So just to he clear, this WILL work with a 2012 JK rear dana 44 with 4.56 gears? Thanks
No, it will not. The application required for JK models Non-Rubicon would be the following model. Trutrac compatible with Jk rear Dana 44 Non Rubicon applications. Thanks for your inquiry.
Hi, would this work in a Dana 44 Rr axle 30 splines with a 3,54 -1 gear ratio. Thanks.
No, sorry it will not. Thanks for your inquiry.
Would this work with stock TJ Rubicon thick cut 4.10 gears or do I need a different ring and pinion?
For use with non-thick ring gears only. Thanks for your inquiry.
Is this compatible to Yukon 4.56 ring and pinion gear?
Yes - this is good for 3.92 and numerically higher so it will work great with 4.56.
