To a mixing bowl add apple juice, apple cider vinegar, honey, dijon and kosher salt, whisk well.
Place pork chops in a gallon size resealable bag, pour apple juice mixture over pork chops. Seal bag while pressing out excess air, rub marinade over pork. Transfer to refrigerator and let marinate 2 - 4 hours (if possible turn bag halfway through marinating to move marinade around).
Preheat a grill over medium heat (about 375 degrees). Clean grill grates and brush with vegetable or olive oil (using tongs and an oiled paper towel).
In a mixing bowl whisk together cumin, paprika, garlic powder, black pepper, onion powder, cinnamon and cayenne pepper.
Remove pork chops from marinade and dab both sides dry with paper towels. Sprinkle spice mixture evenly over both sides of pork chops.
Cook on grill until center registers 145 degrees on an instant read thermometer, about 3 minutes per side. Let rest off heat 3 - 5 minutes before serving for juices to redistribute before slicing.
