I have a 2021 Rubicon Diesel JT. The standard equipment says it has the 4:1 Rock–Trac® Part–Time 4WD System. In the options, it doesn’t say anywhere that it’s been replaced since it has the Diesel engine, like it comments on the 3.73 gears instead of 4.10’s. The t-case no longer has an identification plate on it like my TJ did years ago.
