WEll high pinion reffers to the pinion being on top on the axle center line. So High pinion is nicer to have since your driveshaft starts out high on the axle, farther away from the rocks and also lesser angles on the drive shaft.
Also, I think yours should have a low pinion from the factory. So an upgrade would be the high pinion but they mount differently since a XJ has coils in the front and your YJ has leaves.
