front diff swap? Before I did my swap I was emailing all the gear companies every week.

Also, anybody know if the 2012, 2013, & 2014 1500 front diffs, and rear axles are the same for all 3 years? Just wondering as a guy finally bought my 2012 front diff and his 2013 front diff had a different part number.
