    Just food for thought, with a 2-4” lift run as must caster as you can without vibration (5-6 degrees, there will be a sweet spot) with adjustable lower front control arms to get a better street manners. I recommend getting lower adjustable control arms with the mopar lift, it makes a big different getting another 1/2 to 1 degree. When I install these at the dealership I only do them with adjustable lower arms. Also if you don’t use 4hi on snowy street roads or for whatever reason vibration might not be an issue because unlike the JK the JL front driveshaft doesn’t spin in 2wd with the CAD.

    What adjustable lowers are you using with the Mopar lifts that you install?

    I normally use Rock Krawler front lowers. I like their arms and customer service for the price.

    I heard rough country makes adjustable camber bolts you can use on the mopar lower control arms as well

    So is the JL axle the same setup as a JK. 6 degrees at the ball joints with 90 degrees on the axle flat spots?

    From all the data that I've seen it appears the Caster for Rubicons seems to be in the 4.0 range (not much higher), and the Sport much closer to 6. So although the listed spec for Rubicon is 4.8 +/- 1 and the Sport is 5.35 +/- 1 the REAL difference in stock Caster is much more than 0.55, it's much closer to 1.5 to 2 degrees.

    For Rubicons running stock suspension (and plan to keep the suspension stock) the longer Mopar LCAs (from the 2" Mopar lift) will put your Caster up in the Sport range to provide much better on road tracking w/ much less chance of wander.
    Also if you lift your sport 1.5 to 2" the longer LCAs will restore your proper stock Caster set.

    Do the specs for the 2019 Moab follow the Rubicon?
