While Dynatrac supplies the ProRock 44 with bracketry in OE position, they can custom build a housing just for you, too. We had them rotate the pinion up 3 degrees and rotate the knuckles back for 7 degrees of caster. This was perfect for us. Trailrunner tracks as if it's on rails and there is no driveline vibration. Dynatrac now offers this configuration for those with lifted JKs.
