I've got Core 4x4 Level 3 front lowers.Allens Offroad has some Core 44 arms I have been eyeing. Pretty reasonably priced too. That is probably the route I would go.
As stated before on here. Longer/adjustable arms do nothing towards correcting the angle. Like those brackets do.
Seriously. Your not hard core rock crawling with a 2" mopar lift either.
That's the only way I'd see those brackets touching anything
